Botox Cosmetic is a neuromodulator that works by blocking the communication between nerve endings and the facial muscles that those nerves control. This neuromuscular junction blockage relaxes muscular contraction and, in so doing, significantly decreases facial fine lines and wrinkles. Botox Cosmetic received FDA approval in 2002, and since then, has been used to treat millions of patients.
The treatment is safe and effective. There is no down time.
The maximum facial muscle softening occurs 1 week to 1 month following injections. The treatment effects typically last between 4-6 months and should be repeated in order to maintain the desired effect.
