Science
Mechanism of Action
This ingredient actively tones, soothes, and offers robust antioxidant protection to the skin. It functions by reducing inflammation, stimulating microcirculation, and regulating excessive oil production, making it particularly beneficial for oily and combination skin types. Its rich profile of active compounds, including rosmarinic acid, flavonoids, phenolic acids, and diterpenes, synergistically neutralize free radicals, thereby shielding the skin from environmental damage and mitigating signs of premature aging. Furthermore, it promotes regenerative processes, exhibits antibacterial and astringent properties, acts as a humectant to minimize water loss, and helps visibly constrict pores.
