The backbone of any results-driven skincare ritual? A great Vitamin C serum—like this one that’s gentle, hydrating, and above all, effective. It’s formulated with 3-O-Ethyl Ascorbic Acid, a highly stable derivative of Vitamin C that stays on the skin longer to help visibly brighten, reduce dark spots, and smooth uneven tone. Squalane helps prevent moisture loss for a hydrated finish, while Plankton Extract helps protect against harmful oxidative stress. Use it every morning before moisturizer and SPF for a radiant, refreshed, and more youthful-looking complexion.

The Benefits:

  • Helps visibly brighten and reduce dark spots for a refreshed, youthful-looking glow.
  • Helps smooth uneven tone while delivering lightweight hydration.
  • Provides antioxidant support to help protect against harmful oxidative stress.
  • Ideal for everyday use, layering seamlessly under moisturizer or SPF.
