Science
Mechanism of Action
This dipeptide functions primarily by supporting essential metabolic processes within the skin. L-lysine, one of its constituents, is critical for stimulating collagen synthesis, which in turn promotes skin elasticity and firmness, while also imparting direct moisturizing benefits. L-glutamic acid complements this action by bolstering the skin's antioxidant capacity and contributing to overall protein synthesis. The inherent charged groups within Lysine Glutamate facilitate its water solubility and enable crucial ionic interactions, ensuring optimal delivery and integration into biological systems.
