What Are Comedogenic Ingredients?
Comedogenic ingredients are substances that have a tendency to clog pores, which can lead to acne breakouts. The term comes from "comedones," the medical name for clogged pores (blackheads and whiteheads).
These ingredients form a barrier on the skin that can trap oil, dead skin cells, and bacteria inside your pores, potentially causing inflammation and acne.

Understanding Comedogenic Ratings
Most Common Pore-Clogging Ingredients

Despite being natural, coconut oil is highly comedogenic and can trigger breakouts in acne-prone skin.
Isopropyl Myristate

Lanolin
Wool-derived ingredient that's very occlusive and can easily clog pores.
Algae Extract
Often found in "natural" products but highly comedogenic.
Frequently Asked Questions
Are all oils comedogenic?
No! Some oils like jojoba oil, squalane, and mineral oil are non-comedogenic. However, coconut oil, wheat germ oil, and linseed oil are highly comedogenic.
Does "non-comedogenic" on the label mean it's safe?
Not necessarily. The term "non-comedogenic" is not regulated, so companies can use it even if their products contain pore-clogging ingredients. Always check the ingredients list yourself.
What rating should I avoid?
If you're acne-prone, try to avoid ingredients rated 3-5, especially if they appear in the first 7 ingredients (which means they're present in higher concentrations).
Can non-comedogenic products still cause acne?
Yes. Acne can be caused by many factors including hormones, bacteria, stress, and diet. However, removing comedogenic products from your routine can significantly help.
How accurate is this checker?
This tool is based on scientific research including the landmark Fulton (1989) study and data from Acne.org. However, individual reactions vary - what clogs pores for one person may be fine for another.
Should I check my shampoo and conditioner too?
Yes! Hair products can transfer to your face, back, and chest, causing breakouts. Check everything that might touch your skin.
