i have my whole leg in those stains, do u think doing the remove with a laser will be safe, and will it make it disappear? I'm 14

I've never heard of the procedure, but I'm sure it's possible. Just be sure to do a lot of research. Be careful about where you get laser procedures done. I've heard a lot of bad stories about people have laser procedures done in "spas" and being very badly burned. Make sure you go to a licensed professional, preferably one recommended by a dermatologist. And try to get a 2nd opinion. Good luck!
