Mechanism of action
Paeoniflorin (a monoterpene glucoside) inhibits tyrosinase via competitive inhibition at the copper-containing active site, reducing melanin synthesis. Also inhibits NF-κB activation and TNF-α production, providing anti-inflammatory activity. The dual brightening + soothing mechanism makes it useful in combination eye cream formulations.
Clinical evidence · Emerging

In vitro tyrosinase inhibition studies and anti-inflammatory mechanism characterisation. Limited clinical data for cosmetic application.

Effective concentration range
0.5–2%
Formulation notes
Aqueous or hydroalcoholic extract; paeoniflorin content varies. pH stable in cosmetic range.
Watchouts
Clinical evidence for cosmetic use is limited. Paeoniflorin concentration in finished products is difficult to verify without standardisation data.
Market positioning
Marketed as TCM botanical brightener and soother. Tyrosinase inhibition mechanism is credible; clinical translation to visible brightening at cosmetic concentrations requires independent validation.
