Do you know what comedogenic means? The Skin Nerd explains why you need to know

Is it just a marketing term, or can certain ingredients clog your pores?

Some products you're using may be comedogenic. Keep an eye on the ingredients in your skin care. 

If you read about skincare and the type of skincare you should be using, you’ve come across the phrases “comedogenic” or “non-comedogenic”. Even if you’re not an avid skin content viewer, in the good old days of browsing the pharmacy aisles while waiting for your prescription, you’ve certainly seen it! But what does it mean, and does it matter?

Comedogenic comes from the word “comedone”, the nerdie terminology for a whitehead, blackhead, or a small, headless bump. Whiteheads are known as closed comedones, where the pore is fully plugged and blackheads are known as open comedones, as you can see their insides, essentially. Comedogenic is widely accepted to describe a substance that can contribute to clogged pores and potentially comedones.
