UV dots

I recently found that my hands and feet are covered in little green dots under a UV light. They are in perfect lines with the patterns in my skin. They are all about the same size and all well beneath the skin. I tried to dig one out with a needle (don’t judge me) and couldn’t get to it. Washing and scrubbing makes no difference. No family has it. No coworkers have it. No friends have it. I found two other Reddit posts showing the same issue and got no answers. Hopefully I can get somewhere here.
