Safety and Efficacy of Using LEORTEC-300 System For Hair Removal Treatment

Removal of unwanted hair is one of the most commonly sought cosmetic solutions. Traditional methods, such as shaving, depilatories, tweezing and waxing result in only temporary hair removal, and thus require extensive maintenance. Long term hair removal via electrolysis is generally unsatisfactory due to its time consuming, painful nature and the associated risk of scarring or pigmentary changes. Moreover, the efficacy of electrolysis is user dependent and is estimated to be reduction of only 15-50% of the unwanted hair3.

The more modern approach to long term hair removal involves laser and Intense Pulsed Light (IPL) treatment modalities. These technologies are based on the scientific principle of selective photothermolysis. During the treatment, the light energy is absorbed by the hair's pigment (melanin) and transmitted through the hair shaft to the follicle. Conversion of this energy into heat causes a rise in the hair temperature, leading to destruction of the follicle and disruption of the hair growth mechanism, while leaving the skin undamaged.

Both laser and light devices have been proven successful in inducing permanent hair removal, as well as delayed hair growth, while causing minimal discomfort and complications. The light devices are based on the IPL technology, which differs from laser light in various physical aspects. The main difference is that while lasers emit light at a distinct wavelength, IPL delivers a wide range of wavelengths (400 1400 nm), thus allowing greater flexibility in aspects of body area, hair color and skin type LEORTEC LTD. has developed an innovative device that integrates the two treatment modalities: Laser and Intense Pulse Light (IPL) and in addition MLS - Multi Light Source- a combination of the two modalities. The purpose of this study is to evaluate the safety and efficacy of using Leortec 300 device for hair removal treatment.
