Topical Vitamin C is generally safe for most skin types but may cause mild irritation or sensitivity, especially at higher concentrations or under unstable formulations. Using stable forms and gradual introduction minimizes adverse effects. It is recommended to use sunscreen alongside Vitamin C products due to increased photosensitivity.

Vitamin C (ascorbic acid) protects the skin by neutralizing free radicals generated from UV exposure and pollution, preventing oxidative damage to skin cells, lipids, and proteins. It supports collagen biosynthesis by acting as a cofactor for enzymes prolyl and lysyl hydroxylase, which stabilize collagen's triple helix structure, thereby maintaining skin firmness and elasticity. Vitamin C inhibits tyrosinase, an enzyme critical to melanin production, helping to reduce hyperpigmentation and improve skin tone. It also enhances skin repair and healing by promoting collagen formation and bolstering immune response at wound sites. Though not a sunscreen, it provides photoprotective effects by reducing UV-induced inflammation and DNA damage. Vitamin C works synergistically with other antioxidants like Vitamin E and ferulic acid for enhanced skin protection and anti-aging benefits
