It gently exfoliates facial skin by removing dead skin cells and unwanted hair that can trap dirt and oil. To use, hold the skin peeling blade at a 45 degree angle and gently rub the skin in the same direction as hair growth. Do not use the exfoliator directly on irritated or acne-prone skin. Repeat every 3-4 weeks. Please sterilize your skin peeling tool before and after each use.
