BERTHOLLETIA EXCELSA PERICARP EXTRACT.

Valuable / SKIN CONDITIONING

A potent botanical extract derived from the protective outer shell of the Brazil Nut, engineered for advanced cellular defense and structural integrity. This multifunctional bioactive offers a dual-action approach to skincare by neutralizing oxidative stress while actively stimulating the dermal matrix.

Antioxidant Collagen Booster Astringent Skin Conditioning

Science

This extract operates through a complex assembly of Selenium, flavonoids, and tannins. Selenium serves as a critical cofactor for antioxidant enzymes that protect human DNA from UV-induced damage, while phenolic compounds suppress elastase activity—the enzyme responsible for degrading elastic fibers. Simultaneously, its tannin content provides a gentle astringent effect, refining skin texture and reducing inflammatory markers.
