Botox cosmetic, or onobotulinumtoxin A, is a neurotoxin that prevents muscle contraction by blocking nerve signals to the muscle. Botox has been used for decades for therapeutic use and was granted FDA approval for cosmetic use since 2002. Neurotoxin injections have become increasingly popular due to high patient satisfaction with the results, as well as ease of treatment, and are currently the number one cosmetic procedure performed in the United States. These injections are used to treat wrinkles, mainly in the upper face, caused by facial movement referred to as dynamic wrinkles by preventing targeted muscles from contracting. Botox treatments are a quick and easy way to diminish facial wrinkles or prevent them from forming or deepening and to give your face a smoother, younger appearance. In general, you should begin to see results between 24 and 72 hours, but some patients may not see full results for five days or more. It takes time for the effects of Botox to reach its full potential. Once the initial inflammation and redness dissipate, however, you’ll see results more quickly. The delay is due to your body reacting and adjusting to the neurotoxin used for injections, which is normally inactive and paradoxically, non-toxic.
