There are a few things to consider before starting a diode laser treatment. Already 4 weeks before the planned first treatment appointment you should refrain from waxing, epilation or sugaring. The reason for this is that with these mechanical procedures the hair is torn out together with the root. However, the light needs a conductor to reach the hair root which is only possible via hair.
However, shaving is recommended, because then the skin can calm down before the appointment. Shaving is different in that the hair is only cut off superficially, so the lower part remains in the skin and can transmit the light of the laser.
Pigmentary changes in the skin and tattoos are, however, omitted or covered, as these areas could react to the heat. Therefore, these areas must be omitted during treatment.
