Pore-Clogging or Not?

Many people are very cautious about whether the cosmetic products that they use would clog their pores or not. Although, there are certain aspects you should consider when it comes to pore-clogging aka comedogenic ingredients:

  • comedogenic ingredients are "likely" to cause and aggravate acne but it doesn't definitely cause that so you shouldn't rule out those ingredients completely
  • it would take the ingredients practically an entire day to clog up your pores so practice good make-up removal routine to avoid this problem. Thus, you should definitely not sleep in with your make-up on
  • comedogenic ingredients when of high quality would not be too likely to clog your pores. It is recommended to use approved skin care products as there would be better quality control in the ingredients

Here's a list of the level of comedogenicity for ingredients that you may find in your cosmetics:

you write squalene in both highly comedogenic and non comedogenic? Can you clarify this for me?

From what I've read, squalene itself as well as squalene hydroxide are mildly comedogenic. However, squalene peroxide is highly comedogenic.

I hope that clarifies it.

Thanks for pointing that out to me. I'll make the changes in the post.

However, I only ask that you'd take a look at the FAQ page before asking a question.

Thanks a bunch!
