How we read it

Highly comedogenic

Known to clog pores. If you break out easily, this is the one to skip.

Is Isostearyl Isostearate comedogenic?

Yes. Isostearyl Isostearate 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.

One ingredient rarely tells the whole story. Run the whole label and see everything in the product at once.
