Science
Mechanism of Action
This extract operates through several key pathways: it significantly neutralizes free radicals and inhibits oxygen-promoted reactions, offering antioxidant protection against environmental stressors, including UV light. As a humectant, it attracts and retains moisture, optimizing skin hydration and enhancing barrier function. Its anti-aging efficacy stems from inhibiting collagenase, elastase, and hyaluronidase—enzymes responsible for degrading collagen, elastin, and hyaluronic acid, thereby mitigating concerns like sagging, wrinkles, and elasticity loss. Furthermore, it contributes to skin brightening by regulating melanogenesis and inhibiting tyrosinase, which helps to diminish dark spots and even skin tone. It may also offer antimicrobial properties.

The Formula
Formulation
Stability
This water-soluble hydrolysate demonstrates optimized solubility and antioxidant activity of its phenolic acids within a pH range of 3.3 to 5.0, with specific studies noting an ideal pH of 4.4. For safety, formulations must restrict peptides to a weight-average molecular weight of 3500 Da or less, or ensure polypeptide lengths do not exceed 30 amino acids. It should not be applied to damaged skin or products intended for mucosal contact (eyes, airways) if peptide length restrictions are not strictly followed. Good manufacturing practices are essential to minimize impurities. The ingredient can also enhance the stability of cosmetic emulsions. Dried extracts may benefit from carriers like maltodextrin, inulin, or gum arabic for enhanced stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that hydrolyzed wheat protein (and related hydrolysates) is safe for cosmetic use, provided it is formulated to restrict peptides to a weight-average molecular weight of 3500 Da or less, or ensures polypeptide lengths do not exceed 30 amino acids. The Scientific Committee on Consumer Safety (SCCS) also affirmed its non-irritant status for skin and eyes under proper formulation. However, if these peptide restrictions are not met, there is a potential for inducing sensitization or Type 1 immediate hypersensitivity reactions. Consequently, it should not be used on damaged skin or in products that might contact mucosal surfaces (eyes, airways) if peptide lengths are not properly controlled. Adherence to good manufacturing practices is crucial to address potential concerns regarding pesticide residues and heavy metals.
