In the age of natural skincare and DIY beauty routines, one ingredient gaining traction on social media is tallow—rendered animal fat, typically from beef or lamb. Its proponents claim it's the ultimate moisturizer, loaded with nutrients and similar in composition to human sebum.
But before you slather tallow on your face, it’s crucial to understand the dermatologist’s perspective—and why this popular trend may be doing more harm than good for your skin.
What Is Tallow?
Tallow is a type of rendered fat that has been used for centuries in cooking, soap making, and—more recently—skincare. Its resurgence in the natural beauty space stems from its rich fatty acid profile and vitamins like A, D, E, and K. While it may sound appealing to those seeking “ancestral skincare,” dermatologists urge caution, especially when it comes to using tallow on facial skin.
Why Tallow Might Seem Like a Good Idea—But Isn’t
The natural skincare community praises tallow for its moisturizing properties and nutrient content. However, facial skin is sensitive, and what works on the body—or in history books—doesn’t necessarily work for modern, daily facial care. Here are several reasons why tallow raises red flags in dermatology:
1. Clogged Pores and Breakouts
Tallow is a heavy, occlusive substance, meaning it forms a thick barrier over the skin. While occlusives can help seal in moisture, they can also trap dirt, bacteria, sweat, and dead skin cells—especially on the face, where pores are smaller and more active.
For acne-prone or oily skin types, this can be a recipe for disaster. Tallow may clog pores, leading to whiteheads, blackheads, cystic acne, and overall congestion. In dermatology, we aim to support the skin barrier while allowing it to “breathe,” and tallow’s density works against that goal.
2. Risk of Bacterial Contamination
Unlike pharmaceutical-grade moisturizers or dermatologist-approved skincare products, homemade or small-batch tallow products aren’t always created in sterile environments. Tallow can harbor bacteria if not properly rendered, stored, or preserved.
When applied to the face—especially if there are open pimples, cuts, or microtears—this introduces a risk of infection. It also lacks consistent pH balancing and may disrupt the skin’s natural microbiome, potentially worsening inflammation or irritation.
3. It’s Not Designed for Facial Skin
Facial skin differs from body skin in both structure and sensitivity. Tallow, while potentially beneficial for dry, cracked elbows or heels, is far too rich and comedogenic (pore-clogging) for most facial skin types. This becomes even more concerning for people with:
- Rosacea
- Eczema (facial)
- Hormonal or cystic acne
- Sensitive or reactive skin
These conditions often require lightweight, non-irritating, and tested formulations, not thick animal fats.
4. The Problem with Skincare Fads
Dermatologists encourage patients to take a science-backed approach to skincare. What’s trending online isn’t always safe, effective, or sustainable. Tallow has become a poster child of the “return to nature” skincare movement—but that doesn’t mean it’s right for everyone.
Many of these trends lack rigorous clinical studies, long-term data, and dermatologic testing. Relying on anecdotal evidence—no matter how viral—can result in allergic reactions, flare-ups, or damage to the skin barrier.
5. There Are Better (and Safer) Alternatives
You don’t need to choose between tallow and harsh, chemical-laden products. There are dermatologist-formulated moisturizers that contain:
- Ceramides
- Hyaluronic acid
- Squalane (plant-based and lightweight)
- Niacinamide
These ingredients mimic skin’s natural components without clogging pores or introducing risks associated with animal-derived products.
Final Thoughts: Think Twice Before You Tallow
While we understand the appeal of natural and ancestral skincare, your face is not the place for experimentation with unregulated, untested ingredients like tallow. At our dermatology office, we prioritize evidence-based care and tailor recommendations to your unique skin type, goals, and concerns.
If you're experiencing dry skin, sensitivity, or breakouts, talk to a board-certified dermatologist, PA, and Esthetician instead of turning to TikTok. Your skin will thank you in the long run.
