In August 1997, the FDA approved the Cynosure Photogenica LPIR, a long-pulse Alexandrite laser which underwent almost two years of careful studies before its release. Results using this laser have been exceptional. These new Alexandrite systems are very quick and less painful than the previous laser hair removal systems. On average, after three to four treatments one experiences long-term relief from annoying hair growth. Laser hair removal is becoming the most convenient and economical way to remove hair from large sections of the body as well as from the face, underarms, and bikini areas.
Lasers are unbelievably expensive to own and operate.
The technology changes so rapidly that in a few short years the equipment becomes outmoded and has to be replaced. No, not always. We already have inexpensive ways to treat some of these problems. We just couldn't get the same quality of results and low complication rates with the conventional techniques. But for some conditions, the advantages of the laser are subtle.
