Beef tallow, traditionally valued for its culinary applications, is experiencing a resurgence, not only in the kitchen but also in skincare routines. This rendered form of beef fat, a byproduct of the meat industry, is being touted by some influencers and wellness enthusiasts as a natural moisturizer with various skin benefits. Simultaneously, it's gaining traction within the carnivore diet community due to its rich taste, high smoke point, and long shelf life. But is beef tallow truly a skincare superstar and a carnivore diet essential? Let's explore its potential benefits, drawbacks, and uses, considering perspectives from experts and users alike.
What is Beef Tallow?
Beef tallow is derived from melting and clarifying fatty tissue from cows, typically suet (the hard fat around the kidneys and loins) or other fatty trimmings. This process transforms the fat into a golden, shelf-stable oil that solidifies at room temperature. Tallow is distinct from lard, which is derived from pigs. Ermias Kebreab, a professor of animal science at UC Davis, notes that utilizing beef tallow aligns with efforts to minimize waste by using the whole animal.
Types of Tallow
There are different types of tallows, but 3 most common types of tallow are beef, grass-fed, and deer:
- Beef Tallow: Rendered fat from beef, typically sourced from suet around the kidneys and loins of cattle. It is widely used in cooking for frying and baking due to its high smoke point, adding a mild beefy flavor to dishes. It can also be used to make candles, soaps, and skincare products.
- Grass-Fed Tallow (Organic Tallow): Derived from cattle fed with grass rather than grains, making it more nutritious and eco-friendly. It boasts higher levels of vitamins A, D, E, and K2, as well as omega-3 fatty acids and conjugated linoleic acid (CLA) compared to regular beef tallow.
- Deer Tallow: Made from deer fat, it tends to be softer in texture compared to beef tallow.
The Allure of Beef Tallow in Skincare
Proponents of beef tallow skincare highlight its composition of nourishing vitamins and fatty acids, suggesting a range of cosmetic and medicinal benefits. Adam Friedman, a dermatology professor and chair at GW School of Medicine and Health Sciences, explains that beef tallow contains saturated and unsaturated fats, such as palmitic acid, stearic acid, and oleic acid. These fats are naturally present in human skin and can potentially reinforce the skin's barrier, lock in moisture, and soften the skin. Beef tallow also contains fat-soluble vitamins A, D, E, and K, which may provide additional antioxidant and skin-supporting benefits. Theoretically, beef tallow could mimic the skin's natural lipids, replenishing the external barrier, reducing water loss for improved hydration, and calming inflammation.
Potential Skincare Benefits: A Closer Look
- Deep Moisturization: Tallow's fatty acids, similar to those in human skin, allow it to penetrate deeply, hydrating and repairing the skin barrier.
- Nutrient-Rich Composition: Vitamins A, D, E, and K contribute to skin cell turnover, repair, growth, and protection against damage.
- Anti-Inflammatory Properties: Vitamins A and E, along with tallow's fatty acid composition, can soothe irritated skin and reduce inflammation associated with conditions like eczema and psoriasis.
- Antioxidant Protection: Vitamin E and other antioxidants neutralize free radicals, protecting the skin from environmental stressors and premature aging.
The Skepticism of Dermatologists
Despite the enthusiasm surrounding beef tallow, dermatologists remain cautious, citing a lack of robust clinical evidence to support the claims of glowing skin, acne cures, and Botox-like firmness. Rajani Katta, a board-certified dermatologist and clinical professor at the University of Texas Houston, emphasizes that the trend's popularity has outpaced the scientific research. A 2024 literature review indicates that beef tallow offers hydrating and moisturizing properties, but the optimal composition and effectiveness remain unclear. The review also points out significant research gaps regarding the short- and long-term effects of tallow on human skin.

Quality Concerns and Potential Risks
Friedman points out that the absence of FDA regulation for beef tallow as a skincare product raises concerns about sourcing and processing. Improperly sourced or processed tallow may carry a risk of pathogen or pesticide contamination. Samantha Karlin, a board-certified dermatologist, notes that some individuals may experience breakouts or allergic reactions due to sensitivity to animal-derived products or acne-prone skin.
Potential Side Effects
- Allergic Reactions: Individuals with sensitive skin may react to certain components in tallow products.
- Changes in Skin pH: Tallow soaps, with a higher pH than healthy skin, may disrupt the skin's natural balance and lead to dryness with excessive use.
- Temperature Sensitivity: Exposure to high temperatures can cause tallow to separate and become grainy.
Responsible Use and Alternatives
For those determined to try beef tallow, Friedman advises caution: start with a small amount, source responsibly, use moderately, and monitor the results. He also emphasizes the existence of well-established and verified skincare options.
Beef Tallow in the Carnivore Diet
Beyond skincare, beef tallow is gaining popularity within the carnivore diet community. This dietary approach, centered around animal products, values beef tallow for its unique properties and potential health benefits.
Beef Tallow Used For:
- High-heat cooking
- Greasing cast-iron pans
- Making savory pie crusts and biscuits
- Non-food uses: candles, soaps, moisturizers
Advantages for Carnivore and Keto Diets
- Fat-Based Metabolism: Tallow provides a reliable energy source for those relying on fat as their primary fuel.
- Absence of Carbohydrates and Seed Toxins: Tallow aligns with the carnivore diet's emphasis on whole, animal-based foods, free from carbohydrates and plant-based toxins.
- Inflammation Reduction: Low omega-6 levels in tallow can contribute to hormonal balance and joint health.
- Nutrient Absorption: Saturated fats in tallow may enhance the absorption of fat-soluble vitamins, crucial for those avoiding plant-based foods.
- Increased Satiety: Tallow's fat content promotes longer-lasting satiety compared to vegetable oils.
Is Beef Tallow Healthy or Unhealthy?
While saturated fat consumption has been a subject of debate, recent research suggests that saturated fats like those in beef tallow may not be as detrimental as previously thought, especially within a whole-food, unprocessed diet. Stearic acid, a component of tallow, may even help lower LDL cholesterol. Choosing grass-fed tallow and avoiding its combination with ultra-processed carbohydrates can further enhance its potential health benefits.

Sourcing and Making Beef Tallow
Beef tallow can be purchased ready-made from reputable brands or rendered at home. When buying, look for labels indicating "grass-fed," "non-bleached," or "pasture-raised." Avoid tallow mixed with seed oils or preservatives. To make tallow at home, slowly cook small chunks of beef fat in a heavy-bottomed pot over low heat, strain the rendered fat, and store it in the refrigerator or freezer.
Distinguishing High-Quality Tallow
To ensure the quality of tallow, consider the following:
- Odor: High-quality tallow has a mild, neutral scent. A strong or unpleasant odor may indicate poor quality or spoilage.
- Texture: Tallow should be solid at room temperature but soften when warmed. A grainy or lumpy texture may indicate improper rendering.
- Ingredients: Pure tallow products should contain only rendered fat, without additives. Check for potential allergens if additional ingredients like essential oils are present.
