Science

Mechanism of Action

This extract functions primarily as a humectant, drawing moisture into the skin's superficial layers to promote softness and smoothness. Its composition, akin to the skin's Natural Moisturizing Factors (NMF), aids in moisture replenishment and strengthens the stratum corneum, thereby reducing transepidermal water loss and bolstering barrier integrity. Furthermore, the peptides within Hydrolyzed Soy Extract form a protective film against external stressors, while its isoflavones and peptides provide antioxidant defense against free radicals, mitigating UV and pollution-induced harm. Evidence also suggests it can stimulate the production of hyaluronic acid and collagen, leading to a reduction in fine lines and wrinkles, improved firmness, and accelerated cell renewal for a smoother skin texture.

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed soy proteins and peptides, including Hydrolyzed Soy Protein, safe for use in cosmetics at current concentrations, with the highest reported cosmetic use being 3.5% in mascara. The FDA also recognizes peptones and soybean protein as Generally Recognized As Safe (GRAS) for certain food-related applications. Despite soy being a common food allergen, the CIR Panel concluded that dermal exposure poses a low risk for immediate hypersensitivity reactions due to its water-soluble nature, low molecular weight preventing IgE cross-linking, and limited skin penetration.
