Skin phototype

The purpose of skin phototypes is to determine the following:

  • the skin color
  • how the skin reacts in the sun (e.g. prone to sunburn, appearance of freckles)
  • the hair color

There are 7 phototypes: the higher the phototype, the more resistant to the sun and darker the skin is.

The physician will choose the laser hair removal machine with the suitable wavelength and fluence (energy) according to the patient’s phototype. In general, the Alexandrite machine is used for fair skin, with quite a high energy level, and the Nd Yag machine, with a low energy level, to prevent burning on dark skin, which has a particularly high concentration of melanin.

The Fitzpatrick phototype classification is shown below:
