Science

Mechanism of Action

This ingredient operates via its rich composition of isoflavones (such as genistein, daidzein, and glycitein), peptides, and free amino acids. It functions as a robust antioxidant, providing photoprotective effects that shield skin keratinocytes from UVB-induced damage and inflammation. Mechanistically, it enhances skin hydration by upregulating hyaluronan (HA) and improving barrier function through the reduction of Hyal2 expression in dermal fibroblasts. It also helps to recover UVB-induced downregulation of critical barrier genes including filaggrin, loricrin, and AQP3. Furthermore, compounds like daidzein and genistein actively increase collagen and hyaluronan levels, decrease matrix metalloproteinase (MMP) expression, and stimulate fibroblast proliferation, promoting skin cell regeneration and contributing to improved skin gloss and softness.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed soy proteins and peptides, including related Hydrolyzed Soy Protein, as safe for cosmetic use up to 25% concentration. It was found not to be a dermal irritant or sensitizer in human studies at this level. However, a specific case report indicated an aggravation of rosacea in one patient after using soy-containing facial products, suggesting a potential localized sensitivity for those with rosacea.
