Risks and benefits of Pulsed Dye Laser (Photo)

My local dermatologist (who also specializes in cosmetic dermatology) has recommended that I do a few sessions of the Pulsed Dye Laser to address the red spots on my face from acne that are left before I purse the Infini for the indented scars on my face. I had decided not to do laser for my indented scars due to the risks and reviews I've read online, plus it does not address the indents. What are the risks of the PDL? Change of skin texture or premature aging down the road? Is it safe?
