Medicube Deep Vita C Glutathione Brightening Mask is a concentrated sheet mask designed to deliver an intensive treatment for dull and uneven skin. This mask is saturated with a potent essence featuring two powerful antioxidants: Vitamin C, which brightens the complexion and protects against environmental damage, and Glutathione, known for its exceptional ability to reduce hyperpigmentation and promote a clear, luminous glow. The sheet format allows for deep penetration of these active ingredients, providing a significant boost of hydration and radiance in just one use. The result is skin that looks visibly brighter, more even-toned, and full of vitality.
