Thanks to the frequent impulses and thus lower energy, the risk of burns can be reduced.
With every treatment the goal is to denature the proteins. These are located in the hair root and are
essential for the growth of any hair. Denaturation takes place by the heat applied during a treatment.
When the proteins are denatured, the hair root is no longer supplied with nutrients and thus precipitates
after some time. For the same reason, a regeneration of the hair is prevented, which is the basic principle
of many laser methods.
The wavelength of the diode laser with 808 nm is optimal for the energy transfer, to the endogenous dye
melanin in the hair suitable. This dye converts the light into heat. During treatment with the diode laser,
the handpiece sends controlled light pulses above the desired location. There, the light is absorbed by
the melanin, in the hair root.
MODE OF ACTION
Due to the absorbed light the temperature in the hair follicle is raised and the proteins denature. After a
destruction of the proteins no nutrients can get into the hair root anymore, which leads the hair to falling out.
Without the supply of nutrients, no further hair can regrow.
During a treatment with the diode laser 808, the heat can only penetrate the skin layer containing hair papillae.
Due to the constant wavelength of the laser, the other skin layers are unaffected. Likewise, surrounding tissue
and blood is not affected. Because the dye haemoglobin contained in the blood reacts only to a different wavelength.
Important for the treatment is that there is an active connection between the hair and the hair root. Because
only in this growth phase, the light can reach directly to the hair root. For this reason, it takes several sessions
to achieve a successful treatment of permanent hair removal.
BEFORE THE LASER TREATMENT
Before a treatment with the diode laser, waxing or epilating the hair must be absolutely avoided. With such
hair removal methods, the hair is removed with its hair root and therefore are not treatable anymore.
When shaving the hair there is not such a problem since the hair is cut off above the skin surface. Here the
essential connection to the hair root is still intact. Only this way light beams can get to the hair root and a
successful permanent hair removal can be achieved. If this connection is interrupted, is takes about 4 weeks
for the hair to reach its growth phase again and is treatable.
Pigment or moles are covered before each treatment or get completely omitted. The reason for this is that
there is a high level of melanin in the stains.
