What a 4/5 rating means
On the comedogenic scale, a 4 is in the high-risk band, with a real likelihood of clogging pores on acne-prone skin. That means Flaxseed Oil deserves attention if you break out easily, especially when it appears high on an ingredient list.
This rating is disputed. Credible sources land on different numbers for Flaxseed Oil, so we publish the range (4) 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 Flaxseed Oil near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
About Flaxseed Oil
It is a plant- or seed-derived oil, valued for the emollient, conditioning feel it gives a formula. A fragile omega-3 oil that oxidises quickly; commonly rated around 4 and generally kept out of leave-on facial products.
On a label it can read as Flaxseed Oil, Flax Oil, Linseed Oil, Linseed — worth knowing when you scan an ingredient deck.
Flaxseed 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 Flaxseed 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.
