A: After years of clinical trials, hyaluronic acid injection is a very safe and simple non-surgical plastic surgery method. Because the method of rhinoplasty with hyaluronic acid is very simple, many people think that playing hyaluronic acid in beauty salons is not affordable, so they want to play hyaluronic acid at home to save time and money. In fact, the specific application of hyaluronic acid injection is relatively simple, but it also requires certain skills. It is difficult for an unfamiliar novice to obtain the ideal injection effect. Professor Ren Jianxin from Tongji suggested that it is best not to inject hyaluronic acid easily. Hyaluronic acid is a kind of high molecular aminopolysaccharide, which exists in human tissues. Hyaluronic acid is fused and expanded with the original hyaluronic acid in the body by injection, and the skin can swell without surgery. Suitable for beauty seekers with slightly lower nasal roots. This is a quick and seamless beauty method. There are many tips for rhinoplasty with hyaluronic acid injection, mainly in the form of points, springs, tiles and fans. The interactive application of these styles of play can achieve the most perfect rhinoplasty effect. Professor Ren Jianxin of Tongji reminded that hyaluronic acid is a dermal filler, and improper injection of hyaluronic acid will easily lead to skin necrosis. The needle used when injecting hyaluronic acid is also very particular. There are two kinds of sharp needles and blunt needles. Sharp needles can be injected directly through the skin, mostly for injection of superficial epidermis, and blunt needles are mostly used for injection of deep epidermis. Different parts should be injected with different needles, so it is difficult to judge if you inject yourself. If you want to get the best injection effect of hyaluronic acid, you must not give it yourself easily. It is best to choose a regular institution for injection, so that the good effect achieved is more secure. Plastic surgery should be cautious and avoid blind surgery.
