"Sometimes, my sensitive skin can't always tolerate my go-to retinol serums, and I've had to learn that the hard way. After a particularly bad allergic reaction, I was nervous to return to retinol, so I've been using this alternative for the last few weeks to keep my skin in shape. My skin has stayed smooth and clear and it's even helped to fade a pesky dark spot I've been struggling with. The amazing smell and hydrating feel are welcome bonuses, too." — Brooke Knappenberger, Associate Commerce Editor
