Frequently Asked Questions
What is Brazilian Nut Shell Oil?
Brazilian Nut Shell Oil is a lightweight oil extracted from the outer shells of Brazil nuts (Bertholletia excelsa). It is rich in polyphenols, flavonoids, vitamin E, and essential fatty acids, and is used primarily as a topical cosmetic ingredient for skin and hair care.
Is Brazilian Nut Shell Oil safe to use on sensitive skin?
It is generally well-tolerated for topical use, but a patch test is recommended before first application, especially for individuals with sensitive skin or tree nut allergies. Discontinue use if irritation occurs. It is not intended for oral consumption.
How does Brazilian Nut Shell Oil differ from regular Brazil nut oil?
Regular Brazil nut oil is pressed from the nut kernel and is edible, with a higher fat and selenium content. Shell oil is extracted from the outer pericarp and is richer in polyphenols, tannins, and flavonoids, making it more suited for topical antioxidant and anti-inflammatory applications rather than dietary use.
