With two Vitamin A derivatives, this serum delivers more than double the strength of retinoids than most retail versions. This product contains Retinol, one of the clinically proven compounds that reduces the appearance of fine lines and wrinkles paired with Hydroxypinacolone Retinoate that works similar to its sister molecule tretinoin (aka Retin-A®) but with little to no irritation. This serum also helps to reduce oily shine and increase circulation while delivering a punch of powerful antioxidants. It effortlessly absorbs and can be an important part of an anti-blemish regimen.
