It is best not to inject hyaluronic acid during menstruation for the following three main reasons: 1. During menstruation, women’s resistance is weaker, and all kinds of bacteria and viruses are easy to attack. Although the needle used for injecting hyaluronic acid is very fine and belongs to the category of micropigmentation, the damage is very small, but bacteria and viruses may also enter the skin through the needle hole. If they invade the skin during menstruation, the patient’s resistance is low, and it is easy to cause all kinds of diseases.2. During menstruation, the patient is easy to bleed, and the bleeding caused by the injection will be small, but the blood circulation in the face is very rich, and if the bleeding can’t be stopped, the consequences will be very serious.3. During menstruation, most of the women may suffer from dysmenorrhea, and dysmenorrhea will lead to a bad appetite, and their diet will gradually become worse. After playing hyaluronic acid, you also need to enrich your diet and strengthen nutrition to accelerate tissue healing.
