Clinicians Complex Retinol-A Serum contains the highest clinical levels of (10%) pure retinol & retinyl palmitate (vitamin A) in a matrix of protectant silicones with vitamin E, lipids, squalane, and avocado oil. Retinol increases cell production in the top layer of the skin, resulting in a rejuvenated appearance and renewed healthy, youthful glow. Skin cells look smoother helping reduce fine lines, wrinkles, and improving photo damaged skin. Retinyl palmitate is converted to vitamin A dramatically improving skin tone while restoring elasticity and improving texture and vitality. Retinol-A Serum utilizes an advanced silicone matrix technology to ensure the optimum potency of retinol and retinyl palmitate by protecting all active ingredients from oxidation. The silicone matrix also works as an innovative delivery system allowing maximum penetration of these powerful ingredients deep into the skin. This all-natural, preservative free formula moisturizes as well as restores skin’s tissue to a healthy, more youthful appearance.
