try https://saniderm.com/ I use the https://saniderm.com/product/personal-size-10-2-in-x-2-yd-roll/ I have been using it for several years now on many tattoos, and this shit works great ! put it on 24 hours after the tattoo and leave it on for 4 or 5 days, take it off and it's healed. you can sleep, wear any clothing, shower, whatever with it on.
the first 24 hrs after the tattoo I use cocoa butter and saran wrap,wash it with anti-microbial soap every few hours, wash it once more, dry it with clean paper towels, apply the saniderm on clean dry skin. BAM
be sure and carefully shave the area to be tattooed and for several inches around it so the saniderm sticks good.
that's my method, I have been getting tattooed for many many years and have tried EVERYTHING over the years,and IMO this is the best way.
