How we read it
Known to clog pores. If you break out easily, this is the one to skip.
Is Glyceryl-3 Diisostearate comedogenic?
Yes. Glyceryl-3 Diisostearate 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
Listed as pore-clogging across multiple acne-safe references.
The nuance
Most relevant in leave-on products on oily, breakout-prone skin; effect can depend on the amount used.
