What Is A Tattoo?

To understand any method of tattoo removal you first need to understand what a tattoo really is. Yes it is a bit of ink in the skin but there is more to it than that.

A tattoo is a pigment that is under the epidermis (in the dermis). As the needles goes in and out of the skin it deposits ink in this section on the skin. Sometimes the ink doesn't make it all the way through and this ink peels off as the skin sheds (if you've had a tattoo you know about the peeling procedure) leaving just the ink in the dermis.

The body thinks that the pigment is a foreign substance (which it is) and releases white blood cells to get rid of it, however due to the large size of the pigment it cannot be removed from the body via the immune system.

This is what makes a tattoo permanent and to understand how any of the removal methods work you'll have to understand this.
