Racking up more than 1,000 reviews and nearly 50,000 loves from other Sephora shoppers, the Glow Recipe Pineapple-C Brightening Serum ($49) gets some of its vitamin C from brightness-boosting pineapple juice. The serum also contains pure vitamin C — aka ascorbic acid — which offers extra antioxidant protection and works with AHAs to retexturize a complexion into smooth, glassy skin.
