Retinol is a powerful free-radical scavenger used in skincare as an anti-aging and healing ingredient. Topically applied retinol is one of only 3 vitamins able to be directly absorbed by the skin. The other two are vitamins D & E. The antioxidant benefits of retinol act as cell renewal ingredients that is primarily used to give a renewed, refreshed look to every skin type. An additional benefit of retinol is its repairative effects on acne blemishes. One line devoted exclusively to retinols is Retriderm Skincare.
