In 2025, researchers published a cross-sectional analysis of beef tallow skincare claims across social media platforms in the Journal of Cosmetic Dermatology. This is the first peer-reviewed study specifically examining what is being claimed about tallow skincare online and whether those claims align with available evidence. Here is what it found.
What the Study Examined
The researchers analyzed social media posts across platforms, categorizing claims by type, examining whether evidence was cited, and assessing financial bias in content creators. They looked at whether the specific benefits being claimed -- moisturizing, anti-inflammatory, barrier-protective -- aligned with the documented scientific properties of tallow.
Key Findings on the Claims
The most common claims centered on moisturizing, protective, and anti-inflammatory properties, and on improvement in skin conditions including acne, eczema, and psoriasis. The researchers found that these primary claims are consistent with tallow's documented biochemical properties -- the fatty acid composition of tallow that mirrors human sebum, the fat-soluble vitamin content, and the CLA anti-inflammatory activity are documented in the scientific literature.
The researchers noted that the claims made on social media about tallow's basic skin-compatible properties are not unfounded -- they reflect real biochemical characteristics of the ingredient. Where the evidence base is weaker is in specific clinical trial data for skin conditions, which exists for some aspects of tallow but not comprehensively.
The Financial Bias Finding
The study found that over half of social media posts demonstrated financial bias -- the content creator had a commercial relationship with a brand being promoted. Beauty and skincare brands showed the highest financial bias rate (96%), compared to personal channels (55%). Dermatologists demonstrated the lowest financial bias rate (7%).
This finding is worth noting for anyone navigating tallow skincare content. The content with the least financial bias -- dermatologist content -- is also the content most likely to be critical of tallow. The content most aligned with the positive claims is also the content most likely to have commercial motivation. This does not invalidate positive tallow experiences, but it means the most reliable signal is the biochemical evidence and the pattern of consumer outcomes rather than any individual promotional content.
What This Means for Evaluating Tallow Products
The study's broader finding is that tallow's basic claims -- skin compatibility through fatty acid matching, moisturizing through barrier lipid delivery, anti-inflammatory through CLA -- have scientific foundation. What varies enormously between products is the quality of the tallow being used to deliver these benefits. Source animal, diet, rendering method, and additional ingredients determine how much of the documented benefit profile is actually reaching your skin.
