Is excessive redness around fresh tattoos a red flag for an artist?

I recently found a tattoo artist whose work I really love, but I’ve noticed something that’s making me hesitate. In all the fresh tattoo photos they post, the surrounding skin looks extremely red and irritated. Personally, I’ve never experienced that kind of reaction with my own tattoos, so it’s making me wonder if it’s a sign of a heavy hand or something else.

That said, in the healed photos (which they also post), the tattoos seem to turn out fine. I really want to book with them, but this is making me second-guess. Is this kind of flare-up normal, or should it be a concern? Would love to hear from others who have experienced this!
