Hello, I also work in a plastic surgery hospital. I haven't heard that we charge a deposit for cosmetic surgery in our hospital. In recent years, hospitals and customers are most afraid of medical accidents, so generally speaking, there is no need to worry too much about safety, but small beauty salons don't know. Generally, it is no good asking you to pay in advance, so there is no bargaining chip with him in the future. Be careful of being pitted.
