Especially importantly, hyaluronic acid has a special water retention effect and is currently the most moisturizing substance found in nature. It is known as the ideal natural moisturizing factor (NMF), for example, a 2% pure hyaluronic acid aqueous solution can firmly maintain 98% moisture. hyaluronic acid is a multifunctional matrix, and hyaluronic acid (hyaluronic acid) HA is widely distributed in various parts of the human body.
