Yes, scars can be covered but it is a difficult and tedious process. Also, if the scar is raised there will be an indistinct area in the tattoo (where the scar is) that will be raised. Below is what is involved in covering a scar.

1. It is time consuming. Depending on the individual's skin or scar texture, a single line may require two or more passes with the needle before it takes.

2. It can be, and often is, more painful than the average tattoo. Scar tissue is very sensitive since the nerve endings are closer to the "new skin" (unless the nerve ends were destoyed when the damage occured).

3. Once set within the scar or graft tissue, black will stay. However, color will bleed or fade from the skin. There is always a slight possibility that the black may blot or run beneath the tissue, but if a very fine line is used this problem can be virtually eliminated.

4. I often recommend to my clients who wish to have their scar or graft tissue tattooed that they get a very small tattoo within the area first, as a test to determine if their skin will accept the pigment. Then, if all is well, the small tattoo can be covered or incorporated when the major artwork is applied.

5. Last, but certainly not least, it is very important that the scar and/or graft tissue be at least one year old before tattooing is attempted (the older the scar, the better). Destroyed tissue takes a long time to heal, so the older the scar, the better it will take the pigment.
