Native Ceuticals Retinol Treatment Serum helps to tone the skin and remove fine lines around the eyes and face. Our retinol exfoliates the skin, increases skin cell turnover, and stimulates collagen synthesis to create the appearance of younger & healthier skin. Use dropper to apply to skin around eyes and face.  Rub serum in circular motions into the skin but keep out of the eyes.  Continue until fully absorbed. It is best to use this product at night after you finish cleansing your face and before using a night cream. We recommend using a night cream immediately after your skin absorbs the retinol.
