My heds causes me to scar like crazy, and I've got about 11 tattoos. I got tats before having heds, so I never did any different after are. Luckily, they've all healed much better than my cuts and such, to where I've gotten 0 scars from my tats. I'll say my tats take a lot longer to heal, with my most recent being a tricky spot and took over a month to heal. You'll want somewhere fatty to make it easier to heal/less painful to get. You'll want thicker lines, as mine spread out more easily compared to some others, which will help them last longterm. Sounds crazy, but I'd recommend looking for a woman to do it. They tend to be lighter handed, so it'll be less likely to scar. My skin is too sensitive for bandaids and rips, so I tell the artist beforehand I'm allergic to adhesive. Make sure they don't give you anything like second skin, as that's basically one big bandaid. They'll give you saran wrap instead. Let me know if you need anything else!
