The history of Syneron is one of innovation. With the limitations of intense pulse light (IPL) and conventional laser systems as his inspiration, master physicist, Dr. Michael Kreindel, was determined to come up with a better solution for medical aesthetics. After years of research and development, he created elos (Electro-optical Synergy), the revolutionary technology platform that powers all Syneron medical aesthetics systems. Together, he and his long-time colleague, Dr. Shimon Eckhouse, the inventor and patent holder of IPL, founded Syneron in 2000. Five product families were soon launched from this robust and promising pipeline and the stage was set for a new industry leader. Since then, Syneron has been setting new standards in safety and efficacy for a wide range of medical aesthetic procedures. The Syneron spirit of inspired innovation and commitment to excellence continues to guide the company, today, and into the future.

While lasers were invented in the mid-60s, it wasn't until the mid-70s that the technology had evolved enough to be used safely for dermatological applications. In 1991, physicist Dr. Shimon Eckhouse invented and patented intense pulsed light (IPL), a significant advancement over conventional lasers. A quantum leap occurred in the year 2000, when master physicist, Dr. Michael Kreindel, "combined" IPL technology with bi-polar radio frequency (RF) to create electro-optical synergy or elos as it is now known. This revolutionary technology platform soon set new standards in safety and efficacy for a wide range of medical aesthetic procedures.

Laser Limitations:

Single range
Single wavelength
Very few aesthetic applications
High epidermal absorption
Many treatments required
High risk of pigmentation changes and scarring

IPL Limitations:

Single range
Multiple wavelength
Limited penetration
Poor targeting and selectivity
Continual risk of epidermal pigmentation changes and scarring

The elos Advantage:

Multiple range
Multiple wavelength
Extensive applications
Excellent targeting and selectivity
Improved safety for all skin types (less optical energy compared to conventional lasers and IPLs)
Enhanced penetration for improved treatment results
Additional safety features, including Active Dermal Monitoring and RF electrode contact check

Unwanted hair growth remains a therapeutic challenge and there is a considerable need for an effective and safe treatment modality.


From an evidence-based view to summarize efficacy and adverse effects from hair removal with ruby, alexandrite, diode, and Nd:YAG lasers and intense pulsed light (IPL).


Original publications of controlled clinical trials were identified in Medline and the Cochrane Library.


A total of 9 randomized controlled (RCTs) and 21 controlled trials (CTs) were identified. The best available evidence was found for the alexandrite (three RCTs, eight CTs) and diode (three RCTs, four CTs) lasers, followed by the ruby (two RCTs, six CTs) and Nd:YAG (two RCTs, four CTs) lasers, whereas limited evidence was available for IPL sources (one RCT, one CT). Based on the present best available evidence we conclude that (i) epilation with lasers and light sources induces a partial short-term hair reduction up to 6 months postoperatively, (ii) efficacy is improved when repeated treatments are given, (iii) efficacy is superior to conventional treatments (shaving, wax epilation, electrolysis), (iv) evidence exists for a partial long-term hair removal efficacy beyond 6 months postoperatively after repetitive treatments with alexandrite and diode lasers and probably after treatment with ruby and Nd:YAG lasers, whereas evidence is lacking for long-term hair removal after IPL treatment, (v) today there is no evidence for a complete and persistent hair removal efficacy, (vi) the occurrence of postoperative side-effects is reported low for all the laser systems.


The evidence from controlled clinical trials favours the use of lasers and light sources for removal of unwanted hair. We recommend that patients are pre-operatively informed of the expected treatment outcome.
