What is Neem Oil?
Chemically, Neem Oil (INCI name: Melia Azadirachta Seed Oil) is a plant- or seed-derived oil. An antimicrobial oil used in acne folklore; usually placed around 1-2. Strong odour and heavy texture.
You may see it on labels as Neem Oil, Melia Azadirachta Seed Oil, Azadirachta Indica Seed Oil, so it can hide under more than one name in an ingredient list.
Where Neem Oil shows up
Neem 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 Neem Oil bad for acne-prone skin?
That low score makes Neem Oil a reasonable choice even for acne-prone skin. As always, individual reactions vary, but it is not a likely cause of clogged pores.
Worth flagging: Neem Oil's rating is disputed. Credible sources land on different numbers, which is why we show a range rather than a single score — and why your own experience is the best tiebreaker.
Note for fungal-acne (malassezia) sufferers: Neem 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.
