In the old method of tattooing, a local anesthetic is used on the tattooed region, after which salt water solution is applied. An abrading instrument is used to remove the tattoo and dressing is applied in case of any bleeding.
The method is very risky, as there are chances of getting infection, and in case the wound is deep, it can worsen the situation.
I would suggest you to only go for the latest laser tattoo removal methods which are safe, fast and effective as compared to others. More Info>>
