E45 or savalon are your best bets. thi will stop it from getting infeected and limit scabing duration.
apply a light coat of cream to the tattoo and leeve to settle into he skin. avoid soaking your tattoo e.g. haveing a bath untill it is heald fully (3 weeks max). when drying the area after a shower etc lightly dab it ,do not wipe.
DO NOT PIC IT. this includes scratching.
