  • Lightweight texture absorbs quickly without leaving residue under makeup or other products

Hero ingredients

  • Ascorbic Acid (23%): Pure vitamin C that brightens skin and fades dark spots through consistent use.
  • Propanediol & 1,2-Hexanediol: Humectants that draw moisture into the skin, keeping it hydrated and smooth.
  • Panthenol: Soothes and conditions the skin barrier to counterbalance vitamin C's potency.

How to use

Unlock the dropper by twisting the cap and remove it from the bottle. Dispense 2-3 drops into your palm and gently pat the serum onto clean skin until fully absorbed. Always follow with sunscreen during the day, as vitamin C increases sun sensitivity and you'll want UV protection to protect your brightening gains.
