Nothing you put on your face — even oil — clogs your pores and causes acne, contrary to what many skincare labels claim.

“So comedogenicity, which it refers to a product's ability to clog pores and therefore, “clog pores”, and therefore stimulate the occurrence of acne. So that's a really misunderstood topic. Like, it's probably one of the worst words ever in my field. It's really a research term, and that's really where it comes from. So it's not really, really it's like real life. Only a few things are comedogenic, per, as per, like the very complicated research that went into this like 50 years ago. You know, things like, i don’ know, coal, tar infused stuff. Almost nothing that's available on the market today, I'm going to say almost nothing, I don't know everything, but almost nothing is comedogenic at all. Whether it's Vaseline, Vaseline’s certainly not comedogenic. Vaseline, olive oil based products, oily products, oils. You know, none of these products are comedogenic, and they never have been and they never will be. So Vaseline is actually used as a negative control for comedogenesy testing. Vaseline is because we know it does not cause clogged pores.”
