Pore Clogging Checker od 雪剑20

Check any skincare or cosmetic ingredient list for pore-clogging (comedogenic) ingredients — anywhere on the web, in seconds.

WHAT IT DOES
• Paste an ingredient list into the popup and get an instant 0–5 comedogenic rating for each ingredient, with clear color-coded verdicts: green (clear), amber (low risk), red (high risk of clogging pores).
• On any product page, select an ingredient list, right-click and choose "Check pore-clogging ingredients" to get a verdict card right next to the text.

SCIENCE-BASED RATINGS
• 239-ingredient database built on the Fulton 1989 rabbit-ear assay plus classic acne-clinic pore-clogging lists.
• 0–5 ratings with irritancy notes, alias matching (INCI + common names), and fuzzy matching for close spellings.

PRIVATE BY DESIGN
• 100% local analysis in your browser — no accounts, no tracking, works offline. Nothing you paste or select is ever uploaded.
• Zero setup: install and go. The only stored state is your last checked list and the UI language (English / 中文).

GOING DEEPER
The extension checks the first 5 ingredients per scan. For unlimited full-list checks plus image & PDF reports, the companion site porecloggingchecker.app has you covered — your list is copied automatically when you hop over.

Great for acne-prone skin: screen moisturizers, sunscreens, cleansers and makeup for pore-clogging ingredients before you buy.
