What is Peanut Oil?
Chemically, Peanut Oil (INCI name: Arachis Hypogaea Oil) is a plant- or seed-derived oil. A heavier nut oil rated 2/5. Uncommon in modern skincare and a potential allergen for those with peanut sensitivity.
You may see it on labels as Peanut Oil, Arachis Hypogaea Oil, so it can hide under more than one name in an ingredient list.
Where Peanut Oil shows up
Peanut Oil is commonly formulated into facial oils, cleansing balms, moisturisers, hair products, and many products marketed as natural. Separately from clogging, its irritancy is rated 1/5 — low, so it's unlikely to sting or sensitise on its own.
Is Peanut Oil bad for acne-prone skin?
That low score makes Peanut Oil a reasonable choice even for acne-prone skin. As always, individual reactions vary, but it is not a likely cause of clogged pores.
Note for fungal-acne (malassezia) sufferers: Peanut Oil is commonly avoided in fungal-acne routines, since it falls into the fatty-acid or ester families the yeast can feed on. The evidence there is looser than for comedogenicity — see our fungal-acne checker for context.
