functionality
- Preparation : Before treatment, it is recommended to cleanse the skin and avoid sun exposure, as the laser relies on the contrast between skin and hair color. The hair should be shaved shortly before treatment so that the laser can target the hair follicle directly, without the hair length absorbing the energy.
- Procedure : During the treatment, a laser device is placed on the skin. Depending on the device type and treatment area, a cooling device or cooling gel may be used to protect the skin and make the treatment more comfortable. The laser emits precisely controlled pulses of light, which are absorbed by the melanin in the hair and converted into heat, damaging the hair follicle.

- Multiple sessions required : For optimal results, several treatment sessions are usually necessary, as hairs in different growth phases need to be treated.
