New York City-based board-certified dermatologist
Marina Peredo, M.D., tells us that the retinol in Alastin Skincare's Renewal Retinol .5 is encapsulated, which improves stability and allows for slower delivery over time. She adds that "the antioxidants, including hydroxymehtoxyphenyl decanone, supports [the production of] natural hyaluronic acid."
What else is there? Dr. Peredo says that moisturizing silver mushroom and calming oat extract are two other ingredients that greatly benefit skin and ease any irritation associated with the retinol itself.
