How do you fill the dents in your eyes? How can we be safe?

In terms of security, three types of dented filling material are:The first is lump-size fat, such as fat in eye bags, fat on cheeks, which do not cause embolism when filled with eye nests. The survival rate is high.The second is fat taken from the body and injected with a blunt needle. This method does not generally cause embolism, as long as the doctor does not take the needle.The third is a relatively high daily use of urea, glue protein. When filling a dent in an eye, it is also necessary to use a blunt needle, which is equally impervious, with attention to the level and angle of the needle.
