Beef Tallow Skincare: Dermatologists Weigh in on the Viral Beauty Trend

A centuries-old skincare practice has made an unexpected comeback in the beauty community: beef tallow. This traditional ingredient, once a staple in historical skincare routines, has gained significant traction on social media platforms as an alternative to conventional moisturizers.

Beef tallow, derived from the fat surrounding cow kidneys, is processed into a butter-like consistency for use as a moisturizer. Despite its unconventional nature, the trend has gained such momentum that companies like Hearth and Homestead in Virginia have seen their tallow-based products sell out during major shopping events.

The Science Behind Tallow Skincare

Lily Wilmoth, founder and president of Hearth and Homestead, explains that their tallow products use exclusively grass-fed beef suet. The production process involves harvesting, grinding, and rendering the fat before combining it with herb-infused olive oil. The mixture is then whipped, cooled, and jarred for consumer use.

“It’s not the back fat or other types of fat that you might find on your steak,” Wilmoth emphasizes. “It’s a very specific fat that our ancestors recognized as special, containing higher concentrations of nutrients compared to other animal fats.”

Professional Perspectives

Dr. Brendan Camp, a New York-based dermatologist, confirms that beef tallow generally works well with most skin types. He explains that it functions as an emollient, filling in skin texture irregularities while trapping moisture. The presence of omega-3 fatty acids and various vitamins helps maintain skin barrier health and provides protection against oxidative stress.

However, not all dermatologists share the same enthusiasm. Dr. Tiina Meder, a London-based cosmetic safety expert, presents a different perspective. Drawing from her experience in Estonia during the 1970s, she recalls beef tallow being used out of necessity rather than choice. “Beef tallow lipids have very little in common with lipids of the human skin,” she explains, noting the absence of crucial components like linoleic acid, which plays a vital role in skin health.

Considerations Before Use

While tallow-based skincare products have gained popularity, they may not suit everyone. People with oily skin might find them too heavy, and those with sensitive skin should perform patch tests before full application. Furthermore, it’s important to note that these products, like many over-the-counter supplements, aren’t regulated by the FDA.

For those seeking alternatives, Dr. Camp recommends considering basic moisturizers free from fragrances and dyes, containing proven hydrating ingredients such as ceramides, glycerin, hyaluronic acid, and squalane.
