Normal Fraxel Repair Settings for Acne Scarring?

What Fraxel Repair setting ranges are normally be used for acne scarring? I'm 39 years old and must return to work no later than 10 days after. Although my physician (board-certified dermatologist) is highly experienced with lasers in general, I'm a test patient for Fraxel Repair. I have some cystic acne scars (not too deep) except for my entire jaw area which is quite has very uneven texture. I am still breaking out, mostly along the jawline (photo). The doctor said it'll be done aggressively all over except in nose area, but can't really tell me what to expect. Is 10 days realistic for an aggressive treatment? Thanks.
