The Techno­logy

General Information

Modern technology in the form of laser technology makes permanent* hair removal with light possible. Hair removal with the help of light has proven to be the most effective way to get rid of unwanted hair growth. And not just temporarily, but permanently*. Another technique offered in Kaiserslautern is the ND:YAG laser. Here, too, the aim of the treatment is to denature the protein in the hair roots. The protein is responsible for the growth of the hair. The laser transmits the energy of the focused light to the hair root, where it then exert its effect.

Technical background

The ND:YAG laser is a solid-state laser. The laser emits light pulses with high energy. The wavelength is fixed at 1064nm.

Due to the specific wavelength, the light has a precise effect on different types of hair and skin. Due to the selective wavelength, the surrounding blood vessels or tissue cannot be damaged. The wavelength is optimized for the effect of the energy on the melanin of the hair.

What types of hair can be treated?

Dark hair in particular can be addressed well with this technology. The roots of these hairs are often located deeper under the skin surface. However, the ND:YAG laser can conduct the energy to the deeper hair roots.

Which phases are good to use?

The cycle of each hair can be basically divided into 3 phases. A distinction is made between the growth phase, the transition phase and the inactive phase. For optimal treatment, the hair in question must be in the growth phase, because only then there is an active connection between the hair shaft and the root. This allows the light to reach the hair root. In total, usually about 10% of the hair is in the active phase and can be treated.

Treatment process

What happens in the body?

The device sends laser beams to the skin or rather the hair. The melanin in the hair absorbs the energy of the light and transmits it directly to the root. The energy contained in the light is converted into heat in the hair root and the protein contained in the follicle of the hair is denatured. As a result, new hair can no longer grow.

How does the treatment work?

Before treatment can begin, you should shave the affected area. The day before the respective treatment is best, so that the skin can calm down.

The handpiece of the ND:YAG laser is placed on the appropriate part of the body and a light pulse is then emitted. Customers often feel a slight tingling sensation. This comes from the energy of light and is normal. Therefore, the skin may turn slightly red but should subside after about two to three days. If this is not the case, make an appointment with us.

After the treatment

What should you avoid?

You should avoid intensive sunbathing or visits to the solarium. The treatment causes the skin to react to the light energy. It also does this when it is exposed to sunlight or UV radiation. So that this energy does not add up and has a negative effect on the skin and possibly cause pigment spots, UV radiation or other skin irritations should be avoided.
