People have been putting rendered animal fat on skin for a very long time, and for most of that history nobody could say why it worked. The interesting part is that the reason turns out to be fairly simple, and it has to do with what your skin is already made of.
Here is the honest version of the science, including the parts that are still thin. If you would rather just try it, our Unscented Whipped Tallow is grass-fed tallow and organic coconut oil and nothing else, which makes it the cleanest way to see what a simple fat does on your own face.
Your skin barrier is mostly fat
The outermost layer of skin is called the stratum corneum. Dermatology references describe it as twenty to thirty layers of flattened cells, with a lipid mortar packed into the spaces between them. Those lipids are made and delivered by the cells below, which package ceramides and other fats into small structures called lamellar bodies and release them upward as the cells flatten and die.
That greasy mortar is doing most of the work people credit to skin generally. It is what slows water leaving from the inside and what makes the surface feel supple rather than tight. When it is depleted, by hot water, harsh surfactants, wind, low humidity or simple age, skin gets that papery, taut, reactive quality that no amount of water alone fixes.
Sitting on top of that is a second layer of oil from your sebaceous glands. Those glands supply roughly 90 percent of the lipids on the skin's surface, including free fatty acids and squalene.
So: fat underneath, fat on top. It follows that when skin feels dry in the stubborn way, the missing ingredient is usually not water.
Where tallow overlaps with skin's own lipids
Beef tallow is mostly three fatty acids, and the proportions are worth knowing because they are the whole basis of the argument for using it.
- Oleic acid, roughly 30 to 50 percent. A monounsaturated fat, and the same one that makes up a large share of human sebum. It is what gives tallow its softness and its slip.
- Palmitic acid, roughly 20 to 25 percent. A saturated fat that is also one of the free fatty acids found in the skin's own surface lipids.
- Stearic acid, roughly 15 to 25 percent. The one responsible for tallow being solid at room temperature, and for the structure a whipped balm holds.
Grass-fed tallow also carries small amounts of fat-soluble vitamins A, D, E and K that come along with the fat itself rather than being added to a formula. We would not want to oversell that. The quantities are modest, and nobody should buy a balm as a vitamin delivery system. But it is a real difference between grass fed tallow and a heavily processed industrial fat, and it is one of the reasons sourcing is worth caring about.
What that overlap actually buys you
This is the part where a lot of writing about tallow gets carried away, so let us be careful.
What a fat like this does on skin is well described. Dermatology references sort moisturizer ingredients into three groups. Humectants pull water toward the surface. Emollients smooth and soften by filling the gaps between skin cells. Occlusives form a physical barrier that slows water evaporating away. A water-free whipped tallow is an emollient and an occlusive, and a good one, because its fatty acids are close in character to the lipids already sitting in and on your skin.
That closeness is the honest claim. It is a fat your skin surface is chemically familiar with, applied where similar fats already live. That is why it tends to feel like skin rather than like a product, and why so many people who react to complicated formulas get along with a simple one.
The simplest version of the idea. Two ingredients, grass-fed tallow and organic coconut oil, whipped until it goes on light. No water, no preservative system, no fragrance. If the science above is interesting to you, this is the jar that tests it.
What the research does not say
Intellectual honesty matters more here than anywhere else on this site, because tallow is having a moment and a lot of confident nonsense is being written about it.
There are very few clinical trials on tallow as a finished cosmetic. Most of the evidence people cite is either research on the individual fatty acids, or general research on how emollients and occlusives behave on skin, and neither of those is the same as a trial of a jar of balm against a control. Anyone telling you that studies prove tallow does a specific thing to a specific condition is overreaching.
We have also seen claims attributed to journals that do not contain them, which is worse than no citation at all. Every source at the bottom of this page is one we opened and read before linking it.
So here is the line we hold. Whipped tallow is a cosmetic. It supports the look and feel of comfortable, well-moisturized skin. It is not a treatment for anything, and we will not describe it as one.
Why we blend it rather than use it neat
Pure tallow on its own is stiff and waxy and not much fun to apply. We whip ours with organic coconut oil, which softens the texture and makes it spread thinly enough to be practical on a face. Both fats earn their place. The result is a balm you can actually use daily rather than one that sits in a cupboard.
The scented jars are the same base with essential oils added. Only the Unscented jar is a two-ingredient product, and we say so plainly rather than letting the phrase cover the whole line.
If you want something lighter than a balm, our Pure Glow Face Serum takes the same idea in a different direction. It is eight organic plant oils, including argan, rosehip, jojoba and sea buckthorn. There is no tallow in it and no essential oils, and it layers thinner than a balm does.
Common questions
Is tallow really closer to human sebum than plant oils? In fatty acid profile, it is closer than many. That is a chemistry observation, not a promise about results, and plenty of plant oils are excellent on skin. We use both.
Does grass-fed actually matter? For the fat-soluble vitamin content and for how the animal was raised, yes. For the basic fatty acid backbone, less than the internet suggests. We source ours from grass fed cattle because we think it matters for both reasons.
Will it feel greasy? Whipped, and used in small amounts, it absorbs better than most people expect. A pea-sized amount covers a face. Using too much is the single most common mistake.
Is it safe on the face? It is a cosmetic and people use it on their faces daily. As with anything new, patch test first, and if you have a skin condition or you are treating something with a prescription, ask your own provider before adding anything.
We are Jeremie and Megan. We make every batch by hand in Loomis, California, from grass fed tallow, and our name is on every jar. If it arrives and it is not right for you, write to us and we will sort it out.
Batches are small. The unscented jar is our year round staple and we keep it stocked, and the seasonal scents come and go with the batch, so the collection page is the place to see what we have made lately.
