System Verdict
Potent brightening serum with real actives, but the high alcohol and heavy fragrance make it a risky choice for sensitive skin. The efficacy hinges on a meaningful 3.5% niacinamide backbone plus a stabilized vitamin C derivative (3-O-ethyl ascorbic acid) and adjunct brightener phenylethyl resorcinol, supported by salicylic acid for texture and pore refinement; however, the alcohol-forward base and multiple fragrance allergens lower the overall usability window despite a strong active stack.
