2024 CBA JudgeThis water-based serum leaves skin awash in vitamin C and moisture-boosting hyaluronic acid, aloe, and glycerin. Its light weight makes it ideal for layering under oils, creams— and your favorite SPF for day wear. I love that it disappears under my other skin care products but still treats my skin with vitamin C.

2024 CBA JudgeThis is a simple vitamin c serum. You could probably find better ones out there for the same price.

2024 CBA JudgeThe ingredients in Dr. Louie's Vitamin C serum are pure and simple making it great if you have sensitive skin like me. I've always found vitamin C serums too harsh for my sensitive skin, but not this serum!
