What Is Horse Fat?
Horse fat is a lipid-rich ingredient derived from equine sources, used in skincare formulations as an occlusive emollient. It functions as a skin conditioner, helping to coat and soften the skin surface.
Like other animal-derived fats, it contains a mixture of fatty acids and glycerides that can help reduce transepidermal water loss and create a protective layer on the skin.
How It Works
Horse fat works primarily through occlusion—forming a physical barrier on the skin surface that slows water evaporation. This helps maintain skin hydration and supports the skin's natural moisture balance.
As a lipid-based ingredient, it integrates into the stratum corneum (the skin's outermost layer), enhancing its conditioning properties and creating a smooth application texture.
Clinical Evidence & References
Research specific to horse fat in skincare is limited. Its function as an occlusive emollient is consistent with how other fatty acids and animal-derived oils behave in cosmetic formulations, though direct clinical studies on this ingredient are sparse.
There is some user concern regarding potential comedogenicity and fungal acne compatibility, though systematic evidence evaluating these specific risks for horse fat is not well documented in the scientific literature.
How to Use
Horse fat is typically found in finished formulations rather than as a standalone ingredient for home use. If using a product containing this ingredient, apply to clean, damp skin to help lock in hydration. It may feel occlusive, so start with a small amount and adjust based on your skin's response.
