BERTHOLLETIA EXCELSA SEED OIL

Description

Bertholletia excelsa seed oil, commonly known as Brazil nut oil, is a nutrient-rich emollient derived from the seeds of the Bertholletia excelsa tree native to South America. This golden-hued oil is prized for its high content of selenium, a powerful antioxidant that helps protect skin cells from oxidative stress and environmental damage.

The oil is composed primarily of long-chain fatty acids, including oleic, linoleic, and palmitic acids, which contribute to its excellent moisturizing and skin-conditioning properties. These fatty acids help strengthen the skin barrier, reduce transepidermal water loss, and improve overall skin elasticity.

Bertholletia excelsa seed oil is particularly beneficial for dry, mature, or sensitive skin types. Its emollient nature helps soothe irritation and inflammation while providing deep hydration. The oil's vitamin E content further enhances its antioxidant properties, promoting skin cell regeneration and reducing the appearance of fine lines and wrinkles.

In skincare formulations, this oil is typically used in concentrations ranging from 1% to 5%, depending on the desired effect and product type. It is compatible with most cosmetic ingredients and can be incorporated into various skincare products, including facial oils, serums, and moisturizers.
