Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Locks In Moisture
Traditional Use
The Brazil nut tree has been used by indigenous Amazonian peoples for centuries as a food source and traditional remedy. The oil extracted from Brazil nuts is rich in selenium and has been traditionally valued for nutritional and skin health benefits in indigenous South American medicine.
