Vitamin C and Skin Health
Vitamin C is essential for collagen synthesis and acts as an antioxidant in the skin. Topical and dietary vitamin C may help support skin texture, reduce oxidative damage, and improve the appearance of fine lines when combined with sun protection and a healthy diet. It does not reverse ageing but can support skin quality.
How Vitamin C Supports Skin
Collagen production depends on vitamin C; without it, skin may look dull and heal more slowly. As an antioxidant, vitamin C helps neutralise free radicals from UV and pollution. Some studies suggest topical vitamin C (serums) may enhance skin appearance; oral intake supports overall levels. Compare vitamin C and vitamins at iHerb.
Dosing and Sources
Dietary recommendations are 75–90 mg daily for adults; higher intakes from food and supplements are common. For skin, consistency and sun protection matter more than megadoses. Use a broad-spectrum sunscreen and include vitamin C-rich foods; add a supplement if intake is low.
