The Latin word for the oil your face makes is sebum, and it means tallow.
Your sister has taken the dictionary at its word. She came home from a Saturday farmers' market with a small amber jar of whipped beef fat. Now it sits by her bathroom sink, beside the toothbrushes. She rubs a pea-sized scoop into her cheeks every January morning while the window frosts over, and she swears they have never felt softer.
She may be right about the softness. What nobody can tell her yet is whether the habit is good for her, because nobody has properly checked. Below is what is known, what could go wrong, and the gentler option that gets her the same winter comfort.
The short answer: No study has tested beef tallow as a face cream on real people. It can soften very dry skin the way any rich balm does, but it may clog pores, it spoils without preservatives, and homemade batches go unchecked for bacteria. Jojoba is the closer match to your skin's own oil.
Has anyone tested tallow on faces?
No. In 2024, a team of dermatology researchers in Alabama searched two large medical databases for every paper on tallow and skin. They screened 147 studies and kept 19. None was a controlled trial of tallow as a moisturizer on human volunteers.
What they found instead was a patchwork. There were lab studies of the fats tallow contains, animal studies, and older work on tallow in soap. The researchers flagged side effects as the area where those papers disagreed most.
A second team, at Michigan State University, went looking on YouTube, Instagram and TikTok in 2025. Posts promised help for acne, eczema and psoriasis, usually with no evidence attached. Most were made by influencers without health training, and most of them had something to sell.
So your sister's soft cheeks are real, and they count as experience. They are not proof, and no label can honestly promise more.
Why the jar feels so good in January
Tallow is solid at room temperature and melts at the warmth of a fingertip. Spread thin, it leaves a coating that slows down the water leaving the surface. Dermatologists call any ingredient that works this way an occlusive. Think of it as a lid on a simmering pot.
Canadian winter air is very good at pulling that water out. Indoor heating makes it worse. A lid of any kind, whether petroleum jelly, shea or tallow, will make a tight, flaky complexion feel calmer by morning. Tallow did not invent that trick. It is simply one more way to perform it.
The lid has a catch. The thicker the layer, the harder it is for your pores to empty. Dr. E. Victor Ross, who runs laser and cosmetic dermatology at Scripps Clinic in California, says plainly that tallow can clog pores for many users. Cleveland Clinic dermatologists warn that the same heavy texture can bring on breakouts.
The trouble with a farmers' market jar
Rendering suet at home means simmering it, straining it and pouring it into jars. Done carelessly, or stored too long, the result can spoil or grow bacteria. Dr. Ross points out that a batch can smell perfectly clean and still not be sterile. Many small makers never send a batch to a lab.
Pure tallow also carries no preservative, so it goes rancid sooner than a shop moisturizer. Rancid fat smells sharp and stale, and it is not something to massage in at 7 a.m.
The prettiest packaging often hides another problem. Makers love to add lavender or other scents, and fragrance is a common cause of itchy, red reactions. A beef allergy is not required, either. Cleveland Clinic notes that people can react to a tallow balm without being allergic to beef itself.
Ask the vendor three questions before you buy. Was the product notified to Health Canada? What else is in it? When was this batch made? A maker who answers all three without fuss is worth buying from.
| Your skin | Tallow on the face? |
|---|---|
| Very dry, never breaks out | A small amount may be tolerated; patch-test first |
| Acne-prone | Skip it |
| Rosacea or flaky, red patches around the nose | Skip it; it can aggravate both |
| Sensitive to scent | Only a fragrance-free balm |
Which oil is closest to your skin's own?
Jojoba. The surprise in this whole story is that the old Latin name misleads. Human sebum is a mixture, and about a quarter of it is a family of fats called wax esters. Italian dermatologists at the San Gallicano Institute in Rome point out that wax esters and squalene are found nowhere else in the body. They are the signature of your own sebum.
Tallow is mostly a different family, the fats that make up butter and lard. Your sebum contains those too, so the match is partial at best. The two signature ingredients are largely missing from the tub.
Jojoba, a shrub from the Sonoran Desert, fills its seeds with liquid wax esters instead of the usual kind. A 2013 review in an Italian dermatology journal calls it the main natural source of these waxes, and notes early evidence that it calms inflammation. Pressed from the seed, it pours like an oil but behaves more like the coating your pores already make.
Grandma's logic, with a lighter bottle
The old instinct to seal dryness in winter is sound. The order matters more than the product. The American Academy of Dermatology advises putting on moisturizer within a few minutes of washing, while the skin is still damp. The water you just added gets trapped underneath instead of escaping into the dry air.
The free part does most of the work. Wash with lukewarm water rather than hot, pat mostly dry, and seal it straight away. A bedroom humidifier helps when the furnace runs all night. None of it costs a thing, and all of it beats any single ingredient.
For the seal, press three or four drops of NOW Organic Jojoba Oil into damp cheeks. The maker describes it as cold-pressed, organic and remarkably similar in structure to skin's own natural oils. It also resists turning rancid, the very thing the market balm cannot promise.
If you love a rich, buttery balm, give it a job below the jawline. Divine Essence Shea Butter is certified organic and deodorized, so it carries no added fragrance. Warm a scoop between your palms and work it into heels, elbows and shins after a bath. The label warns against it for anyone allergic to nuts.
Run a fair trial before you crown a winner. Use one product at a time for two weeks, so a breakout has only one suspect. If your cheeks feel best after a fortnight of the desert oil, the switch costs you nothing but a story at the market.
Your sister's jar can stay by the sink. It just makes a better hand cream than a night cream.

Frequently asked questions
Can beef tallow cause an allergic reaction?
Yes. Cleveland Clinic dermatologists note that people can react to a tallow balm even if they are not allergic to beef, often because of added scents. Dab a little on your inner arm once a day for several days, and keep it off your face if any redness or itch appears.
How long does homemade tallow balm last?
No one has set a reliable shelf life, because pure tallow contains no preservative and every batch is rendered differently. Keep the lid closed, scoop with a clean spoon rather than fingers, and throw the jar out if it smells sour or sharp, or if the texture changes.
Can beef tallow protect my skin from the sun?
No. Tallow has no known sun-protective qualities, so it cannot stand in for sunscreen, even in winter or on the ski hill. If you like the balm, use it at night and wear a broad-spectrum sunscreen of SPF 30 or higher during the day.
Do tallow skincare products sold in Canada need approval?
They need notification, not approval. Under Canada's Cosmetic Regulations, every maker and importer must tell Health Canada about a cosmetic, including its ingredients, within 10 days of first selling it. Notification is not a safety test, so it says nothing about how well a balm works.
