ProFractional Laser. Please explain what level 100 means? Is this level enough to get rid of lines/wrinkles?

I'm booked for ProFractional laser for fine lines/wrinkles. I was told laser will be set at ~100 (+maybe passing over problem areas again at lower level). They said I may only require only 1 tx. Incidentally, Chelsea Handler recently had the same tx. I look similar to her in regards to skin type/wrinkles before tx (my frown lines are worse). Would a level of 100 (+xtra passes) b enough to get rid of lines/wrinkles? What does 100 mean? I know C Handler's tx was done at level 75 w/ great results.
