Short answer: Beef tallow has no published comedogenic rating, so nobody can honestly call it non-comedogenic. Its main fatty acids graded in the borderline range (2 to 3 out of 5) when tested individually, and the closest graded fats, such as cocoa butter, scored high. For acne-prone skin, tallow is a higher-risk choice than low-graded oils like sunflower or squalane.
Key takeaways
- Tallow was never graded in the 1989 Fulton survey that most comedogenic lists rely on.
- It is roughly 37 to 43% oleic acid, 24 to 32% palmitic, 20 to 25% stearic and 3 to 6% myristic acid, with only 2 to 3% linoleic acid.
- We found no published controlled study testing tallow on acne-prone human skin.
- The "it matches your skin's own oils" claim skips the fact that acne-prone skin benefits most from linoleic acid, which tallow barely contains.
Why There Is No Tallow Rating?
Most comedogenic ratings online trace back to James Fulton's 1989 rabbit-ear survey in the Journal of the Society of Cosmetic Chemists. It graded well over 100 ingredients, including 23 oils and fats, but tallow is not among them (Fulton, 1989).
So any tallow brand quoting a rating of 0, 1 or 2 is borrowing a number with no source. That does not prove tallow clogs pores. It means the evidence has to be built from its parts.
What Tallow Is Made Of?
Beef tallow is rendered beef fat, made almost entirely of triglycerides. The Merck Index lists its typical composition as follows (Merck Index via DrugFuture):
| Fatty acid | Share of tallow | Fulton 1989 grade as a free fatty acid (0 to 5) |
| Oleic acid | 37 to 43% | Not graded as a free acid in Table I; reported strongly comedogenic in other rabbit-ear work |
| Palmitic acid | 24 to 32% | 2 |
| Stearic acid | 20 to 25% | 2 to 3 |
| Myristic acid | 3 to 6% | 3 |
| Linoleic acid | 2 to 3% | Linked to fewer microcomedones in human study |
Fulton found that mid-length fatty acids such as lauric and myristic acid were the strongest follicle irritants, and that longer chains caused less reaction. A separate rabbit-ear study found oleic acid and its peroxides produced fairly large comedones (British Journal of Dermatology, 1983).
One caveat cuts the other way. These grades are for free fatty acids, while tallow holds them bound as triglycerides, which can behave differently on skin. That is exactly why a direct test of tallow is missing evidence, not a formality.
The closest comparisons we do have
Solid, saturated-rich fats are the nearest graded relatives of tallow. In Fulton's table, cocoa butter graded 4 and hydrogenated vegetable oil graded 3, and Fulton noted that cocoa butter had long been known clinically to cause pomade acne.
Compare that with the oils that graded 0, sunflower and safflower, which are dominated by linoleic acid. A double-blind study found topical linoleic acid shrank microcomedones by almost 25% in one month (Letawe et al., 1998). Tallow sits at the opposite end of that spectrum.
Using a tallow balm already? Many add essential oils, honey or other butters. Scan the jar to see every ingredient's rating, not just the tallow.
Does Tallow "Match" Your Skin?
This is the main marketing claim, and it is only partly true. Tallow and human sebum both contain triglycerides and saturated fats. But sebum also contains wax esters and squalene that tallow largely lacks, and research on acne-prone skin points to too little linoleic acid as part of the problem, not too little of what tallow supplies.
Resemblance also does not equal safety. Your own sebum is a key ingredient in clogged pores in the first place.
Who Might Do Fine With Tallow?
People with dry, non-acne-prone skin may find a tallow balm comfortable, much as they would with cocoa or shea butter. Rinse-off use, such as soap made from sodium tallowate, carries far less contact time than a leave-on balm.
If you get closed comedones (small skin-colored bumps) easily, a leave-on tallow product on your face is the riskier bet.
How To Test Tallow Safely If You Want To Try It
- Scan the product first and note any other high-graded ingredients, such as coconut oil or cocoa butter.
- Patch-test along the jaw for two to four weeks, since comedones can take weeks to appear.
- Introduce nothing else new during the test, so you can trust the result.
- Stop if small bumps appear in the test area, and give the skin 4 to 6 weeks to settle.
FAQs
Is tallow better than coconut oil for acne?
Neither has strong human data. Coconut butter graded 4 in Fulton's survey, and tallow is ungraded with borderline-graded components, so neither is a low-risk pick.
Is grass-fed tallow less comedogenic?
We found no study comparing grass-fed and grain-fed tallow on skin. Diet changes fatty acid ratios somewhat, but not into the linoleic-rich range of sunflower oil.
What does tallow look like on an ingredient list?
Look for "tallow", "beef tallow" or, in soap, "sodium tallowate".
