About the Brand

ONE THING is a minimalist Korean skincare brand that operates on the philosophy of 'less is more,' aiming to eliminate unnecessary costs and additives to provide only the essential ingredients the skin truly needs. The brand is best known for its single-ingredient toners and extracts, such as Centella Asiatica, Houttuynia Cordata, and Niacinamide, which allow users to customize their skincare routines based on their specific, current skin concerns. By focusing on 100% plant-based, EWG Green Grade raw materials, they prioritize safety, transparency, and efficacy while maintaining an accessible price point. Their product range has expanded to include serums, creams, and DIY modeling mask packs that are free from artificial fragrances and colorings. Targeted at consumers who value rational consumption and clean beauty, ONE THING has gained popularity for its simple, aesthetic packaging and its ability to provide targeted, effective care for all skin types, including sensitive and irritated skin.
