#145) 5 Ethyl Ascorbic Acid Products Compared | Chemist Confessions Podcast

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. 00:00 | Vitamin C Serum Claims and Transparency 00:33 | What Is 3-O-Ethyl Ascorbic Acid? 01:16 | The Aesthetic 02:13 | Skin Type Notes 03:38 | Comparing Serum Formulations and Aging Impact 04:28 | Weird But Fascinating: The Case of ELF’s C Ferulic Dupe 05:57 | Niacinamide Levels and Additional Actives Breakdown 06:29 | Should You Trust Label Claims Without Ingredient Context? 07:25 | Numbersin's Transparency and Ingredient Ratios 09:33 | Innisfree’s Clinical Testing vs Marketing Claims Products Discussed this 2025 Podcast Season *a small portion of your purchase through these links goes to feeding a chemist. https://shopmy.us/collections/1280514 Product Shoutout: Mr. Reliable Moisturizer with 3% Ceramide Complex https://chemistconfessions.com/produc...
