Needle-free atomization technique for wrinkle removal, which involves using an insulin pneumatic needle to inject products such as botulinum toxin, hyaluronic acid or growth factors into the skin using a certain amount of air pressure. It is less safe and higher risk compared to needle injection, but the same as needle injection is that both methods will break the skin, and because the diffusion injection method can not control the level and scope of drug diffusion, it is actually a less precise way of subcutaneous injection, and microplastic injection is precisely the most need for fine control, it is mostly a gimmick implemented by studios and beauty salons, most regular plastic surgery hospitals at present The main hazards of this technology are as follows: 1, the effect of needle-free atomization to wrinkle is short-lived, more than 1-2 months, repeated injections are needed, and the technology may lead to local allergies, swelling, infection and other symptoms. 2, some patients may also experience aggravation of dark circles, wrinkles, scars and bruises after doing needleless atomization wrinkle removal. To sum up, needle-free atomization wrinkle removal operation should be carried out in regular and qualified hospitals or institutions, and regular hospitals currently use wrinkle removal needles for local wrinkle removal, so do not blindly pursue new technology to avoid damage to health.
