Hello! According to your description, once a scar is formed, it is difficult to remove it with drugs. You have a scar constitution. Generally speaking, for scar physique, large and small operations will eventually produce new scars, so I suggest you go to a regular scar hospital for non-surgical treatment. Suggestion: Pay attention to a light diet in daily life, avoid spicy and greasy sauces, eat less foods with more pigments, eat more fruits and vegetables, and drink more water to supplement vitamins. I hope the answer will help you.
