Aloe Butter
Aloe butter is rated 5 on our list, in the high 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 aloe butter comedogenic?
Aloe Butter is rated 5 on the comedogenic scale, which is the high band.
Aloe extract blended with a heavy fat (like coconut oil) for deep moisturizing.

What a 5 means in practice
A 4 or 5 is the top of the scale. In the rabbit-ear test, Fulton 1989 counted 4 to 5 as a clear positive: the ingredient plugged the follicles, and did so repeatably. A person's skin reacts less readily than a rabbit's ear, and a product holds far less of the ingredient than the test did, so treat this band as the first thing to check in anything that stays on your skin. It does not prove the ingredient will cause a breakout. A rinse-off product is on the skin for seconds.
Two things change what this number is worth. Ingredients are listed in descending order of concentration, so aloe butter near the top of a label matters far more than aloe butter 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 5 on our list to a paper we have read. Neither paper we could read tests aloe butter. 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
Aloe Butter matches rule 4, plant or animal oil or butter , on the fungal acne checker. A butter, mostly triglycerides. The rule comes from lab studies of what Malassezia yeast can feed on, and it is not a verdict on any product.

- Aloe Butter is rated 5 on the comedogenic scale, which is the high band. We have not found a published study that grades it, so treat this number as unconfirmed.
- Is aloe butter non comedogenic?
- No. Aloe Butter is rated 5 on the comedogenic scale, which is the high band. That is the number on our list rather than a verdict on any product. We have not traced it to a published study, so treat it as unconfirmed.

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.
