What the community says

The original gold-standard 15% L-ascorbic acid + vitamin E + ferulic acid serum that remains a go-to for brightening and hyperpigmentation but is infamous for its steep price and sticky, slightly greasy finish on oily skin.

What people love

  • Proven 15% L-ascorbic acid concentration with patented antioxidant combo
  • Airless pump packaging that slows oxidation and preserves potency
  • Clinically shown to visibly brighten skin and reduce dark spots

Watch out for

  • Extremely expensive compared to effective dupes like Timeless or Geek & Gorgeous
  • Can cause redness and irritation, especially on sensitive skin or those prone to eczema
  • Sticky and heavy feel leaves a shiny/dewy finish that doesn't suit oily or combination skin
