How it works

The Ultimate S Serum 50ml is Sulwhasoo's take on the serum step. On its own ingredient list, Dimethicone sits at position 4 of 63 on the ingredient list, a silicone that shapes a smooth, quick-setting glide rather than a heavier lotion feel. Sodium Hyaluronate sits at position 29 of 63 on the ingredient list, a salt form of hyaluronic acid that holds water at the skin's surface for a plumper feel. Beta-Glucan sits at position 33 of 63 on the ingredient list, an oat or yeast-derived polysaccharide used to support a calmer, more resilient-feeling barrier. Panax Ginseng Berry Extract sits at position 50 of 63 on the ingredient list, Korean ginseng root extract, a traditional hanbang ingredient valued in Korean formulation for its restorative reputation. Sulwhasoo is a heritage Korean luxury house built around fermented Korean red ginseng and hanbang (traditional herbal) formulation, and this formula carries that character through serum format rather than a stripped-down version of it. It belongs to the serum step, applied after toner and before moisturizer, and what it does for skin is best judged after it has had time to settle in, rather than by a single application. This is the Korean-market formula of the ultimate s serum 50ml, the version sold on shelves in Korea rather than one reworked for a different market.
