Tatcha Luminous Deep Hydration Lifting Mask Box of 4 NEW in BOX. This biocellulose treatment mask contains an anti-aging serum—a proprietary complex of Okinawa Red Algae and natural hyaluronic acid—that delivers an instantly hydrated, firmed and lifted appearance. Each mask is distilled from an entire coconut into an ultra-concentrated mask, forming an occlusive layer on the skin and allowing for 53% more efficient penetration of its serum than paper masks. The pure and powerful active ingredients are able to quickly saturate the skin, infusing the skin with revitalizing moisture and plumping away the appearance of fine lines. Tatcha's signature Hadasei-3™: a trio of anti-aging Japanese superfoods born from nourishing Green Tea, Rice and Algae, restores a healthy-looking, youthful radiance.
