Comedogenic Ratings

comedogenic /ˌkɒmɪdə(ʊ)ˈdʒɛnɪk/

adjective

1. tending to cause blackheads by blocking the pores of the skin.

Noncomedogenic is a term used to describe cosmetic products that are formulated in such a way that they are not likely to cause pore blockages (comedones) and breakouts. It's mainly used to describe skincare products and cosmetics.

A product labeled noncomedogenic does not contain ingredients that are known to clog the pores. If you have acne, blackheads, or are prone to clogged pores, using noncomedogenic skincare products and cosmetics might help reduce the number of breakouts you get. However it doesn’t guarantee anything. Just because a product is labeled noncomedogenic does not mean it won’t cause comedones, it just means it's less likely. Everyone's skin is different and reacts differently to every product.

Even noncomedogenic products can clog pores in certain people. So, if you're noticing lots more blackheads, whiteheads, and bumpiness after using a certain product, even if it is labeled noncomedogenic, you might want to stop using it and see if the breakouts improve.

Also, remember that simply because a product is not labeled noncomedogenic doesn't automatically mean that it will clog your pores. If you've been using a product for years and you love the way it works for your skin, there is no reason to ditch it if it doesn't carry the noncomedogenic label.

The feel of a product isn't a good indication of whether it is noncomedogenic or not. There are some very emollient, greasy-feeling products that don't contain comedogenic ingredients, and very light products that do.

Know your ingredients! This list below displays a rating comedogenic ingredients- in other words a rating for the tendency of the ingredients to clog pores, which may cause acne. The goal is to stay below 2.

The ingredients are rated on a comedogenicity scale from zero to five. A score of zero means no comedones developed so it won't clog pores. A score of five means there's a high likelihood it will cause comedones. Many lists vary in rating however this is the best we can compile. The below list has been derived and compiled from various sources, including the Journal of American Academy of Dermatology.
