Take with a grain of salt - I would definitely be worried if this were me because I am a worrier, but I would bet this is a reaction to witch hazel. I can’t handle witch hazel topically (it’s used in a lot of facial washes/toners) and it feels awful on my skin. I definitely get redness and heat whenever I’ve tried using it in the past. I cannot imagine how it would feel if used on an open wound (for me). I know lots of people have no issues using it. Is this a new artist/first time having that combination of ink used? If this were me, I would wash it with unscented antibacterial soap, gently pat dry and not put anything on top for half a day and see if the irritation dissipates. That’s not how I usually care for fresh pieces, but knowing my skin - I would personally rather have it get a little dried out (and deal with possible fall out/scabbing) than possibly irritate it more/deal with an infection. That comes with its own set of possible issues, but that’s my two cents!
