IPL is not a laser; it is a xenon flash lamp. In contrast to hair removal lasers, IPL devices were first developed for the purpose of photorejuvenation. Wrongly marketed as faster and cheaper, IPL does involve shorter sessions since a thicker tip is used. However, it requires more total sessions to achieve a genuinely permanent result: an average of 10 to 12 with IPL versus 5 to 6 with a laser. Consequently, unlike lasers, IPL is an option only for light skin and dark hair.
A diode laser hair removal, which targets melanin and has an 810 nm (nanometre) wavelength, works only on brown and black hair. Some are equipped with a sapphire tip integrated on the handpiece that cools the skin at 4° C. Direct contact of the tip with the skin increases the efficacy of laser hair removal by 40%.Studies show an average loss of hair by 46% after only two treatments of laser hair removal with diode as those used by epiderma.
The industry experts and medical practitioners consider the laser diode as THE standard in laser hair removal because it is the most effective, most efficient and safest on the market.
Does not concentrate on just one target because it uses a range of wavelengths so light goes in various directions.
Therefore, the results are not as successful as with the diode laser hair removal and number of treatments required to achieve definitive results is often much higher than laser hair removal diode.
IPL device is generally cheaper to buy a laser diode, the selling price to the consumer is lower, but patients treated with an IPL tend to have less desirable results.
