ISNTREE is a Korean clean-beauty brand founded by Jinwoo Kim, born from Korea's first skincare ingredient education blog in 2008. The name blends "island," "natural," and "tree" — reflecting the brand's commitment to eco-friendly, plant-based ingredients and honest, ingredient-first formulation. Isntree stands out for its rare transparency, publishing the exact concentration of key actives (not just "contains hyaluronic acid," but the precise percentage), pairing high-purity botanicals like green tea and mugwort with proven functional ingredients. Best known for its cult-favorite Hyaluronic Acid Toner (featuring five molecular weights of HA) and Hyaluronic Acid sun care line, Isntree is vegan, cruelty-free, and sustainability-focused — a favorite for sensitive, dehydrated skin seeking gentle, deeply hydrating, no-frills skincare backed by real ingredient data.
