I am trying to remove my tatoo myself.... what to expect?

Idk if this was a good idea or not, But I was desperate to get rid of a tatoo and I havw very little money. I followed the directions of a person who got rid of a tattoo themself. They scrubbed it with a pumice sponge for 5 minutes, and soaked it with peroxide until it was bubbling, than covered it with neosporin and a bandage. They said they waited for it to heal, and did it several more times until the tattoo was finally gone. I have so far done it once. It is in the healing process. The skin on/around it is a little raised, red and pussing. Is this normal for a healing process? How often should I use peroxide, neosporin, and bandages?
