BASSIA BUTYRACEA SEED BUTTER.

Valuable / SKIN CONDITIONING

Commonly known as Chiuri butter, this nutrient-dense botanical lipid is harvested from the Himalayan butter tree to provide intensive barrier repair. Its unique fatty acid profile offers a high-melting point alternative to traditional plant butters, delivering superior occlusive protection and restorative properties for compromised skin.

Science

It functions as a high-performance occlusive emollient, creating a breathable yet protective lipid film that significantly reduces transepidermal water loss (TEWL). Rich in palmitic (50-60%) and oleic (30-40%) acids, it re-integrates into the stratum corneum to stabilize the lipid bilayer while delivering bioactive triterpenoids and Vitamin E to soothe inflammation and neutralize oxidative stress.
