I Ranked Dermatologist & Influencer Vitamin C Serums (As a Cosmetic Chemist)

I Reviewed 5 Influencer Vitamin C Serums as a Cosmetic Chemist | Doctor Brands vs. Influencer Brands As a cosmetic chemist, I pulled the full ingredient lists of 6 vitamin C serums from creators and doctors you actually follow — and ranked them on formulation science, not branding or aesthetics. What we cover: Dr. Sam Bunting's Vitamin C NAD+ Serum: two smart vitamin C forms, ferulic acid, and the NAD+ claim — what the science actually says Dr. Muneeb Shah's Remedy 15% Vitamin C: one of the most well-rounded antioxidant stacks I've reviewed, and why the supporting cast matters Dr. Sam Ellis's Prequel Lucent 15%: pure L ascorbic acid, 14 ingredients, the most scientifically rigorous formula in the video — with one real caveat Summer Fridays Vitamin C Serum: the fragrance cocktail inside a brightening serum that should give you pause, especially on melanin-rich skin Naturium Vitamin C Complex Serum: why I've personally used this up — and the pH issue that limits what the ascorbic acid can actually do Naturium Super Serum+: vitamin C + retinol + niacinamide + salicylic acid in one bottle — ambitious or overcrowded? Chapters: 0:00 Hook — can you trust the creators you follow to formulate well? 0:20 My ranking criteria — form, concentration, stability, and what's getting in the way 1:07 Dr. Sam Bunting — THDA + ascorbyl glucoside, ferulic acid, and the NAD+ claim 2:26 Dr. Muneeb Shah — 3-O-ethyl ascorbic acid and an impressive antioxidant stack 3:41 Dr. Sam Ellis — pure L ascorbic acid, 14 ingredients, and who this is actually for 5:04 Influencer brands — Summer Fridays by Marianna Hewitt 6:13 Naturium Vitamin C Complex — legit forms, gentle formula, pH trade-off explained 7:09 Naturium Super Serum+ — too many actives, weakest retinoid, vitamin C too low to lead 7:50 Final rankings — doctor brands vs. influencer brands ⬇️ Drop your vitamin C questions below 🔔 Subscribe for chemist reads made for us #VitaminCSerum #CosmeticChemist #SkincareIngredients #MelaninRichSkin #InfluencerSkincare #LAscorbicAcid #SkincareScience #HyperpigmentationTreatment #DrSamEllis #Naturium #SummerFridays #SkincareForDarkSkin
