Welcome[mention=27176]GraceAnnne[/mention] All my tattoos, including full back have been healed with tegaderm. My routine is plastic wrap until 4 hours after tattoo, shower with hibiscrub, wrinse thoroughly, air dry 15 to 20 minutes, apply tegaderm. Leave it on for 5/6 days, remove in warm shower, gently peeling the tegaderm against the skin. Make sure to use enough overlap with tegaderm to prevent leaks. If you get a leak, remove all derm, shower routine, reapply fresh derm. I also sleep on my back and have had no issues.
