Clinical Results
The Home Pulsed Light technology of the Silk’n™ has been the subject of multiple, on-going clinical studies by physicians around the world. Many studies have been published in top level, peer-reviewed medical journals.

"After supporting the development of leading professional IPL and laser systems for hair removal, and using them in my clinic for many years, I introduced Silk'n to my patients.
After 4 to 6 treatments with the Silk'n device they were extremely satisfied to see dramatic hair reduction."

The process of light-based hair removal has been proven in clinical trials as a safe and effective way to achieve long-term hair removal.
Light-based hair removalis based on the theory of selective photothermolysis in which optical energy is used to disable hair growth. In order to achieve such thermal effect, the hair shaft needs to selectively absorb light energy and transform it into heat. This selectivity is achieved when high optical energy that is delivered to the tissue is mostly absorbed by hair shaft pigment, while the epidermis and the surrounding tissue is actively cooled (by a cooling mechanism). Melanin is the pigment in the hair shaft that is responsible for the absorption of the light, which generates the heat that eventually disables hair growth. When hair growth is disabled, long-term hair removal is achieved.
Silk'n™ is a personal combined-energy based device for long-term hair removal. The Silk'n is based on Home Pulsed Light™ (HPL) technology which is a proprietary and patented technology of Home Skinovations Ltd. Epilation with Home Skinovations' proprietary HPL technology is enhanced by a unique acoustic effect that improves the normal process of photoepilation, enabling long term epilation with low level of optical energy without the need to cool the skin.

Before HPL™ Treatment:
Healthy hair follicles with normal hair growth |
|
 During HPL™ Pulse for hair removal:
Light energy combined with the acoustic effect is selectively absorbed in the hair shaft and disables hair growth
|
|
 Immediately After HPL™ Pulse:
Energy is absorbed by the hair follicles while the surrounding tissue remains at normal temperature and hair removal is achieved.

Every hair in our body goes through the three phases of the hair growth cycle: Anagen, Catagen and Telogen. These phases have an important impact on how the process of light-based hair removal works.Anagen is the hair growth phase while Catagen and Telogen, both are resting phases. |

Anagen phase Catagen phase Telogen phase |

The time it takes to complete a full hair growth cycle varies from person to person and the location of the hair on the body, but is typically 18-24 months. At any given moment the majority of the hair follicles in any skin area are in the resting stages. These resting hairs cannot be effected by Silk’n. However hairs in the growing Anagen phase will respond to Silk’n™ treatments. It is important to understand that it may take a full hair growth cycle to realize complete results when doing combined-energy based hair removal with Silk’n™.

 As a leading investigator in the development of IPL systems for hair removal, I was impressed by the marked clinical results that were achieved with Silk'n. Patients who were previously treated with professional hair removal systems used in my
clinic had a chance to use Silk'n in clinical trials. They reported that self-treatment was easy, relatively painless, and resulted in noticeable hair reduction after each treatment."
