Cover-up tattoos are common; people often get a design, but then change their minds (or partner) and want it covered with another image. It is also becoming more and more common, however, for people to choose branding and scarification to cover up old self-harm scars.
The technique is called ‘body reclamation’ and is meant to put those who have cut or otherwise hurt themselves back in control of their bodies and have a fresh start with no scars. Whether this is good or bad, I can’t decide.
Tattoos are also frequently chosen to cover scars, which can be a very effective method, as you can see from the pictures above.
