APLB Glutathione Niacinamide Sheet Mask is an advanced Korean skincare sheet mask designed to provide deep hydration, soothing care, and brightening for all skin types, including sensitive skin. Enriched with 13.7% active ingredients, the mask combines glutathione and niacinamide to enhance skin radiance, improve elasticity, and promote a smoother, healthier-looking complexion. The formulation includes glutathione, a potent antioxidant, which helps neutralize free radicals and supports brightening effects, while niacinamide works to even skin tone and enhance overall clarity. The addition of Centella Asiatica extract, at 13.5%, helps calm irritation and strengthen the skin's natural barrier, making it ideal for sensitive or reactive skin. Together, these actives provide a multifunctional approach, addressing dullness, dehydration, and minor discomfort caused by environmental stressors. The ultra-adhesive cellulose sheet ensures close contact with the skin, allowing rapid and effective delivery of active ingredients. Microfluidizer technology creates nano-sized glutathione particles for deeper penetration, improving absorption and skin adhesion. The mask's weakly acidic pH closely matches healthy skin, reducing the risk of irritation while maximizing comfort and effectiveness. Its non-sticky, nutrient-rich essence provides full hydration without leaving a heavy residue, leaving the skin soft, supple, and refreshed. All ingredients are EWG green grade and the formula is free from 10 harmful substances, including animal-derived ingredients, pigments, fragrance, polyacrylamide, and silicone, making it safe for sensitive skin.
