Could be poor application of the tattoo or after care. Sounds like they over worked your skin a bit, which happends a lot with solid black fills. Would really help if you post photos of the tattoo…. In regards to the ink, who makes the ink they used? I don’t think Tribal Ink is a ink company, say like: Eternal, Intenze, Starbrite, Fusion,etc… I’ve never heard of it or used it.
What are you using/doing for after care? I’ve had some clients tell me some crazy ass after care instructions other tattooers have given them with their past tattoos. If a tattoo is too dry during healing, it will over scab, which is not good as it will heal deeper in the skin and take longer and could heal a bit patchy,etc… One reason why solid black tattoos are a waste of time to do. You don’t want to over moisturize a tattoo either….
Anyway, becareful with the tattoo for the rest of the healing and hope it works out for you!
