Tattoos can take 4-6 weeks to heal, longer if they went in rough. Give it a couple of months.

Hey guys. I recently got a tiger tatt on my arm around 12 days ago. My aftercare consisted of washing and applying aquafor on days 1-7 then non scented lotion from day 7-12. The tattoo still has hard scabs and becomes very dry 15 mins after applying lotion. I also see some of the like work is turning into a blueish/greyish color. Should i be worried? 

Don’t mess with a good tattoo. Whoever told you that you could “remove” parts of a tattoo was being extremely optimistic. You have a better chance of ruining it than improving it. Leave dates of birth and script to the tourists.
