The Vitamin C Story

One ingredient. Three ways to glow.

About the ingredient

  • Vitamin C (ascorbic acid) is one of the most widely used antioxidants in skincare.
  • It's known for helping skin look brighter and more even when used consistently.
  • Pure ascorbic acid is sensitive to water and air, so how a formula is packaged and used matters.

Creative visualization

Cleanse

From fine powder to cloud-soft foam

Pour the fine powder into a wet palm, add a few drops of water and rub — it turns into a dense, creamy foam in seconds.

Creative visualization

Mask

Essence you can feel working

A soft, well-soaked sheet delivers a light, watery essence. After removing the mask, pat the remaining essence into skin until absorbed.

Creative visualization

Brighten

A silky ampoule that sinks in

A few drops spread easily across the face and absorb quickly, leaving skin fresh rather than tacky — so the next step goes on smoothly.
