Alastin Renewal Retinol .5 ($64)

“I suggest Alastin’s 0.5-percent retinol that in efficacy is stronger than any prescription. It has hydrating coenzymeQ10 and a hyaluronic booster, which are good for mature skin. And it’s affordable. It is also paraben-free and gluten-free.”

—Delray Beach, FL dermatologist Dr. Janet Allenby

“Alastin Retinol Renewal combines the benefits of an encapsulated retinol with their proprietary peptide complex that supports collagen and elastin, oat extract to calm the skin, antioxidants to help stabilize the retinol, and moisturizers to improve tolerability.”

—Dr. Waldorf

“This serum is an encapsulated format of vitamin A (retinol) to improve stability and allow for longer, slower delivery into the skin. It also contains antioxidant hydroxy-methoxy-phenyl, which supports natural hyaluronic acid production. And, it comes in a 0.25 strength too if you need a lower concentration.” 

—Dr. Shamban
