What a 2/5 rating means
On the comedogenic scale, a 2 is still within the non-comedogenic range that dermatologists generally consider low-risk. That places Peanut Oil in the range most people, including many with acne-prone skin, tolerate well.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so Peanut Oil near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
About Peanut Oil
It is a plant- or seed-derived oil, valued for the emollient, conditioning feel it gives a formula. A heavier nut oil rated 2/5. Uncommon in modern skincare and a potential allergen for those with peanut sensitivity.
On a label it can read as Peanut Oil, Arachis Hypogaea Oil — worth knowing when you scan an ingredient deck.
Peanut Oil in makeup and skincare
In makeup it turns up in cream blushes, tinted balms, and hydrating foundations; in skincare, in face oils and cleansing balms. Its irritancy is rated separately at 1/5, which is low.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Peanut Oil is among the fatty-acid or ester-type ingredients that community sources commonly avoid — a separate concern from its comedogenic score, and one with weaker evidence behind it.
Peanut Oil comedogenic FAQ

Is Peanut Oil pore-clogging?
It is unlikely to be. At 2/5, Peanut Oil sits in the range generally treated as non-comedogenic. Concentration still matters: an ingredient near the top of a label makes up far more of the product than one near the end. Comedogenic ratings come mostly from rabbit-ear assays and small human patch tests of the pure ingredient at high concentration, so they are a screening guide, not a prediction for your skin or a medical claim.
