Unlike the laser method, the wavelength spectra of the light are used during the IPL treatment. Light pulses penetrate into the skin layer and are transported to the root of the hair through the hair’s melanin. The melanin converts the light energy into heat which cauterizes the root of the hair. A cauterized hair root can no longer produce hair. The IPL method is very effective in the growth phase. Depending on which part of the body is hairy, the active hair roots represent 20 -40 %. The roots of the hair are transparent during the period of dormant growth because they do not have any melanin. These are not destroyed by the flash lamp.
One must therefore wait until they are in the active growth phase again to achieve an effective result. You therefore need several treatments to remove all hair permanently.
Depending on which part of the body is being treated, one needs several treatments which must be carried out at intervals of 1 to 2 months so that every root of hair is removed permanently.
The number of treatments is therefore dependent upon the density of the hair growth and on the growth phase of the respective region of the body.
To protect the eyes, safety goggles are worn during the treatment. The IPL hand piece is then pressed lightly on the region of the body and a flash (flash-light) is triggered off. When the treating light flashes you will feel a slight prick.
