Science
Mechanism of Action
It functions by inhibiting the Aminopeptidase N (APN) enzyme on the sebocyte membrane. By blocking this specific receptor, it interrupts the peptide signals that trigger oil production, effectively slowing down sebocyte differentiation and reducing overall sebum output at the cellular level.

Key findings
- 01 In vivo testing demonstrated a 42% decrease in sebum secretion over a 28-day period.
- 02 Clinical observations show a visible reduction in both the diameter and total quantity of active pores.
- 03 Research indicates enhanced hair follicle anchoring and reduced scalp oiliness when integrated into trichological formulations.

Dusting Analysis
Because it is an expensive botanical, many brands include it at levels below 0.5% for 'label claims' only. However, clinical data confirms that a minimum of 1% is required to achieve the 42% sebum reduction and pore-refining effects.
The Formula
Formulation
Stability
Highly thermolabile; must be incorporated during the cooling phase at temperatures strictly below 40°C to maintain biological activity.
Synergies
- DHT Blockers
- Niacinamide
- Salicylic Acid
Conflicts
- Strong oxidizing agents
- Temperatures exceeding 50°C
Safety
Safety Profile
While the root extract is stable, formulations are generally capped at 1% in line with Pulegone restrictions found in the related leaf extract to ensure zero sensitization risk.
