12 in a pack, The 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 down the skin in the same direction of hair growth. Do not dermaplaner directly over acne or irritated skin. Repeat every 3/4 weeks or once skin cell rejuvenation has been completed. Dermaplaning helps prep the skin for smoother makeup application and stronger product absorption for a beautiful glow that lasts longer.
