ND:YAG laser hair removal

The latest generation of laser technology is currently the most effective method for permanent hair removal. Lasers work with thermal energy that is transmitted through focused light pulses. The pulsed laser light literally tackles the problem at the root, because it causes the targeted destruction of the hair root – the hair can not regrow.

How does an ND: YAG laser work? – Construction and technology

The Nd: YAG laser is a solid-state laser that produces extremely short, high-energy light pulses of a specific wavelength. The abbreviation Nd: YAG stands for neodymium doped laser with yttrium aluminum garnet crystal. If light falls on this crystal, the neodymium atoms are activated and the laser begins to emit light pulses.

The big advantage of laser technology: Each set wavelength has a selective effect on specific colors and structures. This allows a targeted, precise treatment – surrounding tissue and blood vessels are not damaged. The Q-switched neodymium YAG laser emits infrared radiation at a wavelength of 1064 nm, which is invisible to the human eye. This wavelength is tuned exactly to the dye melanin, which optimally absorbs laser light of this wavelength. The pigment melanin darkens hair and skin.

This laser is particularly suitable for dark skin types – they are best for a treatment with the Nd: YAG laser. People with dark skin usually have quite strong dark brown or black hair, whose roots sit very deep under the skin. The light pulses of the YAG laser can penetrate particularly deep (up to 5 mm) into the skin. They are therefore able to reach deep-seated hair roots.

The life cycle of hair is divided into three phases – growth, transitional period and inactive phase. With the laser treatment, only hair that is currently in the growth phase and has a connection to the hair root can be removed. The proportion of hair in this stage of development makes up about one third of all hair. If the permanent hair removal of all hair of a body zone is desired, the treatment must be carried out in phases with a time delay. Therefore, several treatment appointments are required, each several weeks apart. Depending on the individual starting position, 6 to 10 sessions are necessary to achieve permanently hairless, smooth skin. Even after one treatment, the hair is thinned visibly. After each session, the amount of remaining hair gradually decreases.

The principle of laser treatment

The light pulses emitted by the neodymium-YAG laser hit the skin surface, are absorbed by the dark pigment melanin in the hair and transmitted to the respective hair root. The high-energy light of the laser converts into thermal energy and permanently destroys hair follicles and hair cells. The thermal reaction remains limited to the hair root. The surrounding tissue and blood vessels do not respond to this wavelength, they are in no way impaired.

Course of treatment

During treatment, the laser head is slowly guided over the skin area to be treated. Most people feel a slight tingling. After treatment, the skin may be slightly red for a short time. Most of the symptoms resolve after 2 – 3 days at the latest.

Can I go to the sun before treatment?

The laser also reacts to melanin embedded in the skin in heavily tanned skin. Existing tan should have subsided before the start of treatment, as otherwise undesired skin reactions may occur. If possible, do not expose the affected area of ​​the body to the sun three to four weeks before the planned treatment date, or protect it with sunscreen SPF 50.

Vor und Nachbehandlung Photoepilation Fotos

To ensure successful treatment, do not bleach or epilate hair before laser therapy. Also, the removal of hair by plucking, wax or depilatory cream is to be avoided. To prepare for the treatment, please shave the part of the body to be treated the day before. If hair removal is planned on the face, make-up must be removed.
