The fact that you can get hyaluronic acid is not about whether or not you have hives, but about which cycle the hives are in. If it is acute and in the area of your procedure, you cannot inject hyaluronic acid at this time. If you have had hives, but they do not affect your injection site, this is the time to get it. Hives are commonly known as rubella lumps. It is a limited edema reaction due to the dilation of small blood vessels in the skin and mucous membranes and the increase in permeability, which usually subsides within 2 to 24 hours, but new rashes occur repeatedly. The course of the disease is prolonged for days to months. It is more common clinically. If allergic urticaria occurs, such as food, airborne dust and other factors lead to, once detached from the allergen, after the acute phase, the allergen into the body has been sensitized by the sensitized cells binding, inflammatory reaction, the symptoms will gradually subside. However, when the allergen is contacted again in the later stage, the body will induce hypersensitive reaction again and the symptoms of urticaria will appear. Therefore, this disease can not be cured by itself, patients can use antihistamines or hormone drugs in a timely manner for therapeutic intervention, and at the same time, daily life should prevent children from touching substances that can cause allergies. Hyaluronic acid originally exists in the dermal tissue of human skin in the form of gel, which is responsible for storing water and increasing the volume of the skin, so that the skin looks full, plump and elastic. As we age, hyaluronic acid is lost and loses its ability to store water. Hyaluronic acid injections for cosmetic purposes make use of this property of hyaluronic acid, supplementing synthetic hyaluronic acid into the human body to play a cosmetic role in removing wrinkles and contouring.
