WHICH aftercare regimen should I use for my foot tattoo?

Don't cover it unless you are going to be out in the sun. If you cover it, the scabs will get pulled off with your sock and you will lose colour. Keep it open and let it dry out, except for the moisture you get by putting your ointment on it. Also, don't get it too wet in the shower. It's fine to let water wash over it, but do not submerge it. Never pick the scabs off either. If you are going to be out in the sun, I would wear a very very lose cotton sock over it, but no shoe. Hope this helps you out! :)
