How we read it
Highly comedogenic
Known to clog pores. If you break out easily, this is the one to skip.
Is Oleyl Alcohol comedogenic?
Yes. Oleyl Alcohol is a known pore-clogging ingredient, and we read it as highly comedogenic. If you're acne-prone, it's worth avoiding, especially when it sits near the top of an ingredient list.
Why we read it this way
Flagged by an acne-safe list; reports are mixed and it's not consistently called out across sources.
The nuance
Most relevant in rich leave-on products on breakout-prone skin.
One ingredient rarely tells the whole story. Run the whole label and see everything in the product at once.
