Patient: I was retaliated by someone who threw acid on my face. It was 3 degrees deep. I had a test and a skin graft. But the pigmentation is very deep. The scar is very large. Due to the contraction of the skin, the face has been stretched out of shape. Can the pigmentation be lightened now? Can I get rid of the scars? Or can those be changed through surgery? Guangzhou Red Cross Hospital Burn Plastic Surgery Department Li Ye Yang: Any surgery can only improve the scar deformity after the injury, some results are obvious, some are not so obvious. Because the photo is small, I can’t see it too clearly, so I can’t judge it exactly.
