Botox Cosmetic has been used for many years to decrease the appearance of frown lines on the forehead, crows’ feet around the eyes, lines on the side of the nose and upper lip, as well as platysmal bands in the neck and excessive sweating. The procedure takes about 10 minutes and no anesthetic is needed. Botox is injected with an extremely small needle and most patients report that it feels like a mosquito bite. The results become visible in 1-2 weeks and last 3-6 months. After that the procedure can be repeated if desired.
