Mad Hippie Vitamin C Serum
Updated Nov 8, 2026 · Top Vitamin C Serum for face
Best for Sensitive or acne-prone skin that wants vitamin C without the sting of L-ascorbic acid.
A stable vitamin C serum that uses sodium ascorbyl phosphate, not L-ascorbic acid. Mad Hippie says SAP stays potent and is less likely to turn brown, and the bottle also has hyaluronic acid, vitamin E, and ferulic acid. The amber color is the formula on day one, not a sign it has oxidized. The brand does not print the SAP percentage, so it is not comparable to a labeled 20 percent ascorbic acid serum. Use it in the morning if Timeless burns. It will not match a fresh ascorbic acid serum for brightening. Wear sunscreen after it.
