How we read it
Known to clog pores. If you break out easily, this is the one to skip.
Is Myreth-3 Myristate comedogenic?
Yes. Myreth-3 Myristate 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. The acne ingredient checker reads everything in a product at once, the pore-clogging ingredients list has the rest of what we flag, and there is more on what comedogenic means. Also in the guides: What causes acne.
