WHY I LOVE IT:
One of my favorite vitamin C serums, this formula combines 10% ascorbic acid (vitamin C) with niacinamide to gently and effectively provide antioxidant protection and brightening benefits.
Please note - in my experience, this product tends to oxidize slightly more quickly than other vitamin C serums. For this reason, I recommend it for people who use vitamin C every day in order to get through the product before it fully oxidizes.
