A medicated whitening serum that creates a clear luster
The smooth and highly penetrating serum softly loosens the skin as if after a massage, and delivers the whitening active ingredient 4MSK deep into the stratum corneum. It suppresses the production of melanin, leaving your skin with a polished glow and a clear, radiant complexion.
4MSK (potassium salt of 4-methoxysalicylic acid)
Whitening is the process of suppressing melanin production and preventing sun spots and freckles caused by exposure to the sun.
