Accutane V. Laser Hair Removal?

Just finished a 6 mnth accutane treatment. It helped with the frequency and severity of my cystic acne. However, I still have small cysts on neck as well as "regular" pimples that have stuck around for a while. One doctor has suggested ingrown hairs as a possible cause. Others say some of problem might be ingrown hairs, but mostly genetics is causing the cysts. I know both treatments are lengthy, but accutane is far cheaper for me. Do you think a 2nd course of accutane would be more effective?
