How can I avoid developing more scabs?
To avoid scabs you must keep your tattoo moist. I prefer to coat my tattoos with a thin layer of Bacitracin for at least a week. If the tattoo doesn't dry out, it won't scab.
Is ink going to come out when they fall off?
As long as you don't remove the scabs prematurely your tattoo ink should stay intact. It's when tattoo scabs get bumped or picked off that pigment comes out. If you allow the scabs to fall off on their own you shouldn't have a problem.
