BUTEA SUPERBA EXTRACT.

Optional / SKIN CONDITIONING

A flavonoid-rich botanical extract from the Thai medicinal plant that functions as a dual-action skin enhancer. Through phosphodiesterase inhibition and potent antioxidant activity, it promotes microcirculation while protecting structural proteins from free radical damage. Clinical applications demonstrate measurable improvements in skin firmness and wrinkle reduction at concentrations as low as 2%.

Science

Contains bioactive flavonoids (butrin, isobutrin) and beta-sitosterol that inhibit phosphodiesterase enzymes, promoting vasodilation and enhanced blood flow to skin tissues. Simultaneously functions as a free radical scavenger, protecting collagen and elastin from oxidative degradation while supporting cellular regeneration processes.
