Green Tangerine Vita C Serum Mask is an effective skin brightening mask that contains green tangerine extract collected from Jeju Island. The mask brightens patches of pigment on the skin, marks left by acne and other hyperpigmentation that may make the skin look older than it is. The mask contains niacinamide and vitamin C, which diminish pigment spots and help balance the skin: niacinamide balances sebum secretion and vitamin C enhances the production of collagen, making the skin look healthy and bright. The mask enriched with Vita C serum also contains a lot of hyaluronic acid, which fills the skin with moisture, making the skin look much smoother and plumper.
