Functional Application in Cosmetics

Genistein is a phytoestrogenic isoflavone widely incorporated in modern formulations targeting firmness, photoexposed skin, and oxidative imbalance. Its affinity for estrogen receptors in the skin makes it highly relevant for mature skin support, tone recovery, and vitality-focused concepts.

• Firmness & Density: Supports skin’s natural resilience in aging care formulations
• Photoprotection Support: Often used in sun-exposed or stressed skin lines
• Phytoactive Origin: Clean-label positioning with proven dermocosmetic relevance
• Hair Care Applications: Enhances scalp balance and fortifies fiber structure

Commonly applied in skin-firming serums, night emulsions, firming eye treatments, and anti-fatigue scalp products. Supplied in bulk format with documentation for B2B use.
