Best Vitamin C Serum in India: Fading Hyperpigmentation & Tan

Understanding Vitamin C: L-Ascorbic Acid vs Derivatives

Vitamin C is a powerful antioxidant that neutralizes free radicals, boosts collagen synthesis, and inhibits melanin production. However, pure Vitamin C (L-Ascorbic Acid) is highly unstable, oxidizing quickly when exposed to light, air, and heat.

For the hot Indian climate, stable derivatives like Ethyl Ascorbic Acid (EAA) or Sodium Ascorbyl Phosphate (SAP) are often preferred because they do not oxidize easily and are less likely to cause stinging or redness.

How to Keep Your Vitamin C Serum Active

Store your serum in a dark, cool drawer rather than on your bathroom shelf. Always apply it in the morning followed by a broad-spectrum SPF 50 sunscreen. Vitamin C and sunscreen work synergistically, providing double the defense against UV-induced pigmentation.
