Botox is used for both esthetic and therapeutic reasons. The best part is you get to enjoy the esthetic and therapeutic benefits together regardless of your reasoning for getting it. The active molecule in Botox is a highly refined purified protein that helps relax muscle function. Esthetically the relaxation of targeted muscles helps to prevent wrinkles providing g a smoother younger appearance to your skin. Therapeutically the relaxation of the muscles helps to reduce headaches, migraines, clenching and grinding of teeth. Botox typically needs to be administered every 3 months to make it most effective and continue to keep the muscles in a relaxed state.
