Having used retinol for over 10 years, I’ve tried just about everything, from medical-grade powerhouses like Obagi and SkinCeuticals to reliable staples like Paula’s Choice and The Inkey List. Hands down, this formula is one of the absolute best I’ve found. What sets Sunday Riley A+ apart is the texture. It is a lightweight fluid that glides on effortlessly and absorbs in seconds with zero tackine SparklingTail · sephora.com
