HYDROLYZED SOYBEAN EXTRACT.

Valuable CAS - / SKIN CONDITIONING

Hydrolyzed Soybean Extract is a peptide and amino acid-rich ingredient derived from soybeans, meticulously processed to enhance its bioavailability for skin. It delivers multi-faceted benefits, including superior hydration, robust antioxidant protection, and support for the skin's natural regenerative processes. This extract is designed to improve skin elasticity, reduce the appearance of dark spots, and bolster overall skin health.

Science

Mechanism of Action

Hydrolyzed Soybean Extract acts by enhancing cellular oxygen consumption and stimulating skin cell turnover. Its inherent isoflavones provide potent antioxidant effects, protecting against photoaging and contributing to the repair of sun-damaged skin. This ingredient actively promotes cell renewal, leading to a reduction in epidermal thickness and roughness. It also stimulates the endogenous production of hyaluronic acid and collagen, bolstering skin firmness and elasticity. Functionally, it delivers vital nutrients, including short-chain peptides and amino acids that mimic the skin's Natural Moisturizing Factors (NMF), effectively binding water to form a moisture-retaining network on the skin surface. This not only aids in deep hydration but also significantly smooths skin texture. Additionally, it reinforces the skin matrix through interaction with keratin and exhibits the capacity to inhibit melanin synthesis.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly assessed the safety of soy proteins and peptides, including Hydrolyzed Soybean Extract. Their reviews, conducted in 2015 and updated in 2024, affirm the ingredient's safety in cosmetic formulations under current use practices and concentrations. The Panel specifically noted that despite soy being a recognized food allergen, dermal exposure to these water-soluble ingredients poses no significant risk of allergic reactions, as they do not penetrate the skin to trigger such a response. Studies reviewed by the CIR demonstrated no instances of skin irritation or allergic reactions in either animal or human subjects. The SCCS (Scientific Committee on Consumer Safety) has not established any specific restrictions for soy peptide ingredients within the EU. While the FDA mandates allergen labeling for soy in food products, this regulation pertains to ingestion, not topical cosmetic application.
