Botox reduces mimic wrinkles on the face (frown lines, forehead lines or  "Crow's feet" in the eye area) through a weakening of the muscle contraction and the resulting relaxation of the overlying skin. The effect is temporary and is reduced depending on the metabolism and physical activity of the patient.  

Botox is a protein that relaxes the muscles for 3-6 months. It has been used in aesthetic medicine for decades to help smooth out wrinkles on the face. By injecting Botox into certain areas of the face, the muscles responsible for human facial expressions are so relaxed that the skin is significantly tightened. Thus we are able to permanently reduce wrinkles and prevent their formation.
