A decent hydrating serum buried under aggressive brightening hype.

READ MORE

The efficacy score is 4.1/5: niacinamide appears high in the formula and supports brightening and barrier function, while glycerin, panthenol, trehalose, and sodium lactate provide credible hydration. However, the vitamin C is the weaker derivative 3-O-ethyl ascorbic acid, its concentration is undisclosed and it appears only around position 10, while the peptide blend is lower in the list and cannot justify the product's stronger anti-aging claims. The formula has no disclosed pH or concentration data, and the citrus fragrance adds irritation risk without improving treatment efficacy. The marketed peptide and vitamin C labeling is not evidence that those ingredients are present at clinically meaningful levels.
