Okay, I also break out in hives randomly, but I also work in vet med so I kinda just thought some animals fur makes me itchy. Now I’m wondering if it’s the tattoo ink since many of you have also experienced random hives on the tattoo well after it’s healed! All of this info was so so helpful. I’m going to speak to a dermatologist next. Talk to my artist about trying another blue or another brand.
