Light Based Hair Removal
The process of laser and light-based hair removal is well known and established. It has been proven in clinical use around the world for over 15 years as a safe and effective way to achieve permanent hair removal.
Light-based hair removal is 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, permanent hair removal is achieved.
Home Pulsed Light(HPL)
Silkn Flash & Go is a personal combined-energy based device for long-term hair removal. The Silkn Flash & Go 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 permanent epilation with low level of optical energy without the need to cool the skin.
Hair Growth Cycle
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, are both resting phases.
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, and for some individuals it may take 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 laser or light hair removal treatment. However hairs in the growing Anagen phase will respond. It is therefore important to understand that it may take a full hair growth cycle to achieve complete results when doing any energy based hair removal.
It is important to understand more about HPL and how it works on the skin. As with any light-based or laser hair removal device, results are not immediate and may take a few treatments. Hair may appear to be growing back after a treatment, but typically after two weeks many of these hairs will simply fall out. In addition, hairs grow in three different stages and only hairs in an active growth stage will be affected by a Silkn Flash & Go treatment. This is one of the main reasons that multiple treatments are required to achieve the desired result for any energy based treatment (whether at home or even in a clinic!)
Most people start to see noticeable results after four treatments, and great results after six treatments. Maintenance treatment are common after eight treatments to treat stray hairs that may have been in Telogen or Catagen phase or to treat patches of hairs that were missed in initial treatment.
In a two-year multi-center clinical study HPL Technology has been proven safe and effective for the treatment of facial hair. Silkn Flash & Go can be used for treating facial hair from the cheek line downwards. Extra caution should be made to avoid the eyes.
Sun Protection Is important
Extra care should be taken to avoid sun exposure before and after treatments with Silkn Flash & Go. Acceptable means of sun protection are covering garments or sunscreen (SPF higher than 50) used continuously for 3 weeks before and after treatment.
Do not use Silkn Flash & Go on naturally dark skin complexion
Silkn Flash & Go removes unwanted hair by selectively addressing hair pigment. Varied quantities of pigment also exist in the surrounding tissue of skin. The quantity of pigment in a particular persons skin, or your skin complexion, determines the degree of risk they are exposed to using Silkn Flash & Go hair removal device.
Consequently treating dark skin with Silkn Flash & Go and any other hair removal device, can result in adverse effects such as burns, blisters, and skin color changes (pigmentation changes.)
To address this issue, a unique SKIN COLOR SENSOR is embedded in the Silkn Flash & Go to measure the treated skin complexion at the beginning of each session and occasionally during the session. The SKIN COLOR SENSOR ensures that pulses will only be emitted on suitable skin tones taking the guess work out of treatment.
