Patient: I was born with a brown or coffee colored birthmark next to my eyes, about two square centimeters. I have never treated it, and I have always wanted to remove it, but when I asked the hospitals in Fuzhou in the past few years, the doctors said that there is no good solution for the time being. The answer is that it varies from person to person, because individuals have different sensitivity to light… My concern now is that I want to try it once, but I am afraid that I will not be treated but will be left with scars. Expert: Hello, birthmark is just a generic term for skin pigmentation disease, which can be divided into many kinds. Coffee spots can be treated by laser. After 2 to 3 times of treatment, most patients can achieve the effect of complete removal, but a certain percentage of patients may have recurrence. In addition, the skin will scab after treatment with laser for pigmented diseases such as coffee spots, and it will fall off in about 1 to 2 weeks. If care measures are taken, there will be no scar left in general, so it is still quite safe.
