I'm telling you, it's best not to take the risk. In a short period of time, micro-plastic surgery has little risk and will not affect normal life. But this kind of micro-shaping often can't be corrected once. After an operation, there are often many maintenance operations, large and small. The operation itself is not very expensive, but the later maintenance ... is really hard to say.
And the failure of the operation will lead to wound infection, wind failure and so on.
If you think the lip line is not good enough, in fact, makeup can make up for this defect. If you go to Baidu to find out how to mend your mouth, there is really no need to make fun of your face.
