Anyone had a “blue light treatment” on their face to remove pre-ca?

I had a blue light treatment on 11/15/24. It is most unpleasant and my age spots are darker and more spots gave been added. I thought this would get rid of them! I have not begun to peel yet, though, so I am hopeful. This is has been extremely painful. My dermatologist wants me to go this twice. I’m considering saying “no, thank you. Once is enough!”
