Can you tattoo over old tattoos?

Answer 1

Yes they have cover ups but make sure you pick something that you are willing to live with because they are more solid and will be harder to cover up if you would be able to at all without continually getting larger and larger.

Yes as long as the color of the new tattoo is darker than the old one. I've had it done.

Doesn't have to necessarily be darker as colours in the darker end of the colour spectrum can work incredibly well, blues, greens and purples. You can use white highlights as well as white can work well over even the darkest blacks (Lucky Diamond Rich is having white tattoo designs over the black)

Some tattoos can be completely "covered" by a professional tattoo artist who specializes in "cover-ups". Letting the artist guide you as to what can be done is the best way to go with this, and ideally you will be looking for a design that has a lot of detail in it: Japanese lends itself to this very well, as does mandalas, a tattoo can be covered with this kind of design, using colour, along with white ink. White ink may have to be done a couple of times however, to make sure it has covered what was there.
