Science
Mechanism of Action
Caprae Butyrum functions as a high-performance occlusive and emollient that mimics the skin's natural lipid structure. Its medium-chain triglycerides (Caproic, Caprylic, and Capric acids) integrate into the stratum corneum to repair the barrier, while smaller fat globules facilitate the efficient delivery of fat-soluble vitamins (A, D, E, and K). Additionally, natural lactic acid precursors provide a gentle keratolytic effect, promoting cellular turnover.

Key findings
- 01 Demonstrated significant epidermal nourishment and enhanced skin conditioning in mature skin through enzymatic regeneration.
- 02 Analysis confirms superior absorption profiles over bovine fats due to reduced globule size, enhancing vitamin delivery.

Dusting Analysis
Due to its premium status and 'milk' marketing appeal, it is often included at negligible levels (<0.5%) for label claims. However, clinical benefits for barrier repair and nourishment require a concentration of at least 2%.
