Science

This extract exerts its effects through a multi-pronged approach. It offers significant antioxidant protection, courtesy of its high content of isoflavones (such as daidzein and genistein), quercetin, and various phenolic acids (syringic, ferulic, sinapic), which collectively shield skin from oxidative damage. Its phytoestrogenic compounds are instrumental in mitigating visible signs of aging related to sun exposure and estrogen decline, including skin thinning and a crepe-like texture. Genistein, a key flavonoid, exhibits potent anti-inflammatory properties and is proven to inhibit UV-induced redness while stimulating collagen and elastin synthesis. Additionally, the extract's proteins contribute to skin smoothing and softening, with specific small proteins potentially inhibiting pigmentation and delaying hair regrowth. It also fortifies the skin barrier, promotes skin renewal, and enhances overall hydration and nourishment.
