L A S E R : Light Amplification by Stimulated Emission of Radiation.

Laser has a specific wavelength high-energy beam of light. That can transfer its energy harmlessly through the skin. Pigment (Melanin) contained in the hair shaft & follicles absorb the energy generated by the laser. This absorption turns the light energy into heat and damaging the surrounding cell layers, which are responsible for hair growth. If enough damage is done, this will causes necrosis of papilla and permanent destruction of the hair follicles to stops the growth of the hair. That beam of light can vary in terms of their strength and type. MeDioStar Diode Laser has become a synonym for safe hair removal, also for darker skin types. Its high power reaches hair follicles at deeper levels. Even when using higher energy densities, the application always remains delicate, guaranteeing low risk and gentle treatment for patients

Intense Pulsed Light systems are different from lasers in that they can deliver hundreds of wavelengths (or colors) in each burst of light. In the case of hair removal certain filters are used to target the hair follicles with these flashes of light energy. The burst of light energy causes damage to the follicle in the same way as a laser.

Why Laser Hair Removal?

Laser hair removal is a faster and non-invasive medical procedure. Threading, plucking, waxing, and use of depilatory creams are temporary methods that have to be repeated frequently. Electrolysis on the other hand can eventually offer long lasting results, but it is a painful, invasive, and tedious process. Laser can treat hundreds of hair follicles at a time and therefore treat an area in seconds where it would take threading, plucking, or electrolysis an hour or so.

How does Laser works?

A laser is an intense source of light that produces heat. Its target is melanin in the hair shaft. The 810nm wavelength of Diode laser is attracted mostly to the melanin. The light is pulsed for a fraction of a second and the heat is then pulsed 60° to 70° C into the hair’s melanin. That thermal damage causes necrosis of papilla and permanent destruction of the hairs in anagen phase or growth phase and the hair falls out.

The effect is most productive during the anagen or 'active' phase of hair growth. The anagen phase is when new hair starts to grow. In other phases the hair is simply resting and no longer growing, or is ready for a new one to form. The amount of time that a hair follicle stays in the anagen phase is genetically predetermined and will vary slightly within the population and on different areas of the body. During this period of growth, the hair follicle has increased pigmentation and growth of new cells that makes it more open to damage from light energy of laser and IPL.
