You should go to a regular plastic surgery hospital for whitening injection. It is best not to consider small beauty salons. According to news reports, the situation of those who beat them in beauty salons is very serious. I think it must be a regular product that enters the body. There is a plastic surgery hospital called Meilande in the west gate of Jianye Forest Peninsula. Last time I accompanied my friend to do double eyelids, I also asked the doctor there. She said it was ok, because it is the only regular plastic surgery hospital in Zhumadian so far. I hope I can help you!
