Exfoliation Redefined. Dermathod's priming peel pads use a combination of PHA + LHA to gently exfoliate the skin, and promote collagen production. This is a slow releasing exfoliating treatment which should remain on the skin. Great for acne, fine lines, hyperpigmentation. They can also be used on the body for issues like Keratosis Pilaris. For at home use it’s recommended to be used 2-3 times a week
