Yes it's bad for your body and because of the image that you'll give for yourself.
I dont understand why someone would do this to his body, + it's not beautiful. (the same thing for permanent tattoos)

I agree w/ Viper.

it's fine if you like it

i think it's not good :for me i don't see that makes person beautiful ;on the contrary ,i find theese people agressive and im not able to see their faces
