The efficacy score is driven by a solid humectant stack—glycerin, propanediol, sodium PCA, panthenol, and multiple forms of hyaluronic acid—plus niacinamide high enough in the list to plausibly contribute to barrier support and mild brightening; it loses points because it is still fundamentally a water-based hydrator with no high-potency treatment active, and the formula’s main strength is comfort and moisture retention rather than transformative correction.
