Vitamin A Serum helps keep pores clear and keep skin renewed without adding extra oil to the skin. This water-based serum is gentle on your skin and will not cause side effects like other stronger forms of retinols because we use a mild form of Vitamin A, retinyl acetate. Retinyl Acetate is known to promote and support the synthesis of collagen and reduce the appearance of fine lines and wrinkles. This active also helps keep pores clean and helps remove excess oil which contributes to blemishes.
