Many friends of micropigmentation are most worried about what is injected into the body, if the body does not adapt to how to do? Although nowadays most of the commonly injected micropigmentation medicines are from some substances in the body itself, but it is not rigorous to say that 100% will not have allergies. What if someone is allergic to the injected medicine? Let’s learn about fillers first! First, what is a dermal filler? Dermal fillers are gel-like substances that can be used for intradermal or subcutaneous injections, and are mainly used to repair sunken deformities on the face or body surface, age-related facial depressions or static wrinkles, in addition to beautifying the five senses and adjusting the contour of the face or body. What are the types of injectable fillers? According to the source classification can be roughly divided into animal sources, human tissue sources and synthetic three categories. Although injectable fillers are strictly screened and prepared, the materials usually blend well with human tissues and allergic reactions are rare. However, when injecting certain materials that contain or have antigenic substances, or when the injected object is more sensitive to certain materials, localized allergic reactions will occur. Moreover, nowadays, the distribution channels in the market are more complicated, and there are a lot of products that flow into the plastic surgery market in an irregular way, so the phenomenon of allergic reactions also occurs. In extreme cases, severe allergic reactions may occur, such as anaphylactic shock, which can even be life-threatening. Therefore, allergy is also one of the problems in the field of cosmetic injections that should not be ignored. Third, why would someone be allergic? Injection allergy is mostly a type I allergic reaction, usually manifested as a rash. This is a more complex reaction, this allergic state can be maintained for half a year to several years, if there is no stimulation of the same antigen, and then gradually disappear. When the same antigen (such as injection materials) into the body again, will lead to smooth muscle spasm, capillary dilation, increased vascular permeability and other reactions, so that the human body rash, skin flushing, gastrointestinal discomfort and respiratory distress and other symptoms. Fourth, what will be the reaction of allergy? Allergies caused by injected materials are usually localized and relatively mild. Most of the performance for the injection area near the skin swelling, redness or rash; for severe allergy, it is manifested as shock, low blood pressure, respiratory distress, laryngeal edema, generalized urticaria and so on. But this situation is extremely rare. Fifth, once the allergy how to do? Currently for the treatment of skin allergies or stay in the conservative treatment stage, frankly speaking, for allergies, medical science has no particularly effective way, for local mild allergy, you can use symptomatic treatment: 1, oral antihistamine drugs – Mindy, Keratan; 2, localized skin rashes — can be used externally with glycerite lotion; 3, with abdominal pain, diarrhea and other gastrointestinal reactions — antispasmodic painkillers, atropine; 4, with respiratory symptoms — anticholinergic drugs, etc.. For relatively serious patients, or the acute phase of the onset of glucocorticoids can be given orally or intravenously; for serious cases need to follow the steps of anaphylaxis rescue treatment. Six, allergic people need to pay attention to what? Once an allergic reaction, and recurrent episodes, in completely get rid of allergens before the need to pay attention to diet and living habits: diet to light diet, avoid eating greasy, spicy food, away from tobacco and alcohol, avoid overheating of the environment. Some people say they can’t remember how to do? Then remember one thing, the food and environment that can make you blush, you should try to stay away from! It is also very important that you do not re-expose yourself to substances that make you allergic, for example, people who are allergic to hyaluronic acid should not try to inject it repeatedly.
