Science
Mechanism of Action
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.

Safety
Safety Profile
The CIR Expert Panel has determined Glycine Soja Seedcake Extract, along with 23 other soy-derived ingredients, to be safe for cosmetic use within current industry practices and concentrations. The highest reported concentration for use in face and neck products is up to 2%. It holds approval from the EU COSING database for its skin conditioning functions. With a low hazard rating (typically 1) from EWG, concerns for irritation, sensitization, or toxicity are minimal at typical concentrations of 0.1-2%. Human Repeat Insult Patch Tests (HRIPTs) conducted with up to 3% concentration showed no irritation or sensitization. A study on its ocular irritation potential demonstrated negligible cytotoxicity, with an IC50 greater than 50%.
