Science
Mechanism of Action
It functions as a TRPV1 modulator, effectively raising the skin's tolerance threshold to external triggers like heat or chemical irritants. Beyond its neuro-soothing capabilities, the extract utilizes bio-active flavonoids (nobiletin and tangeretin) to inhibit NF-κB inflammatory pathways and utilizes natural fruit acids to promote non-aggressive desquamation and sebum regulation.

Clinical Evidence

Key findings
- 01 Demonstrated immediate relief (under 5 minutes) from lactic acid-induced stinging at 1-4% concentrations.
- 02 A 7-day continuous application study showed significantly enhanced skin tolerance via TRPV1 inhibition.
- 03 Suppression of TRPV1 protein expression was observed at concentrations as low as 0.25%.
Transparency
Dusting Analysis
While often used at trace levels for fragrance or marketing appeal, clinical efficacy for sensitive skin requires a minimum of 0.25% to influence protein expression, with 1% preferred for immediate symptomatic relief.
The Formula
Formulation
Stability
Active flavonoid recovery is optimized in alcohol-based or oil-miscible environments, though aqueous extracts remain functional for mineral and fruit acid delivery.
Synergies
- Vitamin C
- Niacinamide
- Hyaluronic Acid
Conflicts
- High-dose phototoxic furanocoumarins (must be restricted below 15ppm)
- High-concentration monoterpenes
Safety
Safety Profile
Safety is contingent on the removal or limitation of 5-methoxypsoralen (5-MOP) to below 0.0015% in leave-on products to prevent photosensitivity.
