non-invasive solutions


The primary principle behind Laser Hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue. Lasers used in laser hair removal devices, cause localized damage by selectively heating dark target matter, (melanin), in the area that causes hair growth, (the follicle), while not heating the rest of the skin including melanin in the skin.

Melanin is considered the primary chromophore for all hair removal lasers currently on the market. Melanin occurs naturally in the skin, and gives skin and hair their color. There are two types of melanin in hair: Eumelanin, gives hair brown or black color, while pheomelanin gives hair blonde or red color. Because of the selective absorption of photons of laser light, only black or brown hair can be removed. Laser works best with dark coarse hair.

Light skin and dark hair are an ideal combination, being most effective and producing the best results, but new lasers, such as MeDiostar NXT, are now able to target dark black hair in patients with dark skin.

the wavelength of the high-power diode laser MeDioStar was chosen in a way that the absorption of the light is high for melanin, but selective to the melanin in the hair follicle because the hand piece of the MeDioStar includes a strong skin cooling, which always cools the most superficial layer of the skin immediately before the laser pulse and as such protecting the melanin in the skin. It also makes the treatment more convenient for the patient. At the same time it is possible to treat even dark skin types. In addition a special treatment mode (SmoothPulse) for larger areas can be used with our new MeDioStar NeXT making the laser pulse sensation hard to feel, even for sensitive patients. Due to the optimal design of the MeDioStar laser, side effects of more than slight redness and swelling around dark hair are very rare.
