Science

Mechanism of Action

This extract derives its efficacy from a diverse array of bioactive compounds, including flavonoids, polyphenols, iridoids, triterpenoids, and saponins. These constituents, similar to those found in other parts of the Lonicera japonica plant, actively neutralize free radicals to prevent oxidative stress and premature aging. It calms inflammation by inhibiting pathways such as COX-1,2, TNF-α, and IL-β, while its antibacterial qualities combat acne-causing bacteria and provide natural preservation by impeding microbial proliferation.
