Before You Buy a Vitamin C Serum, Watch This | Dr. Danny Guo

📖 Full written guide with sources: https://drdannyguo.com/library/pigmentation Vitamin C is one of the most popular ingredients in skincare, but not all vitamin C serums are created equal. L-ascorbic acid, vitamin C derivatives, different concentrations, different formulations, and different price points can make choosing the right product surprisingly confusing. In this video, I break down the science behind topical vitamin C, why L-ascorbic acid is still the most researched form, and four vitamin C options I would actually recommend depending on your skin type, concerns, and budget. We cover: ✅ SkinCeuticals C E Ferulic, Phloretin CF, and Silymarin CF ✅ CeraVe Skin Renewing Vitamin C Serum ✅ Timeless 20% Vitamin C + E Ferulic Acid Serum ✅ Dr. Althea Vitamin C Boosting Serum *I SHOWED THE 20% INSTEAD OF THE 63% VITAMIN C IN THE VIDEO * I also explain the research behind combining vitamin C with vitamin E and ferulic acid, why a higher percentage doesn't automatically mean a better product, and why the best vitamin C serum ultimately depends on what you're trying to accomplish.
