No plastic surgery hospital is needed. Any surgical hospital can do it. I have seen a similar operation, that is, cutting off the tattooed skin, and then sewing up the surrounding skin, a minor operation. It doesn't hurt at all if you use anesthetic.

There will be a small scar, which is still not obvious if the stitches are well maintained. This operation is not recommended if you have scar skin. Otherwise, the scar will bulge. Obviously. However, you have been laser washed twice. If there is no scar, it means that you are not scar skin.
