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