hello,i heve taken 2 q switched nd yag laser sessions on some nevi to lighten them and 6 non ablative nd yag laser sesssions on post acne scars.during the last 4 months i couldnot apply the sunscreen regularly and it was about 200 hours collectvly of indirect sunlight sxposure coming from the window as well as heavy white light at night but no direct sun exposure at all.can this lead to melanoma of the lasered neni or any malignant transformation of skin?can this pass in peace?many many thanks
