GLOW - Super Brightening Serum with Vitamin C + Vitamin E
Target: Brightening, anti-aging, antioxidant protectionOur Verdict
Mediocre multi-C serum overloaded with weak derivatives that won't deliver clinical brightening punch. Efficacy score of 2.8 reflects heavy reliance on inferior Vitamin C forms like Sodium Ascorbyl Phosphate (~3%), 3-O-Ethyl Ascorbic Acid, and Ascorbyl Glucoside, all requiring conversion by skin enzymes for weak activity far below pure L-ascorbic acid's 10-20% benchmark; no ferulic acid synergy with Tocopherol (trace levels), plus PEG surfactants and emulsifiers dilute stability in watery base without encapsulation. pH likely neutral (citric/sodium hydroxide buffered), suboptimal for ascorbate efficacy, and preservatives like sodium metabisulfite add oxidation risk.

Everything you need to know about our product scoring and ingredient checking tool.
What is DemythSkin and how does it work?
DemythSkin is an advanced free skincare ingredient analyzer/ ingredient checker / cosmetic ingredient scanner. Our AI reads the full INCI ingredient list of any cosmetic product and cross-references it with clinical data. We instantly break down what each ingredient does, grade the formula, and generate an easy-to-read report card so you know exactly what you are putting on your face.
Can I use this as a pore-clogging ingredients checker?
Yes. If you struggle with acne or breakouts, our tool acts as a strict non-comedogenic ingredient checker. We scan the formula for heavy waxes, comedogenic oils, and known acne triggers, flagging them instantly so you can build a truly acne-safe skincare routine.
How do the Efficacy and Safety scores work?
Every product receives a brutally honest score out of 5.0. The Efficacy Score measures if the product contains enough "Gold Standard" active ingredients to actually work. The Safety Score acts as a skincare toxicity scale, penalizing products that use harsh alcohols, volatile essential oils, or potential allergens.
Can DemythSkin help me find skincare dupes?
Absolutely. If a luxury serum gets a low efficacy score or has a terrible price-to-performance ratio, our skincare dupes finder algorithm will suggest highly-rated alternatives. We point you toward more affordable products that contain the same (or better) active ingredients.
Are these cosmetic ratings biased by brands?
Never. DemythSkin is a 100% independent clean beauty checker. We do not accept brand sponsorships to alter scores. A product's grade is determined solely by the scientific data backing its ingredient list.
