How many fractional laser treatments should i get?

Ideally, one: Skin resurfacing with fractionated lasers attempts to balance between treating enough surface area to rejuvenate your skin and leaving untreated skin intact to hasten recovery. This requires fine tuning the treatment density and intensity to meet your goals. It is possible to spread a single treatment over several sessions, but this should be discussed ahead of time with your provider.

Ablative or not?: Non ablative lasers work by heating the deeper tissue to get new collagen formation. They have less down time, but require more treatments (typically up to 5). Ablative lasers both ablate the surface and heat the deeper tissues with more initial down time and recovery, but require less treatments (one or two). Patients lifestyle tends to dictate which recovery they want to tolerate.
