Niacinamide is well-positioned as a meaningful brightening and barrier-supporting active, supported by humectants like glycerin, butylene glycol, and sodium hyaluronate; however, the high placement of denatured alcohol and reliance on weakly evidenced marketing extracts (caviar, gold, plant stem cells) limit true treatment impact, and the vitamin C derivatives plus peptide are likely at low, secondary concentrations that cannot justify a high-performance score in this watery, fragranced base.
