Question, I know sun is bad for tattoos new and old but if it’s for a few minutes at a time in the sun will it effect tattoos that are a few years old? I always cover or use sunblock when it’s prolonged exposure but I work at a coffee shop and if I’m on the patio for a few minutes folding chairs will that sun exposure fade anything or am I being overly cautious? Also is a flannel a good cover for tattoos? Thanks!
