The key molecule involved in maintaining skin moisture is hyaluronic acid (HA), which has a unique capacity to retain water.The regulation of HA metabolism is complex, with multiple sites controlling HA synthesis, deposition, cell and protein associations, and degradation. The enzymes responsible for synthesizing or breaking down HA, along...
