What the community says

A 15% L-ascorbic acid serum with vitamin E and ferulic acid that’s hailed as a budget-friendly dupe of pricier antioxidants, appreciated for fading hyperpigmentation and brightening dull complexions but requires cool storage to avoid oxidation.

What people love

  • Holy grail Skinceuticals C E Ferulic dupe at a fraction of the cost
  • Clear, straightforward formula without fragrance or alcohol, suitable for sensitive skin
  • Includes antioxidant trio (vitamin C, E, ferulic acid) known to boost stability and efficacy

Watch out for

  • Oxidizes quickly unless decanted and refrigerated, often arriving clear but can degrade to brown or orange hues
  • Can be irritating or sensitizing due to pure ascorbic acid concentration, especially without proper sunscreen usage
  • Some users note increased lightening that can make under-eye circles and redness more apparent
