Science

Mechanism of Action

This extract operates through several key mechanisms to optimize skin health, particularly for individuals with excess oil and blemish concerns. Its primary action is astringent, effectively tightening pores and reducing their visible appearance. Crucially, studies indicate its capacity to inhibit 5α-reductase activity, thereby decreasing testosterone conversion and subsequent sebum synthesis in sebocytes. This targeted inhibition contributes significantly to oil control and anti-acne efficacy. Furthermore, Quercus Acutissima Extract delivers antimicrobial, anti-inflammatory, and antioxidant benefits due to its rich composition of flavonoids and phenolic compounds, aiding in soothing irritation and protecting the skin.
