Creatine
What is Creatine?
Creatine is a naturally occurring nitrogenous organic acid synthesized in the human body from amino acids including glycine, arginine, and methionine. It functions as a key player in cellular energy storage by binding phosphate to form phosphocreatine. In cosmetic products, creatine is classified as a skin conditioning agent and humectant, typically incorporated into moisturizers, creams, serums, and lotions. It works by attracting and holding water molecules to the skin's surface and within the stratum corneum, thereby aiding in the maintenance of skin's moisture balance. This humectant property contributes to preserving the skin barrier's integrity, enhancing tactile qualities like softness and suppleness without pore-clogging potential. Its water-soluble nature allows for straightforward formulation and compatibility with various skincare vehicles.
