When it comes to laser cosmetic surgery, many friends know that it has a wide range of applications. Then, some friends who are afraid of pain always want to know that some painful plastic surgery will make many patients more worried. In fact, when laser cosmetic acne scars are treated, there will be some tingling and burning sensation due to the local instantaneous high temperature. However, most patients can tolerate it without anesthesia. For a few sensitive patients, local ice compress or infiltration anesthesia is needed in scar plastic surgery to reduce discomfort.
