Having Botox injections is a relatively simple and fast procedure. Either Dr. Chetty or our Cosmetic Nurse Specialist, Isabel Soriano, will first examine the treatment area to determine the most effective and appropriate injection site. The skin is then thoroughly cleansed and numbed using a topical cream. When numbing has taken effect, typically after about fifteen minutes, Botox can be injected.nnAfter receiving Botox injections, you may experience some redness, soreness, or bruising at the injection site, which should subside quickly. You can return to your normal routine immediately after receiving the injections if you choose, but avoid exercise or other strenuous activity for at least 24 hours. Botox results are typically visible about 3-4 days after receiving injections, and last 3-4 months on average.
