I'm not the right guy to ask about laser. I have never performed laser and the only clients I see are those that had "failed laser." So, my opinions would be, necessarily, one-sided AND not correct.
I only know what a proficient electrologist could deliver ... but, if you go with electrolysis, get the therapist to give you REAL answers and specific outcomes.
With whatever modality you decide ... take lots of "before" photos. Get the person to give you some reasonable idea of the time and MONEY you are going to spend on the project. AND THEN, if they don't deliver ... what then? Do you spend 2X 3X 4X the money ... or, do you get your money BACK!
I prefer real answers ... an attempt to give you "final results," and I especially like the "I get my money back if it fails."
Instead of thinking about this as some sort of "mythical experience" think about this like getting a paint-job on your car ... shop around and get the best estimates and the best "painter." Go rational ... not "emotional."
