Wrinkle relaxers such as Botox Cosmetic, Dysport and Xeomin are injectables that are used to temporarily improve the look of your moderate to severe wrinkles in between the brows (frown lines), eyes (crow’s feet), and lines around the mouth without changing the look of your whole face. The untreated facial muscles will still work normally, allowing you to freely show facial expressions, such as smiling, in untreated areas. Depending on the area treated, results may last up to 4 months.
