Pore Clogging Checker

Pore Clogging Checker is a free web tool that instantly identifies pore-clogging (comedogenic) ingredients in any skincare product. Paste an ingredient list, upload a photo of the label, or search 2,000+ ingredients - each one is rated low, moderate, or high risk based on published dermatology research, including the classic Fulton comedogenicity scale. Built for acne-prone skin: no signup, works in 6 languages, and covers moisturizers, sunscreens, cleansers, and makeup. Stop guessing which ingredients clog pores - check before you buy.
