Science
Mechanism of Action
LYSINE PCA functions primarily as a potent humectant and skin conditioning agent. Its Pyrrolidone Carboxylic Acid (PCA) component is a key constituent of the skin's Natural Moisturizing Factor (NMF), actively binding water to enhance and sustain skin hydration. Simultaneously, the Lysine component, an essential amino acid, plays a critical role in promoting collagen production, which is fundamental for maintaining skin's elasticity and firmness. It also exhibits antistatic properties.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded LYSINE PCA and other PCA salts as safe for use in cosmetic formulations as of 1999. It is crucial to avoid co-formulation with N-nitrosating agents. L-amino acids, including lysine, are also recognized as Generally Recognized As Safe (GRAS) by the FDA for direct food additive use, further supporting its safety profile.
