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 Kukui Nut Oil in the range most people, including many with acne-prone skin, tolerate well.
This rating is disputed. Credible sources land on different numbers for Kukui Nut Oil, so we publish the range (2) rather than a false single figure. When sources disagree this openly, your own experience carries real weight.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so Kukui Nut Oil near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
About Kukui Nut Oil
It is a plant- or seed-derived oil, valued for the emollient, conditioning feel it gives a formula. A light Hawaiian nut oil generally rated around 2; oxidation-prone so best used fresh.
On a label it can read as Kukui Nut Oil, Kukui Oil, Kukui Nut, Aleurites Moluccana Seed Oil — worth knowing when you scan an ingredient deck.
Kukui Nut 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 Kukui Nut 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.
