Vitamin C, Decoded: What the Glow Really Comes From

Not all vitamin C is created equal. Here is what makes a serum stable, effective and worth your shelf space.

Vitamin C is one of the most researched ingredients in skincare — and one of the most misunderstood.

## Why it matters As a potent antioxidant, vitamin C neutralises free radicals from UV exposure and pollution, helps fade uneven pigmentation, and supports a brighter, more even tone over time.

## Stability is everything Pure L-ascorbic acid is effective but notoriously unstable — it oxidises quickly. Newer derivatives like THD ascorbate are gentler, oil-soluble and far more stable, which means your serum stays active for longer.

## Pair it wisely Vitamin C loves company. Ferulic acid and vitamin E boost its stability and effectiveness. Always follow with SPF in the morning for compounding protection.

## What to expect Give it six to eight weeks. The glow is real, but it is cumulative — consistency beats intensity every time.
