PCA Skin Intensive Clarity Treatment alleviates inflammation due to acne breakouts and reduces the appearance of hyperpigmentation. Witch hazel acts as a natural astringent to control excess oil production, remove impurities from the skin and tighten pores. Retinol helps reduce discoloration and improves skin tone and color by exfoliating dead skin cells for younger-looking, even skin.
