When Seulgi sat down to get her makeup done, she was clutching a tube of R’SHYT Ferfree White Milky Crystal Balm Cream, which she applied as a primer before the makeup artist went to work. Curious as to what could be inside the worst English-language packaging I’ve ever seen, I asked what this “R’SHYT” is all about. “I bought it online, and I don’t know. It just makes my skin look better,” Seulgi replied.Digging deeper, I found that R’SHYT is a small cosmetics brand headquartered north of Seoul, kind of close to the North Korean border. While most brands have offices in the swanky Gangnam area of Seoul, R’SHYT is located in a country-mouse location called Goyang. Ferfree is its fermented skin-care label, and the White Milky Cream promises to improve “the tired darken skin to a bright and radiant one.”What the brand lacks in English skills, it makes up for in science. The Ferfree line centers around RF2SX, an herbal compound produced from the fermentation of Korean botanicals and the super-probiotic Lactobacillus plantarum. It contains ginseng, bamboo shoot, sponge gourd, licorice, deer antler (yikes), arrowroot, beans, mulberry root, and the list goes on. This cream, which contains this fermented compound, promises to nourish skin, improve its resilience, relieve redness, brighten, moisturize, and diminish wrinkles.From the first time I used this cream, I had to agree with Seulgi. My skin just looked better. In function, this milky cream works like a primer, and when it comes to primers, less is really more. The texture is pretty similar to sunscreen, but odorless. Because I only apply a light layer, I didn’t find it super-moisturizing or ground-breakingly nourishing. What it did do is cover my face in an inexplicably flattering veil, so my skin looked like my skin — only better.Like many smaller cosmetics companies at the lower rungs of the Korean beauty jungle, R’SHYT made a name for itself in the highly-competitive arena of the country’s home-shopping network. In 2013, it sold 200,000 Ferfree White Milky Creams just through Internet sales. And, in 2015, Seulgi used it.Ferfree White Milky Crystal Balm Cream, $21.25, available on
