What is my case's name? My options? (Photos)

Hi doctors I'm 40y old and have spots on my face. I think its from sun exposure. I've 2 questions: 1- by looking at my photo, what do you think are these, pigmentations, sun damaged spots, or something else. I don't know its name? 2- I've decided to try lesser. I went to 2 centres to know more about avaliable options. I met a doctor who told me he recommends Er:YAG to be used. In the second centre, I met a nurse who recommends using RevLite SI Laser on my face. Please help me what to do?
