Aleurites Moluccanus (Kukui) Extract

What is Aleurites Moluccanus (Kukui) Extract?

Aleurites Moluccanus Extract, known as Kukui Extract, derives from the seeds of the Aleurites moluccanus tree, a species native to Hawaii and Pacific islands. This botanical ingredient serves as a skin conditioning agent in cosmetics like creams, lotions, and serums. Its composition features fatty acids including linoleic, oleic, and palmitic acids, which replicate skin's lipids to lubricate and soften the surface, filling in irregularities for a smoother feel. The astringent action stems from mild tannins that contract superficial proteins, yielding a refined, less oily look. In products, it enhances slip during application and aids in maintaining hydration by supporting the barrier function alongside other agents, suitable for various skin types without heavy residue.
