Regarding hyaluronic acid, the research directions worthy of everyone's attention in the future mainly include the following four:

(1) The first is to allow 40,000 molecular weight polysaccharide hyaluronic acid to enter cells. This is not recognized by the original traditional knowledge. According to conventional thinking, it is impossible. However, it has been proved by experiments that the polysaccharide hyaluronic acid with a molecular weight of 40,000 can enter cells, which means that its function and What it used to do outside the cell or on the skin's surface is completely different. Based on this, we can study its protective effects on cells, including anti-oxidation, scavenging free radicals, prolonging activity, and anti-aging.

(2) The second direction is the role of hyaluronic acid in preventing tumor cell division and metastasis. An animal experiment in the United States found that the reason why some animals are free of cancer is not because they do not have tumor cells in their bodies, but because the concentration of hyaluronic acid around the tumor cells is particularly high, and the molecular weight is also large. Is it because the large molecular weight and network structure of hyaluronic acid lock the tumor cells, so that the tumor cells cannot move and can coexist, but will not form cancer? Because with the reduction of the human body's metabolic capacity, the synthesis ability of hyaluronic acid in the body also deteriorates. Compared with the 60-year-old and 20-year-old, this synthesis ability is reduced to 1/4. At this time, the molecular weight and content of hyaluronic acid in the body are lowered. Is it because when the synthesis ability of hyaluronic acid is strong, the locked tumor cells are not easy to spread, and once the hyaluronic acid cannot lock the tumor cells, it will differentiate and metastasize, thus forming cancer? Of course, these inferences still need to be further verified by scientific research practice.

(3) The third research direction is anti-cancer drugs or vaccines. Cancer vaccines all need a guidance system on small molecules, and polysaccharide is a good guidance system, not limited to hyaluronic acid, there may be other polysaccharides. When this anticancer drug or vaccine is hooked up to a guidance system, it will focus on the tumor cells in a targeted manner. If it can enter the cell membrane, the anti-cancer drugs can be directed into the tumor cells. How to use hyaluronic acid as a guidance system to make anticancer drugs or vaccines is a great direction.
