Before petroleum-derived ingredients. Before silicones. Before the modern cosmetics industry existed at all.

People used fat on their skin.

This is not a primitive or desperate measure. Animal fats, plant oils, and beeswax were the backbone of skin care across virtually every culture in human history. The ancient Egyptians used them. Greek and Roman physicians described their preparation and use. Medieval herbalists recommended them. They worked well enough that people did the same thing for thousands of years, in different climates, in different cultures, with remarkably similar results.

Today, a product like Nettie's Bee Deer To Your Skin Moisturizing Cream, made with deer tallow, honey, and other simple ingredients, reads as revolutionary. A return to basics. Something you have to search for.

But this cream is not new. It's old. What's new is that we forgot.

Why fat is good for skin

Quick answer: Fat, in the form of animal tallow, plant oils, or beeswax, is one of the best moisturizers for skin because it matches skin's own composition. It seals in moisture, supports skin barrier health, and doesn't require petroleum derivatives or synthetic compounds.

Human skin produces its own oil, called sebum. Sebum is made of fats and waxy compounds that protect and moisturize skin. When skin is healthy, it makes enough sebum to stay soft and supple.

But skin gets dry. From sun exposure, cold weather, harsh cleansers, age, genetics, or just the environment. When skin is dry, adding fat back helps it.

The reason fat works is simple: fat is what skin needs. When you apply a fat-based moisturizer to skin, the fat integrates into the skin's own lipid structure. It fills in gaps, seals the moisture barrier, and works with the skin rather than on top of it.

Synthetically-derived moisturizers (silicones, mineral oils from petroleum) sit on top of the skin. They feel smooth and they seal moisture in, but they don't integrate the way natural fats do. They're occlusive. They work, but they're not the same.

Why we switched away from fat

Petroleum was cheap. After World War II, the oil industry had excess capacity. Petroleum derivatives became the building blocks of everything from plastics to cosmetics. Mineral oil (a petroleum byproduct) became the base of most commercial moisturizers because it was cheap and stable and didn't go rancid like animal fats could.

At the same time, the cosmetics industry was professionalizing. Products needed to be standardized, shelf-stable, and manufacturable at scale. Animal fat varies depending on the animal's diet. Plant oils vary by harvest. They can go rancid. Petroleum derivatives don't have those problems. They're consistent. They're predictable.

The industry's convenience became the customer's normal. By the 1980s, almost no one was using traditional fat-based creams anymore. The knowledge was displaced so completely that using tallow on your face reads as a trend now, not as something people have been doing since before written history.

The return of tallow (and why it never left)

Tallow is beef fat rendered down. It's been used on skin for as long as humans have kept cattle. Herbalists and traditional healers never stopped using it. Indigenous peoples across North America never stopped using rendered animal fats on skin. But it disappeared from the mainstream so thoroughly that when people started making tallow-based skincare products 10-15 years ago, it felt radical and new.

Tallow works because it's almost identical in composition to human skin oil. Tallow is high in palmitoleic acid, which is a component of human sebum. When you apply tallow to skin, the skin's lipid barrier recognizes it as"food" and integrates it efficiently.

The same is true of other traditional fats: lard (pig fat), goat tallow, plant oils like jojoba and squalane, and beeswax. All of them are made of compounds that skin knows how to use.

How to use fat-based skin care

A cream made with tallow, honey, and perhaps some plant oils or essential oils is best used after cleansing, while skin is still slightly damp. The moisture on the skin helps the cream spread and integrate.

Use a small amount. Fat-based creams are concentrated. You need less than you would with a lighter, more commercial moisturizer. A dime-sized amount for the whole face is often enough.

At first, skin might feel oily. That's because it's not used to real sebum. Keep going. Within a week or two, skin often adjusts and the cream feels less greasy and more integrated. This is skin re-learning how to work with natural fat.

If you have very oily skin naturally, a heavy tallow cream might not be for you. But even oily skin often has dry patches, and a tallow-based cream can work well as a spot treatment on those areas.

Quality matters

Not all tallow is the same. Tallow from grass-fed, pasture-raised cattle is different from tallow from conventional feedlot cattle. The animal's diet affects the fat's composition and the cream's absorption profile.

The same is true of honey and plant oils. Quality matters. Nettie's Bee Deer To Your Skin is made with tallow from known sources and raw honey. That's not marketing language. It's the difference between a product that works and one that doesn't.

Why this matters

Using a tallow-based cream means you're choosing a product that's been proven safe and effective for thousands of years. You're using something simple: rendered fat, honey, maybe some plant oil or essential oil. Nothing that requires a chemistry degree to pronounce.

More important, you're opting out of the assumption that newer and more scientific means better. Sometimes the old thing is the best thing. Tallow is one of those things.
