Science
Mechanism of Action
This extract leverages a high concentration of polyphenols and flavonoids, including rutin and hydroxycinnamic acids, to neutralize reactive oxygen species (ROS) induced by UV and pollution. Its unique evolution as a desert-dwelling species allows its bark to synthesize compounds that facilitate water storage and cellular protection, which translate to improved barrier integrity and skin conditioning when applied topically.

Clinical Evidence

Key findings
- 01 Clinical evaluation of cultured plant gums showed that concentrations between 1.0–3.0% provide measurable structural stability and humectant benefits in topical applications.
- 02 In vitro studies at 50 µg/mL demonstrated a significant, dose-dependent reduction in oxidative stress markers without inducing cytotoxicity in dermal cells.
Transparency
Dusting Analysis
Because it is an exotic botanical, many brands include it at 'label-only' concentrations (below 0.1%) to claim 'desert plant' benefits. To achieve the documented humectant and structural stability effects, a concentration of at least 1.0% is required.
The Formula
Formulation
Stability
Highly resilient across a wide pH spectrum; however, it is thermolabile and should be added during the cooling phase below 40°C to prevent the degradation of natural polysaccharides.
Synergies
- Hyaluronic Acid
- Vitamin E
- Niacinamide
Conflicts
- Strong oxidizing agents
- High heat (>40°C)
Safety
Safety Profile
Listed in the EU CosIng database as a safe skin-protecting agent. Generally tolerated well at standard botanical usage levels.
