What Is Caprae Lac?
Caprae Lac is goat's milk, included in skincare formulations for its conditioning properties. It contains proteins, lactose, and lipids that can help support the skin's moisture barrier and overall hydration.
Goat's milk has been used in traditional skincare preparations for centuries, and modern formulations incorporate it as a skin conditioning ingredient. It is typically used at low concentrations in finished products.
How It Works
Goat's milk contains lactic acid, which can gently exfoliate the stratum corneum and help improve skin texture. Its protein and lipid content act as humectants and emollients, drawing water into the skin and sealing in moisture.
The ingredient's molecular composition is similar in some respects to human skin lipids, which may contribute to its conditioning effect and skin compatibility.
Clinical Evidence & References
Evidence specifically on Caprae Lac in cosmetic formulations is limited. Most supporting data comes from traditional use and in vitro studies rather than robust clinical trials on human skin.
Lactic acid is well-established as a gentle exfoliant, and goat's milk does contain this compound, though concentrations in skincare products are typically too low for significant chemical exfoliation. Further human studies would help clarify the ingredient's efficacy in modern formulations.
How to Use
Caprae Lac is generally included as part of a finished formulation rather than used as a standalone ingredient. Look for it in cleansers, moisturisers, or masks where it contributes to the overall conditioning profile. Use as directed by the product's instructions, typically daily or as tolerated.
