Beef Tallow for Skin and Cooking: Claims Checked
Beef tallow is a rendered animal fat now promoted for skin care and cooking; dermatology reviews find little human evidence, and heart guidance on saturated fat applies to eating it.

Short answer: two dermatology reviews found little human research on tallow for skin, and a 2025 analysis of social media found that claims about acne, eczema and psoriasis mostly lacked cited evidence. [1][2] For eating, heart-health sources advise limiting saturated fat, though the sources we read give no figure for tallow itself. [3][4]
The claims as marketed
Tallow is a solid fat from animals, here beef. [1] Online posts claim benefits for acne, eczema (atopic dermatitis) and psoriasis, and its popularity has been linked to demand for natural and sustainable beauty products. [1] The sections below check these claims against what reviews found. No brands or products are listed or ranked here.Tallow for skin: what research shows
| Claim | What the source found | Strength of evidence | What was studied |
|---|---|---|---|
| Tallow treats acne, eczema or psoriasis | A cross-sectional analysis of YouTube, Instagram and TikTok posts found these claims were common but largely lacked cited evidence, most promoting posts showed financial bias and were by people without healthcare credentials, and existing evidence mostly concerns tallow's ingredients. [1] | Marketing claim; insufficient evidence | Social media posts, not patients |
| Tallow is good for human skin | A scoping review screened 147 studies and kept 19 (comparative, basic science and animal studies). It found significant research gaps on use on human skin. [2] | Insufficient evidence | Mixed lab, animal and comparison studies |
| Tallow is free of side effects | The same review said sources disagreed most on side effects of topical tallow and that more controlled research is needed. [2] | Insufficient evidence | Mixed |
Proper evidence not found in the sources we read (we searched PubMed for tallow skin care, dermatology and eczema studies) for randomized trials of tallow on acne, eczema or psoriasis in people.
Traditional use: the scoping review notes tallow has long served as a cooking fat and as an ingredient in soaps. [2] Reports of historical skin use were not described in the sources we read.
Tallow for cooking
Tallow has long been used as a neutral cooking fat. [2] A 2025 laboratory study in China found that tallow broke down less during repeated deep frying than the plant oils it was tested against. This measures how the fat behaves in a fryer, not what it does to health. [5]For health, the question is saturated fat:
- MedlinePlus lists butter, palm and coconut oils, cheese and red meat as high in saturated fat, and says the Dietary Guidelines for Americans recommend keeping saturated fat under 10% of daily calories. [3]
- The American Heart Association (2017) concluded that lowering saturated fat and replacing it with unsaturated fats, especially polyunsaturated fats, will lower cardiovascular disease. [4]
- A Cochrane review (2020) found that cutting saturated fat reduced combined cardiovascular events by 17%, with little or no effect on all-cause death. [6]
- A 2026 analysis of randomized trials opens by noting that debate about saturated fat advice continues. [7]
None of the sources we read gave a saturated fat figure for tallow itself. A food-chemistry study found that the liquid part separated from tallow had lower saturated fatty acids and cholesterol than whole tallow. [5] Ask a clinician or dietitian how fats fit your cholesterol and heart risk. See coconut oil vs olive oil for a related fats comparison.
Frequently asked questions
Does beef tallow treat eczema or acne?
No source we read shows that. Reviews found little human research and promotional claims that mostly lacked evidence. [1][2]
Is tallow better for skin than other moisturizers?
Proper evidence not found in the sources we read. The scoping review found research gaps for human skin. [2] See skin barrier care.
Is cooking with tallow healthy?
Tallow is a solid animal fat. Heart-health guidance advises limiting saturated fat and replacing some with unsaturated fats. [3][4]
Why do so many posts promote tallow?
A social media analysis found most promoting posts showed financial bias. [1]
Should I patch test tallow products?
Reports of side effects differed between sources, so a cautious approach makes sense. See the patch testing page and ask a dermatologist. [2]

Safety and who should ask first
- Skin: reactions to tallow were inconsistent across sources. [2] Any skin product can cause irritation or allergy. See patch testing natural ingredients and natural skincare claims checked. Do not put homemade or unlabeled products on broken skin, eczema flares or a baby's skin without asking a clinician.
- Existing skin disease: eczema, psoriasis and acne have proven treatments. Ask a dermatologist rather than replacing them with an unproven product. See natural ingredient vs medical treatment.
- Medicines, pregnancy, breastfeeding, children, liver and kidney disease: not described for tallow in the sources we read, so we make no claim. See medication interactions.
- Homemade skincare: see DIY skincare risks.
