Benefits of Vitamin C Serum  This serum has many benefits that made it one of the most popular products recently. These benefits include: Sun protection Vitamin C is an antioxidant; this means that it reduces the damage that free radicals can cause the body. Free radicals are molecules that cause infections. According to the Linus Pauling Institute at Oregon State University, some of the antioxidant effects that a vitamin C serum causes on the skin include: Reducing early cell death. Reducing the release of cytokines, which are inflammatory compounds. Reducing damage from exposure to UV rays. Although no other products should be used to replace sunscreen, applying topical vitamin C may help protect against the harmful effects of the sun. Preventing premature aging  Vitamin C cannot reverse the appearance of wrinkles that develop naturally over time, however the Vitamin C serum can help reduce premature aging by protecting the skin from the early wrinkles that sun exposure can cause, and it also helps reduce early wrinkles By stimulating collagen growth (collagen is a protein that provides structure and elasticity to the skin). In addition, a small-scale study found that using a 5% vitamin C solution for 6 months helped increase the thickness of the skin compared to a placebo (or placebo) solution. Thicker collagen-rich skin is less prone to wrinkling than thin skin. Although the study recorded only 60 participants, it did show promising results in supporting vitamin C as a collagen stimulator. Unification of skin color Some people use vitamin C serum to treat hyperpigmentation (areas of the skin that appear darker than the surrounding area). Sun exposure or hormonal changes associated with aging usually cause these dark areas. Researchers believe that vitamin C may help reduce melanin production, according to the Linus Pauling Institute at Oregon State University (melanin is a pigment responsible for the dark appearance of highly pigmented areas, and by reducing its production the skin may appear lighter and less pigmented).
