1.Which hyaluronic acid is suitable for chin and nose? Which ones are suitable for tear troughs and lines? Hyaluronic acid is divided into large, medium and small molecules. Generally speaking, large and medium molecules are suitable for large areas (e.g. forehead, couple’s palace, apple muscle, nose, chin), while small areas (e.g. tear trough, decree lines, deep wrinkles, lips) are suitable for medium and small molecules for filling, but if the physician is skilled and uses it properly, he can still compound different molecules of hyaluronic acid for aesthetic creation, using large and medium molecules as the foundation and small molecules for modification to make the overall It feels more natural, round and Q-tip. 2.Why do some people have bruises after hyaluronic acid injection and some do not? There are two major reasons for bruising: personal body type and physician’s experience. Experienced physicians are less likely to cause bruising due to their rich experience in administering and the short time of application and evaluation. Other than that, it is of course related to the individual’s body type (those with sensitive subcutaneous microvessels) and lifestyle. What can consumers do to prevent bruising? (1) Stop taking aspirin and blood-stasis-activating drugs two weeks before the injection to reduce the triggers that may cause bleeding, otherwise the incidence of bruising will increase. (2) Secondly, customers who suffer from coagulation disorders such as hemophilia and thrombocytopenia will have a much higher chance of bruising, and some of them are not even suitable for hyaluronic acid injection. 3. Is it true that hyaluronic acid will cause double chin after more chin injections? In general, hyaluronic acid injections into the chin will not cause a double chin if the physician’s technique is pure and the needle is placed in the right place. This has a lot to do with the experience of the physician, and experienced doctors generally use the “multi-point method” to perform chin micro-injections. Through multi-layered and compound building program, the chin will be more natural and shaped. 4.What is the problem of the redness of the injection site after hyaluronic acid injection? The redness and swelling of the skin are related to the thickness of the skin, excessive dosage and skin infection. The first two factors depend on the designer’s dosage assessment and the physician’s basic assessment of the thickness of the customer’s skin. As for the latter, infection varies from person to person. Therefore, a post-operative visit is very important! As long as the experienced physician can give the best improvement plan. 5.Can I have hyaluronic acid during my physiological period? It is recommended to avoid the physiological period. Because the hormones and metabolism are different during the physiological period, it is easy to cause bleeding and redness during the procedure. Therefore, it is generally recommended to avoid the physiological period. 6.Can I pinch myself if I am not satisfied with the shape after the injection? Generally, after the filler injection program, the physician will first give the shape. After shaping, professional nursing and consulting staff will give post-operative advice and also guide the correct home shaping technique. As long as you do a complete post-operative care reminder, you can do a little shaping and fine-tuning at home. However, in general, regular medical aesthetic institutions will let the consultant conduct post-operative consultation services again. In general, it is recommended not to do too much shaping without authorization. Because hyaluronic acid has not yet been shaped, it is easy to affect the beauty of the physician after shaping. It is still recommended to let the professional consultant make observations during the post-operative consultation, and then see if you want to reshape or make up for it. 7.After hyaluronic acid injection, is it really possible to maintain longer time with batch replenishment like 1 month, 3 months and 6 months? Hyaluronic acid generally lasts for 8-12 months (depending on the individual’s body type). Generally, we will arrange a return visit within 7 days after the injection, and we will mainly apply hyaluronic acid to the deficient part for 1-3 months, and then we can reapply the injected part again after 6 months. The effect can be maintained for a long time and is also more natural if you continue to follow this schedule for microfilling. 8.What is the reason why some people feel that the bridge of the nose has become wider after injection? (1) The injected dosage form is not suitable for injecting the root of the nose. (2) The physician’s technique, aesthetics and shaping ability are insufficient. (3) The dosage of injection is too much.
