What Is Goat Milk?
Goat milk is a natural ingredient derived from goat's milk, used in skincare primarily for its hydrating and conditioning properties. It contains natural proteins, fats and lactose, which work together to draw moisture into the skin and support its natural moisture barrier.
In cosmetic formulations, goat milk functions as a skin conditioner, helping to soften and improve the texture of the skin. It is used in a small proportion of skincare products, typically at low concentrations.
How It Works
Goat milk contains lactose (a natural humectant) and proteins that draw water from the air and deeper skin layers into the outer layers, helping to plump and hydrate the skin. The milk fats also coat the skin's surface, reducing water loss and supporting a healthy barrier function.
Clinical Evidence & References
Research on goat milk in skincare is limited. Most evidence is derived from the ingredient's known chemical composition rather than robust clinical trials in humans. The hydrating properties are consistent with what we understand about milk proteins and lactose, but specific efficacy data comparing goat milk to other hydrating ingredients is sparse.
How to Use
Goat milk is typically found in cleansers, moisturisers and serums. It is generally gentle and can be incorporated into daily routines as part of a hydrating product. Patch test first if you have known sensitivity to dairy products, as allergic reactions are possible.
