Date Seed Oil
Date seed oil is rated 3 on our list, in the moderate band, and that number is unconfirmed: we have not traced it to a published study (what unconfirmed means).
Like every rating here, it is for the raw ingredient tested alone, and a label does not print how much of it a product holds.
Is date seed oil comedogenic?
Date Seed Oil is rated 3 on the comedogenic scale, which is the moderate band.
An oil rich in phytosterols and ursolic acid, used for anti-aging and moisturizing.

- Unconfirmed. We could not trace this rating to a study we have read; the section on who rated it says what we checked.

What a 3 means in practice
Three is the middle of the scale. Fulton 1989 counted 2 to 3 as borderline in the rabbit-ear test: some plugging of the follicles, short of a clear positive. Whether it matters depends on how high it sits on the label and whether the product stays on your skin.
Two things change what this number is worth. Ingredients are listed in descending order of concentration, so date seed oil near the top of a label matters far more than date seed oil at the bottom. And the rating describes the raw ingredient on its own. A 2006 review in the Journal of the American Academy of Dermatology found that a rating for a single ingredient does not reliably predict how a finished formula behaves on human skin. The full story of the scale is here.
Who rated it
We could not trace the 3 on our list to a paper we have read. Neither paper we could read tests date seed oil. The list does not say where its numbers came from, so treat this number as unconfirmed rather than as one we can tie to a table.
Fungal acne
Date Seed Oil matches rule 4, plant or animal oil or butter , on the fungal acne checker. A plant or animal oil, mostly triglycerides. The rule comes from lab studies of what Malassezia yeast can feed on, and it is not a verdict on any product.

Each ingredient at 10 percent in propylene glycol unless stated, applied five days a week for two weeks, and graded 0 to 5 from the width of the follicles, measured by micrometer and under the microscope. The paper counts 0 to 1 as not significant, 2 to 3 as borderline and 4 to 5 as positive. Some grades depended on the supplier of the raw material, and some oils were also tested refined.
