Science
Mechanism of Action
This ingredient functions as a potent antioxidant, neutralizing free radicals and mitigating oxidative stress that contributes to premature aging, fine lines, and wrinkles. It significantly improves skin conditioning by enhancing the skin's natural barrier, primarily through stimulating filaggrin production, which is crucial for maintaining moisture and protecting against transepidermal water loss (TEWL). As a humectant, it attracts and retains moisture, boosting the skin's Natural Moisturizing Factors (NMF) and reducing flaking. Additionally, it forms a protective film on the skin's surface, contributing to a perceptibly smoother and softer feel.

Formulation
Stability
Oxidation of peptides containing cysteine, methionine, or tryptophan, and degradation of those with asparagine or glutamine, can affect the stability of wheat germ hydrolysates. Optimal stability is observed within a pH range of 4.0-5.0.
Conflicts
- Not recommended for use on damaged skin, in products that may contact mucous membranes, or be incidentally inhaled, particularly if peptide lengths exceed 30 amino acids (approximately 3.3 kDa).
- Individuals with diagnosed gluten sensitivity should avoid products containing this ingredient.
Safety
Safety Profile
The CIR Expert Panel concluded that hydrolyzed wheat protein and gluten are safe when formulated to restrict peptides to an average molecular weight of 3500 Da or less (or approximately 30 amino acids/3.3 kDa). Exceeding this peptide length can pose a risk of Type 1 immediate hypersensitivity reactions. Ocular and dermal irritation studies indicate low irritancy. However, it should not be used on damaged skin or in products that might lead to mucous membrane contact or incidental inhalation. While generally recognized as safe by the FDA as a food substance, individuals with gluten sensitivity should exercise caution.
