This document provides information about Botox and dermal fillers for cosmetic treatments. As we age, collagen and elastin in the skin decrease, causing fine lines and wrinkles to form as the skin loses volume and hyaluronic acid. Botox temporarily relaxes muscles to smooth wrinkles while dermal fillers containing hyaluronic acid or calcium lift and restore volume. Botox effects last 3-5 months while fillers last 6-18 months. The document also gives details on treatments available at a medical spa in Fairfax, Virginia using natural fillers and Botox injections to prevent expression lines.
