1, varies from person to person Just like two people drink water at the same time when they are thirsty, one person is not thirsty after drinking a cup of water, while the other person, need to drink 2 cups of water, and feel thirsty again soon after drinking. The speed of absorption after hyaluronic acid injection is related to individual physical conditions. Generally speaking, thin people absorb it faster than fat people because the metabolic rate of thin people’s body is a bit higher. Older than younger absorb faster, because the older the body itself hyaluronic acid content is less, after playing hyaluronic acid, absorption is relatively fast. 2, the first time to play hyaluronic acid, fast absorption The first time to play hyaluronic acid, skin cells “foreign matter” will be quickly absorbed, after playing a few times, the maintenance time will be longer and longer. 3, with playing hyaluronic acid parts related to the nose, chin and other parts, because there is no activity muscle, the effect to keep relatively long, nasolabial groove, apple muscle, lips, these often because of the expression of the activities of the parts, to keep the time is relatively short. 4, hyaluronic acid brand, specification is different We usually say hyaluronic acid, in fact, can only be counted as a general term. Hyaluronic acid is also divided into large, medium and small molecules, and different diameters are used in different parts, and different diameters are used in different parts, and the duration of maintenance is also different. The absorption rate after injection is closely related to the cross-linking rate of hyaluronic acid. The cross-linking rate of hyaluronic acid contained in the human body itself is about 12%, and the closer the cross-linking rate of injected hyaluronic acid is to this value, the less likely to be absorbed. How to keep the hyaluronic acid longer? 1, don’t stay up late and don’t drink. Drinking alcohol will accelerate blood circulation, hyaluronic acid loss faster. Stay up late skin dehydration, a lot of absorption of hyaluronic acid 2, a small amount of multiple injections. If you want to play 4 hyaluronic acid on your face, it is recommended that you only play 2 for the first time, and then play the remaining 2 within 3 months. This final maintenance time, longer than a one-time all 4 injections
