Facial scars are a wordless pain for many people, which are often the result of deep scars left by trauma such as burns, scalds, and surgery. Depending on the aesthetic plastic angle, we often divide facial scars into two categories: the first category is facial scars with functional disorders, where patients suffer from conditions such as eyelid ectropion, crooked corners of the mouth and small mouth deformities; the second category is large scars that do not have functional disorders but hinder the aesthetic appearance of the face, which may be proliferative or flat, with the latter being the majority. Cosmetic experts remind all beauty lovers that to remove facial scars safely and efficiently, they must go to regular beauty hospitals.
