Beef Tallow for Skin: Why Is It Trending on TikTok and Is It Actually Worth Trying?
Your TikTok feed is full of it. Influencers are slathering it on at night and waking up glowing — or so they claim.
Beef tallow for skin has become one of the loudest beauty trends of the year, marketed as a natural, “chemical-free” cure-all for everything from acne to eczema. But dermatologists are pushing back, warning that the science behind the hype is thin and the risks — clogged pores, irritation, breakouts — may outweigh any glow.
Here is what the research actually says, what experts are warning about and how to think about beef tallow before you smear rendered cow fat on your face.
What is beef tallow, exactly?
Tallow is a solid fat derived from animals. Beef tallow is rendered fat from cows, usually from the suet that surrounds the kidneys and other organs, according to UT MD Anderson. It is made by slowly melting beef fat, then straining and cooling it into a solid that is firm at room temperature but melts on contact with skin, similar to coconut oil.
It is rich in fatty acids — including oleic, palmitic and stearic acids — and has long been used for cooking, soap and candle making. In skincare, it is valued for being occlusive, meaning it helps lock in moisture, and for being chemically similar to the skin’s natural oils.
“It gets promoted a lot on social media because it’s natural,” dermatology resident Angela Wei, MD, told the Cleveland Clinic. “People seem to like it because it’s something that’s been around for a long time and marketed as ‘chemical-free.’”
Why is beef tallow for skin trending now?
The current surge is being driven almost entirely by influencers, celebrities and brands online — not by clinical research. A 2025 study analyzed top posts about beef tallow for skin on YouTube, Instagram and TikTok and found that 82% of posts across all platforms recommended tallow for skincare.
The same study found that risks were rarely mentioned, scientific evidence was minimal and very few posts recommended consulting a healthcare professional first. Financial bias was prevalent on every platform.
Most posts came from influencers and bloggers without medical expertise and claims centered on using beef tallow for acne, eczema, psoriasis and as a general moisturizer.
Despite that, dermatologists and other medical professionals were the least likely group to promote it.
What are the potential benefits of beef tallow for skin?
There is some plausible biology behind the trend. The benefits of beef tallow for skin most often cited by supporters come down to its fatty acid profile, which closely mirrors human sebum.
A 2024 scoping review noted that the fatty acids in tallow can act as both emollients, which smooth and soften skin, and occlusives, which form a protective seal. Tallow also contains small amounts of fat-soluble vitamins A, D, E, K and B-12, which play roles in cell turnover, inflammation and wound healing.
“Its fatty acids closely resemble the natural oils of the skin, allowing it to effectively replenish moisture,” Michele Green, MD, a board-certified cosmetic dermatologist in New York City, told GQ in May 2026. “Linoleic acid, a type of fatty acid in beef tallow, also has known anti-inflammatory properties that can reduce redness and swelling.”
What are the risks and side effects?
This is where dermatologists get cautious. Tallow is highly comedogenic, meaning it can clog pores and trigger breakouts — particularly for people with oily or acne-prone skin. It can worsen sensitivity or rosacea, especially when fragrance is added, and may cause redness, itching or rashes in people with allergies.
Dr. Wei adds that it offers no sun protection and can, in fact, increase sensitivity to sunburn. And because there is no standard formulation, quality varies widely from product to product.
“Beef tallow doesn’t have a standard formulation, and it’s not developed in a controlled way,” Dr. Wei told the Cleveland Clinic. “As a result, it is hard to know what each product truly contains, and how many nutrients are actually going into the skin to create the effects they claim.”
Board-certified dermatologist Corey L. Hartman, MD, was blunter. “If you have oily skin, which men tend to have, using comedogenic products is asking for a breakout,” he told GQ in May 2026. “When products get stuck in pores and mix with oil, acne is almost guaranteed.”
Most dermatologists still recommend sticking with moisturizers backed by clinical research.
“There’s no evidence that shows beef tallow has any additional benefits for your skin beyond being a natural moisturizer,” Wei said. “There are other moisturizers out there with more consistent formulations that are better and safer for use on the skin.”
