Lysine Carboxymethyl Cysteinate
What is Lysine Carboxymethyl Cysteinate?
Lysine Carboxymethyl Cysteinate is a synthetic ingredient formed by combining the amino acids lysine and a carboxymethyl-modified cysteine. This creates a water-soluble compound stable in cosmetic formulations. Primarily categorized as a conditioning agent, it appears in skincare products like creams, lotions, and serums, as well as haircare items. In formulations, it functions by forming a lightweight film on the skin's surface, which helps lock in moisture and enhances the skin's barrier. This action promotes a supple texture and flexibility without heaviness. Its humectant properties draw water to the skin, supporting hydration, while its mild profile suits daily use in rinse-off and leave-on products, aiding overall skin comfort.
