BERTHOLLETIA EXCELSA FLOWER EXTRACT.

Valuable / SKIN CONDITIONING

Derived from the Amazonian Brazil nut tree, this botanical extract serves as a potent regenerative agent that reinforces the skin's structural integrity. It is particularly valued for its ability to bridge the gap between deep hydration and advanced cellular protection.

Antioxidant Skin conditioning Anti-elastase Collagen booster

Science

This extract operates through a dual-action pathway: it provides high concentrations of selenium to catalyze glutathione peroxidase, an enzyme critical for neutralizing oxidative stress, while simultaneously inhibiting elastase enzymes to prevent the degradation of elastic fibers. It further stimulates fibroblast activity to increase endogenous collagen production, maintaining dermal density.

Key findings

  1. 01 In vitro analysis at 100 µg/mL demonstrated a 62.67% inhibition of elastase and significant fibroblast stimulation within 24 hours.
  2. 02 Studies at concentrations of 50-100 µg/mL confirmed a substantial reduction in Reactive Oxygen Species (ROS) and Nitric Oxide (NO) markers.
