What a 3/5 rating means
On the comedogenic scale, a 3 is the moderate midpoint: tolerated by many, a possible trigger for congestion-prone skin. That puts Corn Oil squarely in the judgement-call zone, where your skin type and the product's formula decide the outcome.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so Corn Oil near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
About Corn Oil
It is a plant- or seed-derived oil, valued for the emollient, conditioning feel it gives a formula. An inexpensive food-grade oil rated 3/5; more often a filler than a hero ingredient in skincare.
On a label it can read as Corn Oil, Zea Mays Oil, Zea Mays, Corn — worth knowing when you scan an ingredient deck.
Corn 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 0/5, which is low.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Corn 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.
Lower-rated alternatives to Corn Oil
