Long-term hair removal based on light energy
Silk’n Glide™ is a light-based electrical device for long-term hair removal
developed for home use.
The process of laser and light-based hair removal is well tested and has been
proven as a safe and effective way to reduce hair growth in the long term.
How can light remove hair?
Light-based hair removal uses selective photothermolysis in which optical
energy is used to prevent hair growth.
In order to achieve this thermal effect, the hair shaft needs to selectively
absorb light energy and transform it into heat. This selectivity is achieved
when optical energy that is delivered to the tissue is mostly absorbed by the
pigment in the hair shaft, while the skin and surrounding tissue remain cool.
Melanin is the pigment in the hair shaft that is responsible for absorbing the
light, which generates the heat that eventually prevents hair growth. The more
melanin present in the hair (i.e., the darker the hair color), the more light that
can be absorbed and the more effectively the light can eliminate the hair.
For this reason the device is only suitable for white, blond or otherwise light-
colored hair to a certain extent.
