What it is The TIRTIR Matcha Dual Serum is an advanced, bi-phase clinical treatment engineered to provide an instant moisture surge and intensive calming care for sensitive, uneven, or flushed skin tones. Powered by an innovative 2:8 cream-to-ampoule dual-layer synergy and advanced formulation tech, this mildly acidic serum comfortably delivers two complementary cosmetic benefits in one single shake. The nutrient-dense formula melts rapidly into the skin with a non-sticky finish, helping to visibly minimize skin blotches, strengthen the look of the skin barrier, and restore a clear, uniform, and radiant "glass-skin" complexion.   Product Size: 50ml / 1.69 fl. oz.   Product From: South Korea
