Correcting retinol A prized ingredient in facial care products, retinol is highly recommended by cosmeticians… and with good reason! It’s now found in many of the best anti-wrinkle creams. Although most manufacturers don’t reveal the concentration of retinol in their products, it takes only a small amount to fill in wrinkles, promote the release of collagen, and actively assist with cellular regeneration. This gives skin a fuller, healthier appearance. Our suggestions: RoC, Retin-Ox Correxion 5-in-1 Skin Perfector SPF 25 and La Roche-Posay Redermic R. These products rely on retinol to diminish the appearance of wrinkles and fix uneven skin tone.
