I urge you to start with a small and inconspicous area , like the underarms.
Do a series of treatment in that area, then wait a couple years and see what the results are.
You've said it yourself. You have been seduced by advertising, hollywood movies, an exciting new technology, (and internet message boards, btw).
I hate to burst your bubble, but the seduction is driven by unscrupulous marketing combined with your own consumer niavety.
It's important to inform yourself and have realistic expectations. Even so, the nature of laser hair removal is insidious.
You may end up going through years of treatment and spend thousands of dollars. (Not to mention the pain and irritation of the procedure.) Only to be left disappointed and scarred physically and emotionally.
At least look at the FDA page explaining what "permanent" means: http://www.fda.gov/cdrh/consumer/laserfacts.html#1
Further, manufacturers may not claim that laser hair removal is either painless or permanent unless the FDA determines that there are sufficient data to demonstrate such results. Several manufacturers received FDA permission to claim, "permanent reduction," NOT "permanent removal" for their lasers. This means that although laser treatments with these devices will permanently reduce the total number of body hairs, they will not result in a permanent removal of all hair. The specific claim granted is "intended to effect stable, long-term, or permanent reduction" through selective targeting of melanin in hair follicles. Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs re-growing after a treatment regime, which may include several sessions. The number of hairs regrowing must be stable over time greater than the duration of the complete growth cycle of hair follicles, which varies from four to twelve months according to body location. Permanent hair reduction does not necessarily imply the elimination of all hairs in the treatment area.
FDA does not make comparisons between systems or how well or safely they work compared to another company's system. FDA does not recommend one laser system over another.
Lasers cleared for body hair removal are also cleared for facial hair removal.
