Shiseido's first skincare innovation, Eudermine Activating Essence infuses skin with two types of hyaluronic acid for 24 hours of deep hydration while targeting dark spots with vitamin C. Created in 1897 and rooted in Japanese beauty rituals, Eudermine was a favorite of geishas, who used it to protect skin under heavy makeup. With a double dose of hyaluronic acid, the ultra-hydrating formula drenches skin in moisture, while Vitamin C brightens and evens complexion. The lightweight texture revitalizes, nourishes and softens skin, an essential step in any skincare routine.
