i got a tattoo of a star on my inner wrist exactly a week ago today. i would say it has formed a fairly thick scab since then and has hardly given me any itchiness, however i’ve still been applying fragrance free lotion for the past 2/3 days. today, i think something probably scratched off a part of the scab during work OR can it really be the scab falling off? does it happen after 7 days? and IF it was accidentally scratched off and not falling off on its own, what damage does it do to the tattoo?
