Vitamin C is the #1 topical antioxidant for skin — it protects against sun damage, fades dark spots, brightens dull skin, and boosts collagen production. Dermatologists consider it essential alongside sunscreen. Yet most men have never used one. If you add only one serum to your routine, make it vitamin C.

How to Use Vitamin C
When: Morning only — vitamin C protects against daytime UV and pollution damage. Order: Cleanse → Vitamin C serum (wait 1-2 min to absorb) → Moisturizer → Sunscreen. Don’t mix with: retinol (use retinol at night instead), AHAs/BHAs (alternate days), benzoyl peroxide (it inactivates vitamin C). Storage: L-ascorbic acid (pure vitamin C) oxidizes quickly. If your serum turns dark brown/orange, it’s degraded — replace it. Store in a cool, dark place.
