What factors determine the absorption of hyaluronic acid 1. The first time you play will be absorbed faster. When hyaluronic acid is injected into the skin for the first time, the skin cells will absorb the foreign substance relatively quickly. At the same time, hyaluronic acid will absorb the water in the skin, and the skin will become very hydrated and full, at this time, the cells will not absorb so fast when the needle is replenished again (there is a limit to absorption), so the maintenance time of hyaluronic acid will become longer after replenishing the needle several times. 2, the injection site and expression activity, the injection site also determines the hyaluronic acid maintenance time. Parts like nose and chin have a relatively longer maintenance time because there are no active muscles, while the lip and nose furrow, apple muscle and lips are the areas of our face that are often active, so the time will also be shorter. 3, individual conditions, including fat and thin, age and their own metabolic rate can affect the metabolic rate of hyaluronic acid. Generally speaking, the absorption rate of hyaluronic acid after injection is faster for thin physique than fat physique, and the metabolism time is also different for people of different ages who inject the same dose of hyaluronic acid in the same area. As the older the skin itself contains low hyaluronic acid, the metabolism after injection is faster compared to younger skin, and the maintenance time will be shorter. 4.The difference of products. Unlike Botox, there are only two kinds of hyaluronic acid that are legal in China. There are many kinds of hyaluronic acid of various molecular weight, various brands and various origins in the medical beauty market. A good hyaluronic acid lies in its process, quality and maintenance time. If you want to maintain it for a long time, good hyaluronic acid is the first choice, but it still depends on your own economic conditions, no one forces you to play expensive ones. Secondly, it is also important to choose the right molecular weight of hyaluronic acid to be injected in different parts of the body, which depends on qualified and experienced doctors to keep an eye on the situation. 5.Personal habits: staying up late and drinking alcohol will lead to the doubled and accelerated absorption of hyaluronic acid. Staying up late causes skin dehydration, hyaluronic acid is like water in the skin, when the dehydrated muscle will absorb a lot of hyaluronic acid; when the skin is dry and dehydrated, hyaluronic acid is also absorbed faster, so drink more water after injection; drinking will accelerate blood circulation, hyaluronic acid will be lost faster. 6.Psychological effect. After a week to half a month, many people think that hyaluronic acid has been absorbed, but in fact, hyaluronic acid is still there, and it will continue to absorb the water in the skin and grow bigger.
