Botox is used to treat frown lines, forehead wrinkles or crow’s feet, but also lines on the nose (bunny lines), the chin and wrinkles around the corners of the mouth. The wrinkles in the skin appear in these areas due to the frequent contraction of the muscles, i.e. facial expressions. The treatment relaxes the muscles, the skin recovers and becomes smoother. As a result, the wrinkles that have formed in the epidermis also fade over time.
