回复：好妹妹，谢谢了。有没有痕迹？休息多久呢？

I did it once. It took 7 days for all the scabs to fail off. But the result is very very good. There is no scar. No hyper or hypo pigmentation. I am planning for a second smaller treatment, since there are about 10% freckles left (they are lightened, but not completely removed).

You have to find a good doctor. Make sure that the doctor knows Asian skin well. I found a Korean doctor.
