The Oh K! Watermelon Sheet Mask provides a revitalizing burst of hydration for brighter, more radiant skin. This biodegradable, plant-based sheet mask is soaked in a potent serum formulated with watermelon extract, hyaluronic acid, and vitamin C. Watermelon extract delivers antioxidant-rich moisture, hyaluronic acid draws hydration from the air to plump the skin, and vitamin C helps to brighten and even skin tone. The eucalyptus fiber mask creates a barrier to ensure maximum absorption of the super-hydrating ingredients, leaving your skin feeling refreshed and luminous in just 10-20 minutes.
