Science

Mechanism of Action

This extract operates through multiple pathways to benefit the skin. Its rich composition of flavonoids and tannins provides robust antioxidant activity, protecting cellular integrity from free radical damage. A key active compound, pedunculagin, significantly inhibits the production of inflammatory cytokines (IL-6, IL-8) and chemokines, thereby mitigating redness and irritation. Furthermore, it exhibits potent 5α-reductase type 1 inhibitory activity, which is crucial for managing acne by reducing dihydrotestosterone (DHT) levels and subsequent sebum overproduction. Pedunculagin also promotes keratinocyte regeneration, contributing to a stronger skin barrier.

Key findings

  1. 01 In in-vitro studies, Quercus mongolica extract and its primary compound, pedunculagin, demonstrated potent inhibition of nitric oxide production and a decrease in inflammatory cytokines (IL-6, IL-8), alongside significant 5α-reductase type 1 inhibitory activities.
  2. 02 Research on UVB-irradiated human skin cells and keratinocytes confirmed the extract's capacity to inhibit the production of inflammatory cytokines and chemokines.
  3. 03 Studies on phenolic compounds from a related Quercus species (Quercus acutissima) also showed strong antioxidative, anti-inflammatory, and anti-acne effects, including 5α-reductase inhibition, in in-vitro cell models.
