Flat birthmarks are fine. I was told you can’t tattoo over raised ones, although I suspect this might be more about detecting skin cancer than anything else.

Yea my tattoo artist told me that some skin surfaces can't be tattooed but mine was just a weird looking pattern. Could be about skin cancer or macrophages that feed on the ink.

I've seen a video of one person doing birth mark tattoos with pigment that matches their skin color to effectively disappear them. I'm sure if you got a tan or something they would look like a color negative of the originals but for casual appearance that might be something worth looking into.

Definitely an option. Depending on where you live, it might be possible to maintain the same skin color year round.

I got it covered but I thought about getting a more elaborate design at some point. I wanted something minimalist as my first tattoo to see how it does. Now that I like tattoos I'm gonna experiment more in the future.

It's definitely doable and could be a boost in confidence for some people, like it was for me.
