Dermaplaner gently exfoliates facial skin by removing dead skin cells and unwanted hair that can trap dirt & oil. To use, hold the Dermaplaner at a 45 degree angle and gently brush down the skin in the same direction of hair growth. Do not use dermaplanner directly over acne or irritated skin. Repeat every 3-4 weeks or once skin rejuvenation has been completed. Dermaplaning helps prep the skin for smoother make-up application and stronger product absorption for a beautiful glow to last longer.
