Summary

Antioxidant Skin-Conditioning Agent Emollient Smoothing Softening Anti-inflammatory Brightening (inhibits pigmentation) Protective against UV-induced redness

Science

Mechanism of Action

Glycine Soja Seed Extract actively protects the skin by neutralizing free radicals, primarily due to its high concentration of phenolic acids and flavonoids. It fortifies the skin's moisture barrier, leading to improved hydration and elasticity, and stimulates collagen production. Its genistein content offers anti-inflammatory benefits, effectively reducing UV-induced redness. Furthermore, it contributes to skin brightening by inhibiting melanosome transfer, preventing melanin pigment from surfacing. The extract's phytoestrogens mimic natural estrogen activity, which is particularly advantageous for mature skin by improving firmness and reducing dryness, while also supporting cellular repair and regeneration through its protein profile.

Typical usage for general cosmetic benefits ranges from 0.09% to 3%, with the highest reported concentration in face and neck products being 2%. While observed in some shampoos at 0.02%, concentrations below 0.09% in leave-on skincare products are unlikely to provide significant, comprehensive skin benefits and may indicate a 'dusting' practice for marketing purposes.
