The latest technology in the field of laser technology allows permanent hair removal. Removal with light has proven to be the most effective method to get rid of annoying hair permanently. The focused light transmits the light pulses to the hair root, where it releases thermal energy. The release damages the hair root to the point that it can no longer produce nutrients, so the hair can no longer grow.
Technical details
The YAG laser is a so-called solid-state laser. It emits high-energy light pulses that have a fixed wavelength of 1064 nm. The laser technology enables the light waves to have a selective effect on different color types of the skin. Surrounding tissue or blood vessels are not damaged because the wavelength is optimized for the melanin of the hair.
Operating principle
The laser beams hit the skin surface and are absorbed by the melanin. This is increased in the hair and transmits the light pulses to the hair root. There, the light energy is converted into heat and destroys the hair follicle. Therefore, no new hair can grow back.
Special features
With this modern technique, especially dark skin types can be treated optimally. Since the hairs on darker skin types are usually much stronger and darker, they often sit a little deeper in the skin. The YAG laser, on the other hand, directs the energy deep enough into the skin.
The hair cycle
The life cycle of a hair is divided into three phases: Growth phase, transition phase and inactive phase. Only hair that is in the growth phase (anagen phase) can be successfully treated, because only then is the connection between the hair and the hair root present. However, only 10-20% of all hairs are in the growth phase. For this reason, several treatments are necessary about every 4 weeks.
Course of treatment
The laser handpiece is moved over the part of the body to be treated and emits targeted laser pulses. The patient feels a slight tingling sensation, which is completely normal. Slight redness after the treatment is normal and no cause for concern. The redness usually disappears after 2-3 days.
Intensive sun exposure and preparation for treatment
Since the pigment melanin reacts to the laser energy, it is recommended to avoid intensive sun exposure so that as little melanin as possible is present in the skin. It is therefore advisable not to go to the solarium before the treatment and to reduce sunbathing to a minimum. The skin should be shaved the day before the treatment to prepare the skin optimally.
