In this episode, we put five popular vitamin C serums featuring 3-o-ethyl ascorbic acid to the test: Beauty of Joseon Light on Serum, Elf C+E+Feruic Acid Serum, Olay Vitamin C Brightening Serum, Innisfree Green Tean Enzyme Vitamin C, and Numbuz:n 5+. This is a wild category of products. Unlike the CE Ferulic dupes, the range is far and wide in between! From texture critiques (why so sticky, Elf?) to actives breakdown, we decode the labels and share which formulas we’d choose — and which ones barely count as a vitamin C serum at all.
