As far as buzzy skincare ingredients go, vitamin C is one of the most talked about — and for good reason. "Packed with antioxidants, vitamin C has shown to improve dull skin texture and tone, fight free radical damage, reduce signs of aging, dark spots and hyperpigmentation, hydrate, increase collagen production, brighten and provide anti-inflammatory effects," says Geeta Yadav, M.D., a board certified dermatologist and founder of Skin Science Dermatology.
"Also known as ascorbic acid and L-ascorbic acid, vitamin C provides antioxidant protection, as it uses electrons to neutralize the free radicals found on skin from environmental stressors like solar radiation and pollution," says Good Housekeeping Institute Beauty Lab chemist Danusia Wnek. Additionally, vitamin C blocks the enzyme responsible for melanin (or pigmentation) production, which means it can help brighten skin. Dr. Yadav explains that because the vitamin C is a water-soluble nutrient, it can be used topically in many different forms, including face serums.
The Good Housekeeping Institute regularly tests skincare products to find the best ones on the market. When we review vitamin C serums, we look for technology to preserve the vitamin C, unique packaging to protect against light degradation and ingredients with synergistic benefits to improve efficacy.
