Laser hair removal

Diolaze – the latest and fastest laser technology now available at Diacor

During laser treatment, diode laser light travels through the skin and strikes the hair follicles, which contain melanin. The diode laser energy is absorbed by the melanin, which causes the hair follicles to heat up and perish. The lighter the skin is in relation to the hair, the more efficient the treatment is. Laser treatment does not work on blonde, red or grey hair.

Laser hair removal is performed during the anagenic stage, when hair grows from the follicle. At any given time, 15-30% of the hairs are in this stage. Between 5 and 8 treatment sessions are therefore usually required to achieve a satisfactory result. The intervals between the sessions should be 6-12 weeks, depending on the skin area and the hair growth rate. Laser treatment is safe to use on most skin areas where unwanted hair growth occurs. It is most typically used on the legs, the bikini area, the armpits, the arms, the stomach and the chest.

Treatment procedure:

  • A cooling gel is applied onto the skin area which is to be treated
  • The correct laser frequency is chosen according to skin type and skin response. The new technology reduces pain, but there is no completely painless way to destroy hair follicles.
  • Redness can appear on the treated area for 2-3 hours following the procedure. The destroyed hairs will gradually come out of the skin during the following 1-2 weeks.
  • Avoid sunlight immediately after the procedure, and use strong sunscreen for at least 2 weeks
  • It is recommended that you avoid going to the sauna and bathing for 24 hours following the procedure, but apart from that, you can live normally
  • Around 6-12 weeks later, when the remaining hairs have visibly grown, it is time for the next treatment session
