15% L-ascorbic acid dupe that brightens fast and costs ten bucks.
What the community says
A 15% L-ascorbic acid serum with ferulic acid, tocopherol, panthenol, and sodium hyaluronate that people buy as a SkinCeuticals-style dupe. It suits dull, uneven, or post-acne-mark skin. The catch is stickiness, pilling, and occasional burning.
