Vitamin C Serum

As far as buzzy skincare ingredients go, vitamin C is definitely one of the most popular — and for good reason. When used on a daily basis, it can help brighten dull skin, diminish acne scars, even out skin tone, hydrate skin, and protect it from pollution. Also known as ascorbic acid and L-ascorbic acid, vitamin C is a powerhouse antioxidant found in many skincare products such as serums, moisturizers, and face masks. It uses electrons to neutralize free radicals (a.k.a. pollution) lingering on the surface of the skin. Additionally, it blocks the enzyme responsible for melanin (or pigmentation) production, which means it brightens skin and prevents dark spots.
