What a —/5 rating means
Because no dependable rating exists, judge Papaya Seed Oil by how your own skin responds rather than by a number. The absence of a score is not the same as a zero — it simply means the ingredient has not been reliably tested on the classic comedogenic scale.
About Papaya Seed Oil
It is a plant- or seed-derived oil, valued for the emollient, conditioning feel it gives a formula. An oleic-rich oil pressed from papaya seeds, often paired in marketing with the fruit's papain enzyme even though the pressed oil carries little of it. It is named on the CLEARSTEM and AcneClinicNYC pore-clogging ingredient lists, but neither publishes a 0-5 comedogenic score for it and no Fulton-derived table we cite carries one. We therefore leave it unrated rather than invent a number — treat the listing itself as the signal.
On a label it can read as Papaya Seed Oil, Carica Papaya Seed Oil, Pawpaw Seed Oil — worth knowing when you scan an ingredient deck.
Papaya Seed 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.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Papaya Seed 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.
