Oh K!’s Watermelon Sheet Mask delivers fast, visible hydration and a brighter, more even-looking complexion with watermelon fruit extract, Vitamin C (sodium ascorbyl phosphate), and hyaluronic acid (sodium hyaluronate). The lightweight serum helps plump the look of fine lines, soften dullness, and leave skin comfortably smooth after a single use. Antioxidant-rich aloe vera, glycerin, lavender, and coconut help calm irritation and support a healthier feel, while the breathable, plant-based eucalyptus fiber sheet helps keep the serum in close contact with skin. Made with a dermatologically developed Korean formula, it helps support the skin barrier to lock in moisture, reduce evaporation, and maintain a supple, soothed finish.
