Packed full of nourishing ingredients, the Oh K! mask helps to reveal a brighter-looking, dewy surface that’s even more radiant than before. Working in two simple steps to maintain freshness, the mask uses powdered Vitamin C to make sure it’s as stable as possible. This is stored in a separate sachet, which means there’s less risk of oxidisation. Vitamin C is an ingredient that can help to improve the appearance of an uneven skin tone, promoting a more uniform look across your complexion. It also works to hydrate while it protects with its antioxidant goodness, keeping environmental aggressors at bay. The mask is fully biodegradable for an eco-friendly touch.
