How Does BOTOX Work?
Botox blocks signals from the nerves to the muscles. The injected muscle can't contract. That makes the wrinkles relax and soften. Botox is most often used on forehead lines, crow's feet (lines around the eye), and frown lines. Wrinkles caused by sun damage and gravity will not respond to Botox.
Injectable wrinkle fillers can give you a more youthful look for a fraction of what a traditional facelift costs. Most will fill lines and wrinkles in less than 30 minutes with results that can last from 4 months to more than a year. Injectable wrinkle fillers, unlike Botox injections that relax the muscle under a wrinkle, fill the line, crease, or area with one of several different substances. As a result, trouble spots disappear. Fillers can also be used as "volumizers," plumping and lifting cheeks, jawlines, and temples; filling out thin lips, and plumping sagging hands. The most popular category of wrinkle fillers is hyaluronic acid. Each type works in a slightly different way with varying results.
