Science
Mechanism of Action
This ingredient functions as a bioactive delivery vehicle, transporting Andiroba-derived limonoids (like andirobin) and essential fatty acids directly to the skin barrier. Once applied, it inhibits inflammatory pathways such as NF-κB and LTB4, while simultaneously signaling fibroblasts to increase Type III collagen synthesis and accelerate cellular migration for rapid tissue repair.

Key findings
- 01 A 3% concentration was clinically proven to significantly reduce erythema and pain sensations following intense pulsed light (IPL) treatments, showcasing potent analgesic effects.
- 02 In keratinocyte scratch assays, a 10% nanoemulsion achieved 88.9% wound closure, nearly tripling the regenerative rate of the control group.
Transparency
Dusting Analysis
While often used at very low levels (under 1%) as a simple emulsifier, clinical data suggests that a minimum of 3% is required to unlock its analgesic and significant anti-inflammatory benefits.

Formulation
Stability
Maintains high stability in both emulsions and aqueous dispersions; however, extreme pH levels (below 4.0 or above 8.5) may trigger ester hydrolysis.
