What is Shark Liver Oil?
Chemically, Shark Liver Oil is a plant- or seed-derived oil. An animal oil traditionally used in ointments, named on pore-clogging lists in the moderate range.
Where Shark Liver Oil shows up
Shark Liver 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 0/5 — low, so it's unlikely to sting or sensitise on its own.
Is Shark Liver Oil bad for acne-prone skin?
Shark Liver Oil sits in the grey zone. Plenty of people tolerate it well; those who break out easily may prefer to keep it low on their ingredient lists.
Worth flagging: Shark Liver 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: Shark Liver 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.
