First of all, we must determine whether we are scarred or not. If so, then you can't get a tattoo. People with scar constitution, as long as they have physical trauma, will leave scars like acne. It will be even uglier then.
If you weren't scarred. You can go to the scar treatment place to see if it can be cured. If it is cured, there is no need to cover it with tattoos.
I suggest you go to "Xinyi Quscar" and "Baidu". You can watch it once. That's good. You can also ask about yourself by phone.
