You should consider these factors:
Your tattoo removal site is at risk for infection and there's a slight chance you'll have a permanent scar.
It’s unlikely that your tattoo will be completely removed.
The skin that is treated may end up paler than the skin surrounding it. It's also possible the affected skin ends up darker than the rest of your skin.
Cosmetic tattoos like lip liner, eyeliner, and eyebrows may get darker after treatment. They do tend to fade with more sessions.
