ISOI ("I'm So Intelligent") is a South Korean clean-beauty brand founded in 2009 by Jinmin Lee, who set out to create effective, safe skincare for her own sensitive, acne-prone skin. ISOI is best known for its signature Bulgarian Rose Otto — high-grade, steam-distilled Rosa Damascena oil sourced from Bulgaria's Rose Valley, with each gram derived from around 3,000 handpicked roses — used across its cult-favorite Bulgarian Rose Brightening line, including the long-standing Olive Young bestseller, the Bulgarian Rose Blemish Care Up Serum. The brand also incorporates PDRN in its repair-focused lines for post-procedure or stressed skin. EWG-verified, dermatologist-tested, and free of harmful chemicals, ISOI targets "intelligent consumers" who scrutinize ingredient lists, offering premium, botanical-first, results-driven skincare for sensitive skin.
