What the community says

A 15% L-ascorbic acid vitamin C serum lauded as an affordable, no-frills Skinceuticals C E Ferulic dupe with vitamin E and ferulic acid that helps tackle dullness and hyperpigmentation especially in sensitive skin, though it oxidizes fairly quickly and needs careful storage.
