Remember to do your research and ask the questions before selecting the physician to perform your next laser treatment.  This site is a big proponent of using a physician to perform your laser procedure as they are more qualified and better trained to understand the associated risks of the various laser procedures.  In rare cases you may find a very well trained Physician Assistant or Nurse Practitioner to perform your procedure but you should only decide to do this after seeing before and afters and speaking with former patients who had the same procedure.  You are making an investment into the most important item you possess, your BODY, this is why you need to spend the time necessary to ensure a wise investment.  Although, risks are minimal and side effects rare, they can still happen and you need to minimize this risk by having your procedure performed by a well-trained provider who will stand behind his/her work.
