System Verdict
Potent, well-built anti-aging serum with real brightening and exfoliating power, slightly undercut by high alcohol and added fragrance. Efficacy is driven by mid-listed niacinamide, a stable vitamin C derivative, a collagen-targeting peptide pair, zinc plus LHA for texture and acne, and a strong humectant/amino-acid base, but the presence of denatured alcohol near the top and fragrance components means the otherwise advanced formula won’t suit more sensitive or very dry skin.
