ABSTRACT
Soft tissue augmentation with
dermal fillers has become an
integral part of most aesthetic
practices. Fortunately, adverse
reactions are usually mild and
transient. However, significant
adverse events such as
vascular occlusion also occur.
Vascular compromise occurs
because of embolisation and/
or compression material into/
onto the vasculature. In this
article, the author theorises
that late onset vascular
occlusion may occur not
only due to embolisation but
because hyaluronic acid (HA)
expands due to its hydrophilic
action and compresses the
facial artery or its branches.
He proposes that intravenous
steroids should be added to the
accepted reversal protocol. His
goal is not to promote this as
a definitive measure but rather
to establish a discussion on
treatment protocols that may
be helpful to other physicians
in the future.
W
ITHIN THE PAST 15 YEARS,
facial soft-tissue augmentation
has become very popular in
aesthetic clinics around the
world. Although most
biodegradable-type products
are considered safe, adverse events do occur that are
time-limited. The products have been observed to
have severe, persistent, and recurrent complications.
Histological examinations in these cases, often show
the presence and persistence of the filler1
. Dermal filler
complications are divided into ‘early’ and ‘delayed’ in
terms of time of occurrence and ‘minor’ and ‘major’ in
terms of severity1, 2
. Minor complications occurring
immediately or hours to days after injection include
injection site reactions, such as bruising, erythema,
pain and tenderness, swelling, and itching. These
events usually resolve within a week without
sequelae3, 4
. Severe vascular adverse events have been
reported in the glabellar and nasolabial regions after
treatment with both biodegradable and non-
biodegradable injectable fillers5
.
Although rarely reported in the literature,
complications related to interrupted blood supply to
the nose can occur with nasolabial fold dermal
injection. The exact mechanism of this event is
unknown, however it is widely accepted that vascular
compromise is a function of compression and/or
embolisation of material into the vasculature. It has
PATRICK TREACY, Medical
Director, Ailesbury Clinics Ltd

been theorised that, as injected hyaluronic acid (HA)
expands because of its hydrophilic action, the facial
artery, angular artery, or its branches, become
compressed. the facial artery runs in an oblique
direction over the mandible toward the nasal sidewall.
It passes under the zygomaticus muscles, crossing the
nasolabial fold. It turns to run in the alar crease and
along the lateral nasal wall, where it terminates in the
angular artery, which continues toward the medial
orbital rim6
.
There are several important factors that may lessen
the occurrence of adverse events. Before injecting any
dermal filler, a thorough medical history including
medication (especially blood thinners), allergies, and
scarring history (e.g. tendency for keloids) should be
taken. The injector should be well trained in injection
technique and know which filler to implant at which
depth. Understanding the anatomy, limitations of the
filler and proper technique can reduce the risk of adverse
effects. When complications occur, the practitioner
should understand how to manage them from
observation to surgical intervention7
.
Preventing side-effects
The best way to handle side-effects is to prevent them8
.
For optimum outcomes, aesthetic physicians should
have: a detailed understanding of facial anatomy; the
individual characteristics of available fillers; their
indications, contraindications, benefits, and drawbacks;
and ways to prevent and avoid potential complications9
.
Hyaluronic acid dermal fillers are the most widely used
injectables to augment facial volume without surgery.
They are popular because of their ease of
administration, predictable effectiveness, good safety
profile, and quick patient recovery10
. Since its
reformulation in mid-1999, the biologically engineered
hyaluronic acid filler Restylane (Medicis
Pharmaceuticals, Scottsdale, AZ, USA) elicits less than
one allergic reaction in 1600 treatments. Skin

L-lactic acid (Sculptra/formerly New Fill, Dermik
Laboratories, Berwyn, PA, USA) is considerably less
likely if a greater dilution and deeper injection
technique are employed11
. Inflammatory nodules are
likely to be caused by a low-grade infection maintained
within a biofilm surrounding the hydrophobic silicone
gel and the combination gels. Aquamid gel may prevent
formation of a biofilm through its high water-binding
capacity, explaining why late inflammatory nodules
are not seen after injection of this polyacrylamide
hydrogel product11, 12
. All gels act as foreign bodies. Host
response ranges from a few macrophages to an intense
foreign-body reaction with fibrosis, depending on gel
type. For polymer gels the filling effect stems from their
volume. For combination gels it stems from the
intended host foreign-body reaction to the
microparticles. Infectious nodules must be treated with
antibiotics. Granulomas must be treated with a
combination of both steroids and antibiotics or
excision12
.
Case study
Patient was a 37-year-old woman who received HA
injection to the left nasolabial fold. She had an
uneventful procedure but reported back to the clinic
with an erythematous reaction and some pain in the
nasolabial and malar area the next day. In view of the
vascular compromise she was immediately treated
with 150 units of hyaluronidase and nitropaste to the
reticulated area. Because the patient presented 24
hours post-procedure she was given 100 mgs of
cortisone IV and commenced on 4 mgs of
Dexamethasone PO. It was also considered appropriate
to inject 0.2 mls of a dilute solution of 50%
dexamethasone 40 mgs/ml into the area where the
hyaluronic acid was initially injected.
The patient became hypotensive during treatment
and was temporarily referred to the emergency room
until stable. This was considered secondary to the
nitropaste gel. The hospital was willing to allow the
patient to come back to the clinic for further steroid

within a 5 day period and 2 weeks later there was no
evidence of any residual vascular deficit.
Discussion
For the moment, there is no ideal dermal filler as they
have widely varying properties, associated risks, and
injection requirements that contribute to adverse
events for the patient. The majority of adverse reactions
are mild and transient, such as bruising and oedema
secondary to trauma or the physical characteristics of
the material itself.
However, although serious adverse events are rare,
vascular complications either arterial or venous can
occur that are related to volume of filler used and the
technique of placement in the region of terminal
vessels. It is possible that injected HA expands because
of its hydrophilic action and the underlying facial artery,
angular artery, or its branches, become compressed.
This results in vascular compromise that can lead to
skin necrosis unless it is immediately treated. The
author proposes that intravenous steroids and anti-
histamines should be given to all these patients.
There are also issues related to the recent use of
adjunctive lidocaine in fillers that may make vessels
more exposed to accidental infiltration. Lidocaine
significantly decreases pain during injection and
post‑injection with corresponding increased patient
satisfaction13
. The efficacy and safety profile of the
original filler may be compromised.
Rare complications with HA fillers include vascular
compression during or after the event which results in
reticulation some hours later and the author postulates
the use of intravenous steroids in these patients. These
patients normally show no evidence of vascular
compromise during injection. The protocol outlined by
Glaich et al14
calls for a coherent, sequential treatment
for vascular compromise resulting from injections of
hyaluronic acids. This protocol elaborates a sequence
of events that use topical nitroglycerin, hyaluronidase,
and other modalities to minimise the damage from
impending necrosis. Other authors have also published
guidelines for the treatment of impending necrosis
following soft tissue augmentation following injections
of hyaluronic acid15,16
. Based upon the experience with
hyaluronic acid occlusion, treatment for particular
fillers that occlude vascular structures should seek to
increase blood flow to the affected areas. This may be
accomplished by decreasing pressure in the anatomic
compartment(usingcorticosteroidsandhyaluronidase),
increasing blood flow (with sildenafil or similar drugs,
aspirin, and nitroglycerin paste), and increasing the
oxygen content to the affected tissues (hyperbaric
oxygen)17
.
Regarding reversal of a hyaluronic acid induced
embolus, the author recommends starting at higher

Figure 3 Effects of a large filler bolus
Figure 4 Effects of a small filler bolus
When a large bolus of filler material enters a small- or
medium-sized vessel, the material may flow retrograde to the
blood flow’s normal direction after it has filled in the distal
segment, because there is nowhere else for the filler to go. If
the filler bypasses a tributary during its retrograde flow, it may
enter this particular pathway and be carried to distant areas.

A
RECENT ARTICLE
byClaireColeman1
,
published in the
UK’s Daily Mail
newspaper, has led
to much confusion
with regard to the role of BOTOX® in
treating or causing depression. The
article was based on a study led by
Dr Michael Lewis of the School of
Psychology, Cardiff, Wales, who
followed 25 people who had
received BOTOX treatment for facial
lines and examined the idea of facial
feedback — where the expressions
we make with our faces affect how
we feel — and found that many
women who have the treatment for
cosmetic purposes feel depressed
because they are no longer able to
smile properly.
Previous studies, however, have
found that the treatment of frown
lines left patients feeling less
depressed. In 2006, Dr Eric Finzi and
Dr Erika Wasserman reported in
Dermatologic Surgery that treating
clinically depressed patients with
BOTOX on their frown lines actually
reduced patients’ feelings of
depression2
. Depression affects over
120 million people globally, making it
oneoftheleadingcausesofdisability
in the world. Although there are a
number of effective treatments,
therapeutic response remains
unsatisfactory and depression can
develop into a chronic condition in a
considerable proportion of patients.
An economic treatment option that
could provide long intervals
between treatments, and that is safe,
would be very important to doctors.
So, what is the truth? Is there an
actual physiological reason to
explain the different results?
The ‘grief’ muscles
The story begins in 1872, when
Charles Darwin recognised that
negative emotions, such as anger,
fear, and sadness — all prevalent in
depression — are associated with
hyperactivity of the corrugator and
procerus muscles in the glabellar
region of the face. Darwin called
them the ‘grief muscles’ and
formulated a new theory, known as
the ‘facial feedback hypothesis’,
which implied a mutual interaction
between emotions and facial muscle
activity. He published his new theory
in The Expression of the Emotions in
Man and Animals, which concerns
the genetically determined aspects
of behaviour.
In this book, Darwin aimed to trace
the animal origins of human
characteristics, such as the
tightening of the muscles around the
eyes in anger and efforts of memory.
Darwinevensoughtouttheopinions
of eminent British psychiatrists in
preparation of the book, which forms
Darwin’s main contribution to
psychology. His theory implied a
mutual interaction between
emotions and facial muscle activity.
Research into this stayed there
during the great upheavals of both
World Wars, until the rising
popularityofBOTOXmadescientists
review his facial hypothesis.
In 2003, Heckmann et al3
published data suggesting that
treatment of the glabellar region
with botulinum toxin could produce
a change in facial expression from
angry, sad, and fearful to happy, and
that this could impact on emotional
experience. Many therapists argue
that patients who had been treated
in the glabellar area reported an
increase in emotional wellbeing and
reduced levels of fear and sadness
beyond what would be expected
from the cosmetic benefit alone.
In 1992, Larsen et al4
provided
evidence that voluntary contraction
of facial muscles could channel
emotions, which were conversely
expressed by activation of these
muscles. Hennenlotter et al5
went
one stage further and showed that
botulinum toxin treatment to the

glabellar area stopped the activation of
limbic brain regions normally seen during
voluntary contraction of the corrugator
and procerus muscles. This indicated that
feedback from the facial musculature in
this region in some way modulated the
processing of emotions. Many other
researchers continued on this track, with
Havas et al6
noting that the processing
time for sentences with negative affective
connotation was prolonged in women
after botulinum toxin treatment to the
glabellar, and Neal and Chartrand7
speculating that the treatment interfered
with the ability to decode the facial
expression of other people. This is where
things remained, until recently, when
some authors suggested that this capacity
to counteract negative emotions could be
put to some clinical use during the
treatment of depression.
Reducing symptoms
of depression
A seminal article by Finzi and
Wasserman2
postulated that botulinum
toxin injected into the glabellar reduced
the symptoms of depression. The authors
provided data from an open case series
of 10 female patients. The article
contained a footnote from editor Alastair
Carruthers, who stated that the report
must be considered anecdotal as there
were no appropriate methods of control
used. In addition, there were other
methodological weaknesses, including
limited follow-up, lack of randomisation,
the absence of blind evaluation, and in
particular, the small number of subjects
included. Many felt that the methodology
of evaluating depression should have
been more rigorous.
At the time, I noted by letter that
patients’ self-report of depressive
symptoms by administration of the BDI-II
(Beck Depression Inventory) introduced
a significant bias. This is of more concern
because of the potential for secondary
cosmetic gain. While the BDI-II is an
accepted method of evaluating an
individual’s level of symptoms over time,
self-report in isolation was not considered
an acceptable method of diagnosing
depression. It was concluded that in
order to ensure that patients’ psychiatric
symptoms are accurately classified, a
thorough psychiatric interview must
be conducted.
In 2012, the Psychiatric University
Hospital of the University of Basel,
Switzerland, and the Medical School
Hanover, Germany, conducted a
randomised, placebo-controlled,
double‑blind trial8
. The authors
hypothesised that facial psychomotor
features associated with depression are
not just epiphenomena, but integral
components of the disorder, and may be
targeted in its therapy. To explore whether
attenuation of these features produces
alleviation in the affective symptoms,
they conducted a randomised controlled
trial of botulinum toxin injection to the
glabellar region as an adjunctive
treatment of major depression. The study
was investigator-initiated and carried out
independently of any commercial entity.
Participants in the study were recruited
from local psychiatric outpatient units
and psychiatrists in private practice. In
order to avoid attracting candidates who
were primarily motivated by receiving
this treatment for cosmetic reasons,
botulinum toxin treatment was not
explicitly mentioned. Exclusion criteria
included psychotic symptoms, suicidal
tendency, and clinical severity requiring
immediate intervention. The same
injection scheme was applied as that of
the open case series2
. At each study visit,
participants were assessed using the
Hamilton Depression Rating Scale with
Atypical Depression Supplement
(SIGH‑ADS), the BDI self-rating
questionnaire, and the Clinical Global
Impressions (CGI) Scale. To conceal
Havas et al
noted that the
processing time for
sentences with
negative affective
connotation was
prolonged in
women after
botulinum toxin
treatment to the
glabellar.

cosmetic changes from psychometric
raters, participants wore an opaque
surgical cap, which covered the glabella
and forehead during examinations.
The study concluded — for the first
time — that a single botulinum treatment of
the glabellar region with BOTOX could
reducethesymptomsofmajordepression.
This effect developed within a few weeks
and persisted until the end of the 16-week
follow-up period. The effect sizes in the
study were large and the response and
remission rates high. It is still unknown
how botulinum toxin actually reduces
depression and it is postulated that a
number of mechanisms may be involved.
As a result of the clinical data relating to
botulinum toxin treatment on emotional
perception, it is assumed that reduced
proprioceptive feedback from the
paralysed facial muscles is a relevant
mechanism of mood improvement.
As the authors did not include patients
who were cosmetically concerned about
their frown lines, it is unreasonable to
assume that an aesthetic benefit was the
major cause of mood improvement.
There is a small possibility of either
placebo effect or central pharmacological
botulinum toxin effects, including
possible pharmacodynamics or
pharmacokinetic interactions with
concomitant antidepressant therapy.
The ‘Botox Paradox’
So, who is correct? Does Botox reduce or
augment depression? How can the
findings of Dr Lewis be in complete
contrast to those of other researchers? I
believe that both are correct, and that the
answer to tise apparent medical paradox
lies with the original theories of Darwin.
Dr Lewis and colleagues found that
people treated for another muscle
(around the crows’ feet) left patients
feeling more depressed. This does not
contravene Darwin’s original hypotheses;
in fact it supports it. The muscles around
the eye are related to happiness and
smiling, and to restrict their movement
must interfere with the facial feedback
hypotheses in a converse way to those in
the glabellar area. We can only assume
that reduced proprioceptive feedback
from these paralysed facial muscles is a
relevant mechanism of mood
deterioration, and this is why they may
increase depression. Accordingly,
happiness can make you smile and
smiling can make you happy. It is obvious
that the facial musculature not only
expresses, but also regulates, mood states.
Botulinum toxin injection interferes with
the ‘facial feedback hypothesis’ originally
postulated by Darwin. (Perhaps it was my
sixth sense, but I never felt right about
totally removing crow’s feet around a
patient’s eyes.)
Conclusions
Thereisgrowingevidencethatbotulinum
toxin injection to the glabellar region may
be an effective, safe, and sustainable
intervention in the treatment of
depression. The reason for this has not
yet been fully evaluated, but we must
consider the concept that the facial
musculature not only expresses, but also
regulates, mood states. Owing to the
longer intervals between treatments, it
may also be an economic option, and the
safety and tolerability record of
botulinum toxin injections to the
glabellar region is excellent.
However, further studies are required,
including focus on muscles in the lower
sections of the face. It is possible that
treatment of the depressor angularis oris
and the mentalis muscles, for example,
may also have mood-elevating effects,
and may enhance the clinical effect of the
glabellar injection of botulinum toxin.
Modulation of mood states with
botulinum toxin may also be effective in
the treatment of other clinical conditions
involving negative emotions, like anxiety
disorders. There have also been recent
studies investigating the possibility of
botulinum toxin for bipolar disorder and
post-traumatic stress disorder (PTSD).
It is paramount to remember that
botulinum toxin to the glabellar region
may be an effective, safe, and sustainable
intervention in the treatment of
depression. The reason for this has not yet
been fully evaluated, but we must
consider the concept as depression
affects a huge number of people, making
it one of the leading causes of disability
worldwide.

Objective
The DUBLiN Lift: To establish the
clinical effectiveness of combining
five treatments in the rejuvenation of
the ageing face in an effort to increase
aesthetic effect, patient safety, and
reduce laser downtime.
The face is the area for which the majority
of patients seek cosmetic rejuvenation as
the convex lines of a youthful appearance
tend to flatten and droop as one grows
older. The younger face is characterised by
a balance captured in the classic shape of
the inverted triangle. The reversal of this
‘triangle of beauty’ as ageing proceeds
is considered generally less aesthetically
appealing1
. At present, a variety of different
dermatologic and volumising treatments
are available for facial rejuvenation. These
include chemical peels, dermal fillers,
intense pulsed light and radiofrequency
lasers, platelet-rich plasmas (PRP)
microneedling, microdermabrasion,
botulinum toxin injections, and laser
resurfacing. Each treatment has its own
relative benefit, as well as risks2, 3
.
In recent years, facial rejuvenation
has been revolutionised with the
development of CO2
fractional laser skin
resurfacing. This procedure benefits
from faster recovery time, more precise
control of ablation depth, and reduced
risk of post-procedural problems.
However, there have been cases of
hypopigmentation, hypertrophic scars
and skin mottling, most often seen on
the face, neck and chest when the laser
parameters are used more aggressively4
.
Furthermore, the technique does not
attend to chronological ageing problems
such as volume deficits resulting from
the loss and repositioning of facial fat.
This article examines the possibility
of combining five established therapies
in an attempt to address these deficits.
The facial rejuvenating therapies include
microneedling, low-dose UltraPulse
laser, PRP growth factors, Omnilux
633 nm light, and neurotoxins. The
technique is called the DUBLiN facelift as
an acronym of the procedures involved:
Dermaroller, UltraPulse laser, Blood
growth factors, Light (near-red 633 nm),
and Neurotoxin.
The author compared this method
to fractional laser skin resurfacing with
regard to the reduction of photoageing
and overall aesthetic effect. Neurotoxin
was used in both arms of the study.

ABSTRACT
T
HE FACE, AND
particularly the eyes, is
very important for contact
between humans, as this
area provides a window to
the rest of society with
regard to a patient’s level of health,
tiredness and emotional status, as well as
interest in others4
. Many health
professionals consider the periorbital area
of the face as the most important area
of rejuvenation as eye‑to-eye
communication occurs in approximately
80% of all human interactions6
. Both areas
present a barometer of a patient’s
chronological and environmental age, and
mastering the proper evaluation and
execution of their aesthetic rejuvenation is
paramount for all cosmetic doctors.
More recently, patients are seeking
effective facial rejuvenation procedures
with less downtime and low risks7
. This
change in attitude has been prompted by
a realisation of both doctors and patients
that the much hyped non-ablative
methods were often subject to
extravagant claims in terms of efficacy2–4
.
For many years, CO2
laser resurfacing was
considered the ‘gold standard’ in treating
photodamaged facial skin6–11
. Cutaneous
laser resurfacing with a fractional (CO2
)
laser involves the vapourisation of the
entire epidermis, as well as a variable
thickness of the dermis. Many physicians
stated that the ultrapulsed CO2
laser was
the most effective method of laser
resurfacing12–13
. Photodamaged skin is the
result of years of exposure to harmful
ultraviolet light and is clinically
demonstrated as a gradual deterioration
of cutaneous structure and function. This
results in the epidermis and upper
papillary dermis having a roughened
surface texture, as well as laxity,
telangiectasias, wrinkles and variable
degrees of skin pigmentation14–15
.
Although ultrapulsed CO2
resurfacing
lasers were considered the best

. Scarring after fractional CO2
laser
therapy is considered mainly a result of overly-aggressive
treatments and a lack of technical finesse. Physicians
have also recorded post‑operative infections leading to
scarring, although it is generally felt that these may be
prevented by careful history-taking, vigilant
post‑operative monitoring, and/or the use of prophylactic
antibiotics26, 27
.
With regard to facial rejuvenation, CO2
laser light at a
10 600 nm wavelength results in vapourisation with
thermal denaturation of type I collagen, collagen
shrinkage and later, collagen deposition. However, in
very deep rhytides, acne scarring and severe elastotic
changes from sun damage, fractional CO2
therapy
requires multiple treatments to achieve the same results
as the older lasers28
. A number of studies have evaluated
using different laser combinations in the same session in
order to improve collagen deposition, with a wider zone
of fibroplasia6–9, 28
. Owing to the inherent risks of fractional
laser skin resurfacing and its inability to deal with some
evidence of chronological ageing, it was advocated to
here establish the clinical effectiveness of using a
multi‑procedural approach to volumisation and collagen
regeneration. The author used microneedling with low
energy laser, and platelet rich plasma (PRP) to address
these issues.
Collagen remodelling and fibroblast
stimulation
It is recognised that the most important rejuvenation
process for photoaged skin is the collagen remodelling
process, and dermal fibroblasts are known to have the
most important function29
. Rejuvenation of skin injury
caused by UV light is a complex process that organically
involves cytokines interacting with a number of growth
factors and control proteins28
. The procedures evaluated
included PRP, microneedling, and Omnilux 633 nm
near‑red light, with neurotoxins as an adjunct to low-level
fractional laser skin resurfacing. Cells in the epidermis
and dermis can be targeted by microneedling and
Care should
be taken when
treating sensitive
areas such as the
eyelids, upper
neck, and
especially the
lower neck and
chest, by using
lower energy and
density, as scarring
has been noted in
these areas.

treatment option, they had many post-procedural
problems16, 17
, including prolonged post‑operative
recovery, pigmentary changes, and a high incidence of
acne flares and herpes simplex virus (HSV) infection18, 19
.
Many patients complained of oedema, burning, and
erythema that sometimes lasted for many months20, 21
.
The implied risks and long downtime made many
patients reluctant to accept this method of treatment22, 23
.
More recently, fractional resurfacing lasers have
addressed many of these earlier problems with benefits
of faster recovery time, more precise control of ablation
depth, and reduced risk of post procedural problems8
.
These lasers are extremely versatile, in that they can be
used for the treatment of facial rhytides, acne scars,
surgical scars, melasma and photodamaged skin, and
many have entered the market at the same time24
.
With the advent of fractional laser skin resurfacing, the
number of completely ablative resurfacing cases has
declined for most practitioners. However, care should be
taken when treating sensitive areas such as the eyelids,
upper neck, and especially the lower neck and chest, by
using lower energy and density, as scarring has been

All skin biopsies show the effect of thermal treatment with thermal coagulation
of the epidermis and superficial dermis
puncturing the skin with tiny, sterile needles. Typically,
this is done with a specialised instrument called a
microneedling device.
Controlled studies have suggested that the application
of autogenous PRP can enhance wound healing in both
animals and humans29
. Five major growth factors such as
transforming growth factor (TGF), insulin-like growth factor
(IGF), platelet-derived growth factor (PDGF), epidermal
growth factor (EGF), and vascular endothelial growth
factor(VEGF)areknowntoberelatedtothewound-healing
processes28
. These growth factors are released from
platelets, and the production of collagen and fibroblasts is
stimulated by IGF, EGF, Interleukin-1 (IL‑1) and tumour
necrosis factor (TNF)-α34, 35
. In vivo studies report TGF-β to be
the most stimulative growth factor. PRP may be used for
dermal augmentation and Sclafani observed aesthetic
improvements of the nasolabial fold in less than 2 weeks,
and the results lasted for up to 3 months28, 29
.
Research design and methods
This multi-centre randomised study included 44 patients
of skin types 1 and 2 aged between 39 and 68 years,
presenting with photoageing of the skin, 37 of whom
were women and seven were men. The subjects
presented with the typical hallmarks of chronological
and photoageing, such as expression lines, rhytides,
wrinkles, eyelid skin laxity, dermatochalasis, lowered
brows, lateral hooding, and prominent fat pads. All
patients were subjected to a programme of skin
tightening and neocollagenesis by one of two methods:
conventional fractional laser skin resurfacing (Group 1) or
the DUBLiN Lift (Group 2). The mean patient age in Group
1 was 49 years (range 37–71 years) and in Group 2 was 55
years (range 41–76 years).
Fifteen patients underwent Lumenis ActiveFX™ with
settings as (energy) 125 mJ and (rate) 19 w CPG 3/5/4.
Twenty-nine patients received the DUBLiN Lift, a
three‑phase combination of established treatments with
microneedling, platelet growth hormones, near-red
633 nm light, and low-energy UltraPulse fractional CO2

three areas 1 week prior to the other treatments as an
adjunct to the laser resurfacing.
The DUBLiN Lift was introduced as three phases over a
period of 3 weeks. Phase 1 included Dysport® at dilution
3.5 : 1 to three areas — glabellar, frontalis and periorbital.
Phase 2 introduced intense fibroblast stimulation and
modification through microneedling, PRP growth factor
induction, and near-red phototherapy. Phase 3
administered the low–level (CO2
) UltraPulse laser at
100 mJ 14 w CPG 3/5/2, and adjunct near-red 633 nm
phototherapy. The study evaluated post-procedural
aesthetic results at 2 weeks, 4 weeks and 12 weeks. The
length of downtime, patient discomfort and adverse
side‑effects were noted for each phase.
Clinical assessment of patients in each group was
made at 2 weeks, 1 month and 3 months post‑operatively
in the presence of two aesthetic staff. The degree of
improvement in photoageing was based on the degree of
re-epithelialisation rate, reduction of rhytides, reduction
of tactile roughness, and loss of hyperpigmentation and
telangiectasias. The prolongation and severity of
erythema as well as the presence of negative side-effects
(e.g. herpes) were also recorded.
The efficacy of treatment was evaluated using a
variation of the five-point scale (Table 1) originally
suggested by Dover et al36
. Investigators and patients
evaluated efficacy using palpability assessments and
change from baseline score at 0, 6 and 12 weeks. A total

global score was recorded in each patient based on the
addition of points obtained from six photodamage
variables. The degree of perceived improvement in
overall aesthetic effect reflecting chronological age was
assessed separately by patients and physicians using the
Wrinkle Severity Rating Scale (WSRS) and the Global
Aesthetic Improvement Scale (GAIS). The WSRS is
recognised as a valid and reliable instrument for
quantitative assessment of facial skin folds, with good
inter- and intra-observer consistency5
. Wrinkle severity is
measured using a wrinkle severity rating scale with 1
being absent and 5 being extreme. By allowing objective
grading of data, these proved useful clinical tools for
assessing the effectiveness of facial volumisation with
PRP and microneedling–633.
Interventions
The following treatment protocols were used for this study:
Lumenis ActiveFX CO2
laser, Traylife PRP, Omnilux 633 nm
red light, Dermaroller®, and Dysport®. All participants
received selective regional anaesthesia blocks with 2%
lignocaine plus adrenaline, a topical combination
anaesthetic of 23% lignocaine, and prophylactic Valtrex
500 mg twice daily for 8 days. Valium 5–10 mg stat was
given as a pre-medication to some patients. A post-
procedural advice sheet and Nurofen or codeine with
paracetamol — as required — was also given to patients.
Clinical assessment of patients in
each group was made at 2 weeks, 1
month and 3 months post‑operatively in
the presence of two aesthetic staff.

The ActiveFX is a protocol of settings applied in
conjunction with an improved computer pattern
generator to the ultrapulsed CO2
laser (UltraPulse
ENCORE, Lumenis Ltd). Technical differences between
this non-sequential fractional device and the older
ultrapulsed CO2
include tissue bridges left between spots,
resulting in faster healing time, and less thermal damage
to the basal cell membrane. The device has a smaller
spot size (1300 mm rather than 2500 mm), resulting in
less post-procedure erythema.
The computer pattern generator lays down a random
series of spots rather than a sequential sequence
resulting in less overheating of the treated tissue. This
application is termed ‘Cool Scan’, and was used with
every patient in the study.
The Traylife Kit (PRP) (Promoitalia Wellness Research)
provides blood plasma enriched with a concentrated
source of autologous platelets that releases a number of
growth factors and other cytokines that stimulate the
healing of soft tissue.
Omnilux Revive™ (633 nm) (Photo Therapeutics, Inc.,
UK) stimulates fibroblast activity, leading to faster and

whose data was already on file. Patients in both groups
were administered Dysport® neurotoxin 1 week prior to
treatment to complement and preserve the overall
aesthetic effect. The study evaluated post-procedural
aesthetic results at baseline, 6 weeks and 12 weeks by
means of a scoring system based on Dover’s photoageing
scale, as well as using the WSRS and GAIS.
Histological results were obtained from both groups
showingthedepthoflaserpenetrationandconsequential
formation of new collagen. All skin biopsies showed
thermal coagulation of the epidermis and superficial
dermis in a depth ranging from 85 to 113 µ. The zone of
residual thermal (coagulative) damage was less in the
Group 2 patients, in whom less laser energy was used.
The best neocollagenesis results — at 3 months — were
evident in Group 1 where one patient had evidence of
effect at 700 µ. This was reflected in the patient’s skin,
which continued to improve over the period. Owing to
the variance in energy of the CO2
laser in Group 1 and
Group 2, it was expected that the documented depth of
histological ablation and thermal effects would vary
between them. Responses of aesthetic effect were
evaluated at 6 and 12 weeks after baseline.
The two methods appeared to produce different
clinical improvement of lesions and rhytides. The GAIS
for photoageing for the DUBLiN lift improved from 13.2 to
10.2 at day 30. This compared to 13.8 at baseline and 9.6 at
day 30 for conventional fractional laser skin resurfacing
alone. The score for fine lines was the most significant
reduction, dropping from 3.6 at baseline to 1.4 at day 30.
The score for reduction of coarse wrinkles (3.2 at baseline
to 2.2 at 6 weeks) was more difficult to interpret in this
heterogeneous age grouping, with older patients
requiring the conventional ActiveFX settings rather than
the ‘softer’ settings.
According to investigator-based WSRS and GAIS
assessments at 3 months after baseline, the DUBLiN lift
was superior in 62% and 55.2% of patients respectively,
while fractional laser skin resurfacing was superior in
33.3% and 34.4% of patients. (P < 0.0004). An ‘optimal’
cosmetic result was achieved in a higher percentage of
patients in Group 2 compared with Group 1.
Investigator-based and patient-based ratings using both
the WSRS and GAIS indicated that the DUBLiN lift was
moreeffectivethanconventionalablativelaserresurfacing
in creating cosmetic correction to the lower face. This
resulted from the volumising effect of adding
PRP to the larger folds in this area. At 3 months
post‑treatment, a higher proportion of patients
showed a greater than or equal to 1-grade
improvement in WSRS with the DUBLiN Lift
compared with fractional laser skin resurfacing.
The author suspects the PRP may have a longer
aesthetic effect when used in association with
microneedling and 633 nm light than previously
noted27, 29
. However, the results were almost
reversed whenever periorbital rejuvenation was
assessed alone, with almost every patient (93%)
favouring conventional fractional laser skin resurfacing.
Investigator-based GAIS assessment of this region at 3
months after baseline indicated that fractional resurfacing
was superior in 93% of patients, while the DUBLiN Lift was
superior in 6.8% of patients (P = 0.0025).
Objective results
Re-epithelialisation occurred in all
laser-treated areas of both groups by
day 7, and this appeared to be clinically
similar for both procedures. Mean
duration of erythema was 6.9 days
after resurfacing (range 4–10 days) in
Group 1 and 4.2 days in Group 2 (range
3–7 days). This appeared to be in
keeping with previous studies37

patients reported having no ‘crusting’
effect remaining on their face after 6 days. Residual
