Brandefy
Clinical Vit C + E + Ferulic Defend Serum (1 fl oz)
Amazon page snapshot accessed 2026-10-12. Prices and ratings are not live; check the listing for updates.
Best for: A classic vitamin C, E and ferulic acid serum at a lower price than prestige versions
Our take
A morning antioxidant serum built on the best-studied vitamin C combination: 15% L-ascorbic acid, vitamin E and 0.5% ferulic acid. The label lists those percentages plainly, and the listing states a pH below 4, the acidic range L-ascorbic acid needs to be effective. Brandefy positions it as a lower-cost take on prestige serums with the same recipe. Used daily under sunscreen, this kind of serum can help with dullness and uneven tone over a few months. The listing notes a light medicinal scent from the ferulic acid, which is normal. L-ascorbic acid oxidizes with air and light, so keep it closed, cool and dark, and replace it if it turns dark orange. It can tingle at first; patch-test if your skin is sensitive.
