Tretinoin and ND yag 1064 laser treatment?

My dermatologist recommended that I get 5 weeks of treatment done with the 1064 ND yag laser. My aesthetician wants me to use tretinoin every night besides the night of the treatment, as it will help the zits come to the surface and be treated by the laser. Their claim is that this laser is a be all end all cure for acne, so I'm concerned why they'd want me to use tretinoin as well. Is this safe? And also, would the combo this combo be as effective as the dermatologist and aesthetician claim?
