Beef tallow moisturizer is a viral social media trend gaining traction in the sector due to its reported skin-enhancing benefits and natural formulation. However, the industry has yet to place it on the clean and sustainability scale due to the potential ethical and safety concerns linked to its animal origins. Tallow, or “rendered fat,” is the fatty tissue surrounding an animal’s organs that has been removed, heated, and clarified. It is typically white and hard at room temperature. It is often used in cooking, frying, or as a flavor enhancer, but it also has heritage roots in ancestral skin care.
