The Ingredient That Was Always There: A History of Tallow in Skincare

Tallow is having a moment right now, and the conversation around it tends to be framed as a discovery. A rediscovery, more accurately. Because tallow was never obscure. For most of human history, it was simply how people cared for their skin. The story of how it disappeared from our medicine cabinets and bathroom shelves, and why it is returning, tells you a great deal about the skincare industry and even more about what skin actually needs.

Before there were products, there was fat

Rendered animal fat has been used as a skin treatment for thousands of years across nearly every culture on earth. Ancient Egyptians used it as a base for medicinal preparations. Roman physicians included it in formulas for wounds and dry skin. Indigenous peoples across North America used bison fat specifically for skin protection, hair conditioning, and wound care long before European contact. Medieval Europeans used lard and tallow in preparations that functioned as everything from hand cream to lip balm to salve for chapped and cracked skin.

These were practical people solving practical problems. They observed that animal fat, particularly from grass-fed animals, kept skin soft, protected it from the elements, and helped wounds heal. They did not have the vocabulary of fatty acids or biocompatibility, but they had generations of observed results. And those results were consistent enough that the practice persisted for centuries without significant challenge.

What changed in the twentieth century

The shift away from tallow happened in stages, and it was driven more by commerce than by science. The early twentieth century saw the rise of the modern cosmetics industry, and with it, an enormous commercial incentive to replace simple, inexpensive, and widely available ingredients with proprietary formulations that could be patented, marketed, and sold at significant markup.

Petroleum derivatives entered the picture first. Vaseline was introduced in the 1870s and positioned as a modern, clean alternative to animal fats. By the mid-twentieth century, synthetic emollients, silicones, and laboratory-derived compounds had become the industry standard. These ingredients were cheap to produce at scale, stable over long shelf lives, and easy to work into the rich, smooth textures that consumers associated with luxury.

Animal fats, by contrast, were perishable, variable in quality depending on source, and associated in the consumer imagination with something rustic and unrefined. The message, reinforced decade after decade through advertising, was that science had improved on nature. That the new was better than the old. That complexity and innovation were more trustworthy than simplicity and tradition.

For many people with sensitive or reactive skin, the consequences of that shift have been decades of irritation, barrier disruption, and a cycle of trying product after product looking for something that actually works.

The ingredient was always there. It worked for centuries before the industry decided it needed replacing. The discovery happening now is really just a remembering.

What was lost in the transition

The fatty acid profile of tallow is something no synthetic compound has fully replicated. Oleic acid, palmitic acid, and stearic acid make up the majority of both tallow and human sebum. This is what makes tallow biocompatible in the truest sense of the word. Your skin has evolved over millennia to work with these specific lipids. It recognizes them, absorbs them readily, and uses them to build and maintain the barrier that keeps everything in balance.

Synthetic emollients work on the surface. They create the sensation of moisture and the appearance of smooth skin, but they do this by sitting on top of the skin rather than integrating with it. For skin that is already compromised, this distinction is everything. A synthetic film does not repair a damaged barrier. It masks it.

The fat-soluble vitamins that come naturally with tallow from well-raised animals, including vitamins A, D, E, and K, were also lost in the move to synthetic formulations. These vitamins play genuine roles in skin health, from supporting cell turnover to providing antioxidant protection to supporting collagen synthesis. Getting them through a natural ingredient is meaningfully different from getting them as isolates added to a formula after the fact.

Why the return is happening now

The resurgence of tallow skincare is part of a broader cultural reckoning with what we put in and on our bodies. People are reading ingredient labels. They are asking where things come from and how they were made. They are connecting the dots between the simplicity of ancestral approaches and the chronic skin issues that have become so common in an era of synthetic-heavy formulations.

There is also a growing body of consumer experience, shared across communities and platforms, of people who switched to tallow-based routines after years of struggling with sensitive, reactive, or chronically dry skin and found relief they had stopped expecting. This kind of experiential evidence carries weight precisely because it is so consistent and so specific.

Why bison, and why it matters

At Luna and Laurel, we chose bison tallow specifically because bison are almost exclusively grass-fed and pasture-raised animals. Their fat reflects the quality of the land they graze on and the natural diet they live on. That translates into a tallow with a richer CLA content, a higher omega-3 profile, and a lighter texture than conventional beef tallow.

The ancestors who relied on animal fat for skin care were working with animals raised on their natural diet in their natural environment. We are doing the same thing, with the additional benefit of understanding exactly why it works. The history is long. The science is clear. And the results speak for themselves.
