Hair removal treatment

Hair removal Efficacy

The first use of a specific IPL hair removal system developed for hair removal is reported in the literature in 1997. Hair count reduction was found to be ~60%(12 weeks), 75%(1 year), 60%(2 year). Various treatment protocols have been studied.

It is important to note that these studies utilized a variety of IPL devices on various skin areas, and used patients with varying hair and skin types. Thus the results are not directly comparable. In evaluating these results it is also important to remember that even a reduction of 75% indicates that 25% of the hair regrew after treatment. Permanent hair removal in these studies, as defined by the FDA, means the "long-term, stable reduction in the number of hairs regrowing after a treatment regime". 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 by body location. No treatment to date has shown the ability to permanently eliminate all hair growth, however many patients experience satisfaction with a significant and permanent reduction.

A 2006 article in the journal "Lasers in Medical Science" compared IPL and both alexandrite and diode lasers. The review found no statistical difference in effectiveness, but a higher incidence of side effects with diode laser treatment. Hair reduction after 6 months was reported as 68.75% for alexandrite lasers, 71.71% for diode lasers, and 66.96% for IPL. Side effects were reported as 9.5% for alexandrite lasers, 28.9% for diode lasers, and 15.3% for IPL hair removal. All side effects were found to be temporary and even pigmentation changes returned to normal within 6 months.
