Science
Mechanism of Action
SODIUM/TEA-UNDECYLENOYL HYDROLYZED SOY PROTEIN operates by forming a protective, moisture-retaining film on the skin's surface, while its smaller protein particles are theorized to penetrate deeper for more profound effects. It is believed to elevate skin cell metabolism, leading to improved tone, radiance, and brightness. Furthermore, it supports the skin's natural anti-aging processes by stimulating collagen synthesis and leveraging soy isoflavones to provide antioxidant protection, combating free radical damage and boosting hyaluronic acid production for superior hydration and reduced fine lines.

Key findings
- 01 Clinical studies demonstrate its efficacy within a 0.5% to 3% concentration range for achieving optimal hydration, enhancing elasticity, and mitigating signs of aging. Biological effects are observed at these low concentrations.
- 02 It effectively soothes irritated skin, diminishes redness and discomfort, and boosts skin cell metabolism, resulting in a more toned, radiant, and brighter complexion. Furthermore, it proactively slows skin aging and regeneratively stimulates collagen synthesis, and has been clinically validated to significantly reduce the appearance of dark circles over an 8-week treatment period.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that soy proteins and peptides, including Hydrolyzed Soy Protein, are safe for use in cosmetics under current practices and concentrations. Testing indicated minimal to no ocular irritation in animal models, and no dermal irritation or sensitization in animal or human subjects, even at concentrations up to 25% for hydrolyzed soy protein. There are no reported instances of Type I immediate hypersensitivity reactions linked to its cosmetic use. The highest reported concentration was 3.5% in mascara.
