Retinol

Retinol (Vitamin A). A derivative of vitamin A, this ingredient is particularly effective due to its small molecular structure, giving it the ability to penetrate deep enough into the skin that it can effectively stimulate collagen production. Retinol treats acne, fights signs of aging like fine lines and wrinkles, unclogs pores, and evens out the skin. Retinol stimulates a quicker renewal of skin cells. Using retinol can make your skin more sun-sensitive, make it a daily habit to use a broad-spectrum sunscreen that’s SPF 30 or above.
