What it is
This medicated whitening*1 serum, based on a beauty treatment concept, delivers firm, radiant, moisturized, and translucent skin. It contains the whitening*1 active ingredient "glycosylated stable vitamin C derivative" that prevents the formation of bothersome spots and freckles, the translucent care ingredient*2 "glutathione" that provides moisture, and "G Circulate CPX*3" that circulates moisture to every corner of the stratum corneum, all concentrated in a smooth emulsion base. With two approaches, "nourishing" and "circulating," it refines skin texture and brings out outstanding translucency. Even dry adult skin becomes moist and radiant like a white pearl. .
