Lines and wrinkles around the eyes and forehead are often referred to as dynamic lines of the face. They are caused by repeated muscle contraction, and increase in prominence from about 40years onwards. It is a simple and fast procedure to use some muscle relaxing injections to rejuvenate the skin and smooth out these lines. It is perfectly safe and a course of treatment lasts 3-4 months. After this time the skin will relax but it will never be worse than the condition at the beginning.
