Serums typically contain antioxidants that help combat free radical damage. They may also contain anti-aging ingredients like retinols and peptides, which stimulate collagen production. Because they penetrate deeply into the skin, these products are excellent for hydrating dry skin. It's recommended to use them after cleansing, and they can be applied under moisturizer to nourish the skin while you sleep.
