In the 1970s, scientists observed that elderly Japanese sake brewers had remarkably youthful hands. Their hands had been constantly immersed in fermented sake “mash,” which sparked research into fermentation, leading to the discovery of a naturally derived liquid that revolutionized skincare.

SK-II’s proprietary ingredient, PITERA™, was chosen from over 350 alternatives. Packed with over 50 micronutrients, it improves the skin's natural regeneration process, addressing visible fine lines, wrinkles, dark spots, and dullness for radiant, youthful skin. PITERA™ is exclusive to SK-II and cannot be synthetically replicated.

Crafted in Shiga, Japan, SK-II seamlessly blends traditional Japanese craftsmanship with cutting-edge science. All our products are produced in Japan to this day and embody a commitment to purity, precision, and the highest standards of luxury skincare. Backed by decades of research and advanced technology, SK-II continually innovates to deliver proven, transformative results.
