In just one night, you'll regain the elasticity and brightness lost during a whole week. Believe us, you'll start to see results right from the first use. This is why this night mask is one of Klairs' best sellers and we couldn't wait to bring it from Korea! Its secret: a super-high percentage of vitamin E that keeps skin hydrated, youthful-looking, smooth and radiant. It melts when it touches the skin, and adopts an oil-like texture, keeping your skin hydrated for a full 8 hours and promoting cellular regeneration and oxygenation. If you're already a fan of the brand, you might be wondering: the effects of this mask are multiplied when combined with the Klairs Freshly Juiced Vitamin C serum. The night mask acts like a shield that prevents the vitamin C from oxidising.
