Botox – Injection treatments that temporarily improve the appearance of both moderate to severe frown lines between the brows and crow’s feet lines in adults. BOTOX® focuses on one of the underlying causes of frown lines and crow’s feet—the repeated muscle contractions from frowning and squinting over a generous period of time. Your specialist will inject these muscles with BOTOX® Cosmetic to temporarily reduce muscle activity. You will start to notice a visible smoothing of your crow’s feet lines and frown lines between your brows.
