Yag and Smoothbeam Laser for Under Eye Darkness and Wrinkles?

Do Yag Laser and Smoothbeam Laser work for under eye darkness and wrinkles and nasolabial folds?

I am in my 30's and do not want to do fillers? If so, how long does this last on average? Can the lasers damage skin at all?

I have sensitive skin and I am afraid to do the treatments. I have consulted with an esthetician and she recommended 3 full face treatments.
