Big hospitals have double eyelids, but if you do general catgut embedding, you don't need to go to big hospitals. I had sex with some friends in the hair salon. I've been doing it for 2 months now, and it's still a little swollen, but my friends who work with me have recovered better than me, which is related to individual differences. In addition, some friends have worked in You Na Beauty Salon and Yonghua North Road Beauty Salon, both of which are good. Now the technology is quite mature, and many places have been consulted. I hope the information provided will be helpful to you.
