CNP Invisible Peeling Booster Essence: This peeling booster introduces a new concept to me—it does not require any wipe or rinse-off after applying. It is used in the first stage of skincare after cleansing to reinforce its effect of removing dead skin cells. It includes Polyhydroxy Acid (PHA), a low-stimulation exfoliating ingredient, and The Natural Moisturizing Factor (NMF) Complex to enhance the water-holding capabilities of the skin. With a watery texture and a strong chemical smell (contains fragrance), it absorbs into my skin, leaving it with a soft, pat-down finish. It helps with skin texture exfoliating, but very gently.
