I’m a Black guy living through harsh winters, and every year my skin gets ashy enough that I skip lotion and go straight to Vaseline.
This winter I tried beef tallow skincare from The VanMan Shop to see if it could keep my skin comfortable without feeling like I’m wearing grease all day.
I tried three of their products (a balm, soap, and an eye cream) and I’ll tell you what worked, what didn’t, and who this is worth it for.

- Best for: dry/ashy winter skin
- Skip if: acne-prone face
- Biggest difference: less ash + less reapplication
- Downside: price (especially the bison balm)
A review of experience using VanMan Shop’s beef tallow products
I went with The VanMan Shop because I spoke to the founder and liked their sourcing (Dakotas + Fatworks in Colorado). Most of their products also include a few simple add-ons like honey, beeswax, or essential oils.

Here is a quick review of the beef tallow products I started using in my routine from The VanMan Company.
VanMan Bison Tallow & Honey Balm
My first impression of VanMan Bison Tallow & Honey Balm was how tiny a 2 oz. tin is. I’m used to purchasing skin products in larger containers, so this was a surprise.
For comparison, a standard jar of Vaseline is 13 oz., and the Bison Tallow & Honey Balm is 2 oz.

The Bison Tallow Honey Balm is $111. That does include free shipping, which is a nice perk. A jar of vaseline is $7.
It’s $111 for 2 oz (free shipping), so yeah—this is premium-priced. It’s also their most expensive balm because bison costs more than beef.
The Bison Tallow Honey Balm is also infused with a lot of great natural additions, like:
- Raw Manuka Honey
- Organic Royal Jelly
- Organic Beeswax
- Organic Cold-Pressed Extra Virgin Olive Oil
- A blend of the essential oils
If you aren’t a fan of the essential oils, The VanMan Company also sells essential-oil-free version of the Bison Tallow Honey Balm.
Also, I just happened to pick up the most expensive beef tallow balm that VanMan offers. VanMan also sells:
There’s also an essential-oil-free version of the Tallow and Honey Face Balm.
The moment I touched it, I understood that 2 oz. was actually a great value.
You do not need a lot of tallow because it spreads easily, and a little bit goes a long way on your skin. Compared to Vaseline, a much smaller dollop covered a much larger surface area of my skin.
I barely used any on my lips as well, but hours later, I’m not showing any signs of gray, ashy skin—and I’m writing this in the midst of a January cold snap.

It doesn’t feel as light as lotion, but that’s to be expected. However, it doesn’t feel nearly as heavy as Vaseline and, in my experience, protects your skin just as well.
Obviously, the price is a little higher than your standard bottle of lotion or Vaseline, but it doesn’t come with any extra chemicals or irritants. It feels like it actually stays on the skin instead of disappearing in 10 minutes like most lotion.
One more thing about Bison Tallow and Honey Balm. It has a gentle, masculine smell. My wife immediately commented on it.
That’s the best way to describe it, and it’s a result of the essential oils added.

VanMan’s Tallow Soaps

The Vanman Shop also sells soaps made of tallow.
I added the soaps because regular bar soap dries me out in winter, bringing out the ashy skin.
While I can say I was definitely not as dry as I normally am after a few minutes out of the water, I wouldn’t use the soap without the using the balm afterwards. It’s not THAT good at retaining moisture.
With that said, it’s a hell of a lot better than just using bar soap.
I picked up the:
-
Pumpkin Spice Tallow Soap. It definitely smells like pumpkin spice, which is actually quite pleasant and got some nice compliments from my wife. This one is also listed on the site as “limited run,” so who knows how long it will last.
-
Pine Tar Tallow Soap. This one is my favorite soap. First, this one has a great smell. I’d define this as a masculine smell, almost like a musk, but “softened” by the pine tar.

Also, tea tree oil is a powerful antimicrobial agent and activated coconut charcoal enhances the soap’s ability to remove dirt without adding harsh cleansers or detergents. -
Honey and Tallow Soap. While vanilla definitely has a scent, and honey has a slight one, this is unscented. This is a great option if you aren’t a fan of fragrances, naturally added or otherwise.
VanMan also offers a tallow and coconut soap, which I’ll try next.
I’m pleased with the soaps; they smell great, and they are making my skin softer and less likely to be ashy.

VanMan’s Pearl Eye Cream
Eye cream is meant for the thinner, more sensitive skin around your eyes, so it’s usually gentler and more occlusive than a standard moisturizer.
The tallow, lanolin, beeswax, emu oil, and castor oil create a protective lipid layer that dramatically reduces water loss in the thin skin around the eyes. This is important because a lot of what people call ‘eye wrinkles’ are dehydration lines.. When you seal moisture in effectively, those lines soften fast. Not permanently, but noticeably.
The added ingredients—green tea, royal jelly, pearl powder, and essential oils—play a supporting role.. Green tea brings mild antioxidant support, royal jelly adds some skin-conditioning benefits, and pearl powder contributes more to cosmetic finish than anything transformative.
I’m only 40, but the best way to get rid of wrinkles is to not get them in the first place. So I’ll probably continue with this, if for no other reason than I actually notice a difference in the “freshness” of my eyes.
No one thinks I look my age now, and I’m confident that this product will keep it that way. With that said, this eye cream is on the pricier side.
It’s $56, but you use so little that a tin should last a while

What Is Beef Tallow?
To understand beef tallow, you first have to understand suet, and to understand suet, you have to understand visceral fat.
Beef tallow is rendered suet (the dense fat around a cow’s organs). Rendering removes water and proteins, which makes it shelf-stable and less likely to go rancid.
In ruminants (mammals with multichamber stomachs), we call this visceral fat “suet.” Tallow is produced by gently rendering suet to separate triglyceride fats from water and proteins, yielding a stable lipid matrix that is chemically the same as suet but has some unique properties.
First, tallow has a much longer shelf life than raw suet. This stability is due to the removal of elements that promote microbial growth and rancidity. Before suet is rendered into tallow, it contains:
- Water (Moisture) that enables microbial growth, hydrolytic rancidity, and enzymatic reactions.
- Proteins and peptides that serve as a food source for microbes
- Trace impurities like blood and connective tissue fragments that can easily break down
Removing these agents from suet makes it less reactive, less prone to oxidation, and more stable.
Why People Are Using Beef Tallow on Their Skin
So now that you understand what beef tallow is and where it comes from, we can explain why people use it on their skin.
Specifically, what benefits do you get from beef tallow that you don’t get from other lotions, creams, ointments, balms, or other topical solutions..
Skin barrier repair & occlusion
Healthy skin starts with an intact, healthy lipid layer.. The outermost layer of skin—the stratum corneum—is held together by a matrix of lipids that regulate water loss, block irritants, and modulate inflammation.
When that barrier is compromised, skin becomes dry, reactive, and more prone to irritation and hyperpigmentation.

What causes the skin’s lipid barrier to break down?
The skin’s lipid barrier doesn’t break down from one singular event. It’s usually the result of chronic, repeated, low-grade disruption that outpaces the skin’s ability to repair itself.
The most common driver is chronic exfoliation, especially when it’s done with chemicals.
Modern skincare relies on acidic compounds to accelerate skin cell turnover. These acids work by temporarily weakening the connections that hold the stratum corneum together.
The following acids are the main culprits.
- Over-exfoliation (acids/retinoids)
- Harsh cleansers + hot water
- Winter air (low humidity, wind)
- Inflammation (eczema/rosacea/acne)
- Aging (slower lipid repair)
These factors come together in a perfect storm that disrupts the skin.

Beef tallow supports the skin’s lipid layer in two ways

- Occulsion. Occlusion is just a scientifically precise way of saying something “closes or seals off.” Tallow forms a thin seal that slows water loss so your skin stays hydrated longer—especially after a shower.
- Biological mimicry. One of the reasons beef tallow behaves differently from many modern moisturizers is that it works through biological mimicry rather than chemical novelty. The fatty acids in tallow closely resemble those the skin already uses to build and maintain its own lipid barrier.
Many skincare products attempt to stimulate change by accelerating turnover or inducing controlled irritation. Tallow takes the opposite approach. Mimicking the skin’s native lipid architecture, beef tallow helps the barrier rebuild itself without triggering inflammation or stress responses.
In that sense, tallow doesn’t “treat” the skin so much as give it the materials it already knows how to use. This is why tallow often works best on compromised skin—over-exfoliated, irritated, or chronically dry—where repair matters more than stimulation.
Fatty acid profile of plant oils vs beef tallow

I touched on this in the last section, but a major reason beef tallow behaves differently on skin than most modern moisturizers is its fatty acid composition.
Most plant oils used in skincare—particularly seed oils—are rich in polyunsaturated fatty acids (PUFAs), especially linoleic acid. These fats contain multiple double bonds, which makes them chemically fragile.
When exposed to oxygen, light, or heat, they oxidize readily, forming lipid peroxides and other reactive breakdown products. On the skin, those byproducts can disrupt barrier lipids and contribute to irritation and inflammation, particularly in already compromised tissue.
Beef tallow has a very different profile. Compared to many plant oils, tallow is higher in saturated and monounsaturated fats, which are more stable and tend to sit on the skin longer without oxidizing as quickly.
Why beef tallow feels “heavier” than modern moisturizers
One of the first things people notice when they use beef tallow on their skin is that it feels heavier than most modern moisturizers. That sensation is often described as “greasy,” but it only feels that way if you’re used to modern, chemically-laden, artificially produced moisturizers.
Most of the modern moisturizers you buy are designed to feel light. They’re usually built around water, emulsifiers, fast-absorbing esters, volatile silicones, and texture modifiers designed to disappear quickly. I can’t count how many times I’ve seen “fast-absorbing” and “light feeling” used as marketing points.
That fast absorption feels elegant, but it also means the has a short functional lifespan on your skin. Much of what makes it feel good is designed to evaporate or absorb rapidly rather than persist and protect your skin.
Beef tallow feels more like petroleum oil, commercially known as Vaseline.
Both feel heavy. Both form an occlusive layer. Both are excellent at reducing transepidermal water loss. And both are often dismissed as “greasy” for exactly the same reason: they don’t disappear.
As a kid, Vaseline was the only thing I could use that didn’t leave me feeling dry, ashy, and forced to apply another layer in an hour. In fact, Vaseline is good at trapping water, making it known officially as an “emollient.” I didn’t use it in the summer. But it was my winter go-to, not only after a shower, but after I got in the swimming pool during middle and high school gym class.
Petrolatum is a highly effective inert occlusive. It forms a physical seal that traps moisture, but it does not interact with the skin beyond that. It doesn’t supply lipids the skin uses to rebuild itself, and it doesn’t integrate into the barrier structure. It simply sits on top and blocks evaporation.
Tallow also forms an occlusive layer, but it does so using biologically familiar fats rather than the byproducts of creating gasoline. Its matrix of saturated and monounsaturated fatty acids is the same class of lipids found in healthy skin. As a result, tallow not only seals moisture in; it also contributes structural lipids that can integrate into the skin’s existing lipid matrix.
Petroleum just protects skin, but beef tallow repairs it.
That’s also why tallow’s “heaviness” often fades more naturally than petrolatum’s. As the skin warms and absorbs what it can use, the remaining lipid layer softens and thins. Petrolatum, by contrast, remains largely unchanged until it’s washed off.
In that sense, tallow occupies a middle ground. It offers the same level of protection people seek in petrolatum, with the added advantage of biological compatibility.
Who Should and Shouldn’t Use Beef Tallow
Tallow isn’t for everyone. Used correctly, it can be extremely effective. Used indiscriminately, it can cause problems.
You should DEFINITELY use beef tallow on your skin if you have:
- Dry skin. If your skin consistently feels tight, flaky, or uncomfortable—especially after washing—tallow’s occlusive and lipid-restorative properties can be a major benefit. Think a lighter version of Vaseline that works almost as well, but the trade-off is that it actually is setting your skin up for long-term hydration.
- Compromised skin barrier. If you’ve relied heavily on exfoliation, harsh cleansers, or retinoids—or your skin is beat up from environmental stress—start using beef tallow. Beef tallow will protect and repair your skin without over-stimulating it and making it worse in the long run.
- Gotten older. As of this writing, I’m going to be turning 41 this year. I always say that 40 is the age when either everyone looks like they’re in high school, or you think they’re much older than you. A big reason for this is that aging affects your face because Father Time’s assault is relentless— but you can definitely do something about it by repairing your aging lipid barrier and getting some bounce back in your skin.
As we age, lipid production declines and recovery slows. Tallow helps compensate for that loss by reinforcing the barrier and reducing water loss, which can make you look more youthful.
You should AVOID using beef tallow on your skin if you have
- Active acne. If you’re actively breaking out, especially with inflammatory or cystic acne, tallow may be too occlusive—at least on the face. Spot testing or limiting use to non-facial areas is the safer approach.
- Malassezia-prone skin. Skin prone to fungal acne or Malassezia overgrowth may react poorly to certain fatty acids. Occlusive lipids can worsen symptoms in susceptible individuals.
- Hot, humid environments. In heat and humidity, heavy occlusives can trap sweat and heat against the skin, increasing irritation. This is the same reason why I never used Vaseline in the summer. Tallow will still do its job, but it might feel too heavy in the summer months.
How to choose a high quality beef tallow product for your skin
All beef tallow comes from beef suet, but not all beef tallow is the same.
There are two things that you have to know about the tallow products you use:
Where the tallow is sourced from and how it was rendered.
All Beef Tallow Comes From Cows, But Not All Cows Are Equal
Beef tallow is only as good as the suet it’s rendered from, and the quality of that suet is shaped long before rendering ever begins. The cow’s environment, diet, and finishing practices all influence the chemical composition and stability of the end product.
High-quality tallow comes from cows that are
- Pasture Raised
- 100% Grass-Fed
- Grass-Finished
In much the same way that any high-quality beef product falls under these categories, tallow is no different.
Each of these conditions affects fat differently, and importantly.

Why Pasture Raised Matters
Pasture-raised cattle spend their lives outdoors, moving, grazing, and experiencing normal metabolic cycles. This matters because chronic stress and confinement alter fat metabolism.
Stressors common in confined and intensive feeding systems—such as handling, transport, crowding, and environmental extremes—elicit systemic inflammatory responses in cattle, marked by increased pro-inflammatory cytokines (e.g., TNF-α and IL-6) and altered hormone signaling.
These physiological changes trigger changes in metabolism that affect how nutrients are distributed to the cow’s adipose tissue, including the suet. Research has shown that stressed animals exhibit a different hormonal and immune system profile than that of animals in more natural, low-stress environments (Cheng et al., 2022).
Cattle raised on pasture, with natural forage diets and lower stress from being able to roam free, show differences in fat composition and metabolism compared with animals finished on grain (Duckett et al., Journal of Animal Science; Alfaia et al., Meat Science). From a practical standpoint, they also have cleaner fat depots, less contamination from environmental residues, and more consistent tissue quality.
For making high-quality beef tallow, this means a cleaner starting material that renders more predictably and produces a more stable end product.
Why 100% Grass-Fed Matters
Grass-fed cattle consume diets that are lower in omega-6–rich fats, higher in fiber, and free from concentrated starch. This enables a more complete biohydrogenation, converting unstable polyunsaturated fats (PUFA) into saturated fats such as stearic and palmitic acids and monounsaturated fats such as oleic acid (Jenkins et al., 2008).
Grain-heavy diets increase the proportion of residual PUFAs that escape full biohydrogenation and end up stored in body fat. When that occurs, it makes the fat more prone to oxidation once rendered and exposed to air.
If you’re going to use tallow on your skin, lower PUFA content means greater oxidative stability and a reduced likelihood of irritation over time.
Why Grass-Finished Matters Most
Did you know that “grass-fed” doesn’t mean that it was fed grass its entire life?
It’s supposed to carry that meaning, and the United States Department of Agriculture (USDA) is actually pretty clear-cut on the definition of grass-fed:
“Animals are fed only grass and forage, with the exception of milk consumed prior to weaning.”
The problem is that the term grass-fed has serious marketing value, and enforcement
In practice, it isn’t.
As detailed in a 2015 investigation by Civil Eats, most cattle in the United States spend a significant portion of their lives eating grass before being moved to feedlots and grain-finished for the final months prior to slaughter.
Many cattle are grass-fed early in life and grain-finished later to accelerate weight gain. That final feeding phase disproportionately affects fat composition because visceral fat is metabolically responsive, late dietary changes are rapidly reflected in stored fat, and grain finishing sharply increases PUFA when it has the most effect: right before the animal is used for sustenance and products..
Unlike USDA organic certification, which requires extensive audits and third-party verification, “grass-fed” is regulated as a marketing claim rather than a production standard.
Producers are allowed to just self-certify that the cows were grass-fed. Combine that with oversight split among different USDA agencies that don’t consistently communicate and coordinate, and the result is limited enforcement, incomplete record-keeping, and consumers having to hope that the rules were followed.
While the grass-finished label on cattle is still treated as a marketing claim, it’s one that’s far rarer because grass-finished beef is significantly more expensive to produce relative to just grass-fed. People don’t mind paying, but with that comes a new level of scrutiny, so most farmers avoid it.
Suet made from grass-finished beef produces tallow with a more stable fatty-acid profile, lower susceptibility to oxidation, and greater consistency between batches.
This translates into tallow with a longer shelf life, a more predictable texture, and a better product for your skin.
Now that we’ve covered the supply side of tallow and what to look out for, we have to examine the differences between the two primary production models: wet and dry
Dry Tallow vs Wet Tallow: You Need To Know The Difference
The difference between wet-rendered and dry-rendered tallow has real consequences for stability, shelf life, and skin tolerance.
And, unlike trusting that your cow was actually let out to pasture to graze on grass for its entire life, the difference between “dry” and “wet” tallow is much easier to discern.

What “Dry-Rendered” Tallow Means
The process of dry rendering involves slowly heating suet without added water. As the temperature rises, the fat melts out of the tissue, while residual moisture evaporates and proteins denature.
The end result is a tallow that is virtually water-free, free of soluble proteins and enzymes, highly resistant to microbial growth, and structurally intact at the fatty-acid level.
Because bacteria, fungi, and enzymatic reactions all require water, dry-rendered tallow is biologically inert. This makes it exceptionally stable for topical use.
What “Wet-Rendered” Tallow Means
Wet rendering uses added water or steam to extract fat. While this can increase yield and speed up processing, it introduces tradeoffs.
Wet-rendered tallow often retains trace moisture and can carry water-soluble proteins or impurities. As a result, it typically requires more aggressive filtration or the use of preservatives and has a shorter shelf life once exposed to air
Even small amounts of residual water can support microbial growth, increase hydrolytic rancidity, and reduce long-term stability on the skin.
For food applications, this difference may be negligible. For skincare, it matters.
Why This Difference In Rendering Tallow Matters for Skin
No one’s skin is perfectly clean and sterile, but unstable lipid products can worsen irritation rather than relieve it. For example, the damaging effects of linoleic acid—a polyunsaturated fatty acid that’s unstable—on the skin’s protective lipid barrier (Angelova-Fischer et al., 2025).
Dry-rendered tallow does not introduce water that could disrupt the skin barrier. It is less likely to oxidize or break down on the skin surface, reducing the risk of irritation caused by degraded proteins or enzymes.
Wet-rendered tallow is more prone to developing off-odors over time, to break down during storage, and to trigger irritation in sensitive or inflamed skin.
For anyone using tallow as a barrier-supportive moisturizer, these differences are not just theoretical. They directly affect performance and tolerance.
Final Verdict: Is Beef Tallow Worth Using on Skin?
It’s not magic, but it’s also not a gimmick.
Once you understand what it actually is and how it works, you realize why it behaves differently than most “modern” skincare.
It’s stable, free of contaminants, and helps the skin repair itself. It also makes your skin look fresher and younger by keeping moisture in rather than letting it escape.
And because its fat profile is dominated by saturated and monounsaturated fatty acids, it holds up better on skin than PUFA-heavy oils that oxidize easily and can irritate compromised tissue over time.
It’s also slightly but noticeably pricer than what you’re probably used to paying, but you didn’t find this article because you were trying to nickel-and-dime your way to better skincare. Besides, it kind of balances out anyway.
And the pine tar tallow soap probably does a better job at cleaning your skin than traditional bar soap. That’s just my speculation.
The VanMan Shop has a great line up of products. I recommend you check them out and, if you buy something, I’ll keep a small commission at no extra cost to you.
You can think of it as saying “thank you” for this article.
