European clinical research shows that soy ECM has potent cell stimulating effects which result in skin firming action; improved elasticity. One of the secrets of ECM is its unique set of genistein-rich isoflavones which have estrogen-like properties, particularly valuable for mature women. Diminishes dryness, smoothes texture, improves radiance.The soy serum's role in skin firming is explained this way: sun damaged skin has rupture of collagen fibres and functionally impaired fibroblasts (the stimulants to collagen production). Clinical research concludes that ECM can influence and stabilize fibroblasts via almost incredible "growth signals" --- and thus increase collagen and elasticity.
