Science

Mechanism of Action

Acting through multiple pathways, this ferment filtrate delivers gentle exfoliation and enhanced moisturization due to its lactic acid content. Salicylic acid and salicin contribute significant anti-inflammatory and antimicrobial properties, effectively aiding in pore decongestion. It functions as a robust antioxidant, actively protecting the skin from oxidative stress and environmental aggressors. The ingredient also plays a crucial role in strengthening the skin barrier, calming irritation, and fostering a balanced skin microbiome by creating an environment less hospitable to harmful microorganisms. Furthermore, its humectant qualities improve hydration, it helps regulate sebum production, refines the appearance of pores through astringent effects, and stimulates vital cellular renewal and repair processes.
