1. Having scar surgery does not mean the scar disappears. 2. It makes messy scars look neat. 3. The surgical result was disappointing, but the location and the scar were difficult, and the doctor explained this in detail in advance, and I agreed to the surgery. 4. I am thinking about trying laser treatment at another dermatology clinic.
Even so, it is better than not doing anything, so I do recommend it for now... Of course, keep in mind that scar surgery will absolutely never give 100% satisfaction.
