by Remedy
Updated October 10, 2026
15% vitamin C plus antioxidants for brighter mornings; non-irritating, barrier-friendly.
What the community says
A 15% 3-O-Ethyl Ascorbic Acid serum with glycerin, squalane, panthenol, and a long antioxidant stack. It suits people who want brighter skin without the usual sting. If you hate tacky serums or prefer pure ascorbic acid, this won’t be your favorite.
What this means for you
What people love
Watch out for
- Not the cheapest vitamin C at $27
- Can feel like overkill if you only want plain vitamin C
- Pigmentation results are slower than azelaic acid for some
