How we read it
Not pore-clogging
Not a pore-clogger. Considered safe for acne-prone skin.
Is Hydrogenated Polyisobutene comedogenic?
No. Hydrogenated Polyisobutene isn't considered pore-clogging, and we read it as safe to use on acne-prone skin. That doesn't make it right for everyone, but congestion isn't the thing to watch for with it.
Why we read it this way
A clean-feeling synthetic emollient often used as a mineral-oil alternative. Not on comedogenic lists.
