i also had my 3 墨 removed by doctor last month. One on each side of face and one close to my eye. One is quite big and raised.
It done by laser. Very safe. No pain, now the skin just little bit red.
Doctor said it will become invisible after about 2 months.
My doctor also done it by Laser. As I know for the small one (芝麻size) is $1,000 for 3 pcs & minimum charges is $1,000. The others size or many 墨, u can consult by Doctor first.
