Actually, it's as simple as injecting an epipen. So you can carry Dust filled syringes to recharge the tattoos. But depending on who you want to have tattoos, not everyone likes needles and will feel comfortable doing that. However in battle, you need to be able to deliver the injection quick.

Also I never said you had to hold Dust powder with your bare hands. This is just an idea so I am not sure if it's a proper method.
