How we read it

Highly comedogenic

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

Is Isopropyl Isodecanoate comedogenic?

Yes. Isopropyl Isodecanoate 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

A fatty ester used for slip and a silky finish; esters in this family are commonly reported to congest acne-prone skin.

The nuance

Effect depends on concentration and the rest of the formula; usually more of a concern in rich, leave-on products.

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