Chalogy, the company behind K-beauty brand Saturday Skin, is making a major push into the U.S. market.

“Products built on CHA Health System’s 65 years of women’s health research are really connecting with consumers,” CEO Hyo-bin Song said in a recent interview. As a subsidiary of CHA Health System, Chalogy bridges the gap between medical science and skincare.

The brand translates cellular and stem cell research into accessible skincare innovations. Its hero Yuzu Vitamin C line pairs vitamin C with yuzu oil to minimize irritation, a common issue with conventional vitamin C formulas. Following the breakout success of its Yuzu Vitamin C Sleep Mask, the company launched the Yuzu Vitamin C + Water Blossom Serum in July and plans to release the Yuzu Vitamin C Butterfly Mask this November.

The Yuzu Vitamin C Butterfly Mask introduces what Song calls the “B-zone,” a fresh take on the traditional T-zone and U-zone framework. It delivers concentrated treatment to the nose, under-eyes, and cheekbones.

Saturday Skin appeals to a broad age range, from young professionals in their mid-20s to women in their mid-40s navigating early signs of aging. Beyond its presence on Amazon and Nordstrom, the brand recently debuted at beauty giant Ulta and is testing the travel retail market at Newark Liberty and Washington Dulles airports.

“Clean beauty and vegan certification set us apart,” Song added. “We want people to feel smart about their skincare choices, getting real results without compromising their values or budget.”
