CASEARIA SYLVESTRIS EXTRACT.

Valuable CAS 223748-16-1 / SKIN PROTECTING

A potent botanical extract derived from the Brazilian 'Guaçatonga' tree, engineered to address cellular senescence and structural skin integrity. It serves as a multi-functional bio-active that simultaneously accelerates tissue repair while shielding the extracellular matrix from enzymatic degradation.

Science

Operates through a multi-pathway approach: it inhibits elastase to maintain tissue elasticity, upregulates tropoelastin and lysyl oxidase (LOX) for functional fiber assembly, and provides non-steroidal anti-inflammatory relief by blocking the arachidonic acid cascade. Additionally, it offers broad-spectrum antioxidant protection and antimicrobial biofilm disruption.

Key findings

  1. 01 A 28-day large-scale clinical trial involving 302 participants demonstrated significant improvements in wrinkle depth, moisture retention, and barrier resilience when using concentrations as low as 0.01-1.0%.
  2. 02 In vivo wound-healing models at 2.0% concentration showed accelerated re-epithelialization and enhanced fibroblast activity through improved neovascularization.

Because clinical efficacy is proven at very low thresholds (0.01%), many brands include it at 'label-only' levels. For significant structural anti-aging, look for formulations closer to the 1.0% mark.

Stability

Sensitive to thermal degradation; processing must remain below 45°C. Often encapsulated in block copolymers (like Pluronic F127) or glycolic bases to ensure stability and delivery.

Synergies

  • Hymenaea courbaril
  • Propylene Glycol
  • PEG-400

Conflicts

  • UV Light (photodegradation risk)
  • Strong oxidizing agents
  • High heat (>45°C)
