What is a pore-clogging (comedogenic) ingredient?
A comedogenic ingredient is one that tends to block pores. When dead skin cells and oil get trapped behind a clogged pore, you get comedones — blackheads and whiteheads — and often inflamed breakouts. If you keep breaking out in the same spots no matter how well you cleanse, a comedogenic ingredient hiding in your moisturizer, sunscreen, or makeup is a common culprit.
Our comedogenic ingredient checker takes the guesswork out of reading a label. Instead of Googling ingredients one at a time, paste the whole list and get an instant, color-coded breakdown. Some people call it a pore clogger checker or non-comedogenic checker — same idea: it scans your product for pore-clogging ingredients and fungal-acne triggers so you don't have to.
The worst offenders to watch for
A handful of ingredients clog pores far more often than others. The most reliable high-risk ones include coconut oil, isopropyl myristate, cocoa butter, and wheat germ oil. Lighter, barrier-friendly swaps like squalane and hemp seed oil rate 0/5.
Frequently asked questions
What does comedogenic mean?
Comedogenic means an ingredient tends to clog pores, which can lead to comedones (blackheads and whiteheads) and breakouts. Ingredients are commonly rated on a 0–5 scale, where 0 won't clog pores and 5 is very likely to.
How does the pore-clogging ingredient checker work?
Paste any product's ingredient list and we scan it against our database of comedogenic ratings. We flag anything rated 3+ as higher-risk, note moderate (2/5) ingredients, and separately highlight fungal-acne (Malassezia) triggers.
Are comedogenic ratings scientifically exact?
No — original ratings came largely from rabbit-ear and human tests and sources sometimes disagree. Concentration and formulation matter too. Treat ratings as a helpful guide and always patch-test.
What is fungal acne and why is it flagged separately?
Fungal acne (Malassezia folliculitis) is fed by certain oils, fatty acids and esters — which is a different problem from pore-clogging. An ingredient can be non-comedogenic yet still trigger fungal acne, so we flag both.
