System Verdict
Nice concept, but the kojic acid and retinol here are used at very low, contact-time-limited levels, so you’re getting a gentle overnight hydrator with modest brightening rather than a heavy‑hitting treatment. Efficacy is driven mostly by humectants (glycerin, butylene glycol, sodium hyaluronate, glyceryl glucoside) and mid-list niacinamide for barrier and mild tone evening, while the brand-disclosed concentrations of kojic acid (~1 ppm) and turmeric (~5000 ppm) in external data indicate extremely low active strength for serious hyperpigmentation, and the peel-off film format plus low-position retinol further limit anti-aging impact. Collagen extract functions mainly as a moisturizing, marketing-friendly additive rather than a true firming active, and the overall base is more about an occlusive wrapping effect than delivering clinically-optimized doses of brightening ingredients.
