You've probably heard of the benefits of getting vitamin C through food and supplements, but did you know this important antioxidant can also be applied topically? Vitamin C serums are formulated especially for the skin, and target free radicals caused by factors such as poor diet, sun exposure, and environmental exposure. Using one on a regular basis can improve skin texture, promote collagen rejuvenation, and give skin a brighter-looking appearance. Vitamin C serums have lightweight consistencies, typically come with droppers for easy application, and can be used with other skincare and makeup products. Some formulas contain additional skin-improving ingredients like hyaluronic acid and retinols. And if you are watching your budget, choose a drugstore brand that's both affordable and effective.
