A diode laser uses semiconductor technology that produces a coherent projection of light in the visible to infrared range. Diode Laser Hair Removal is popular with people wanting a solution to hair removal that is more permanent, complete, fast, pain-free, effective than some other methods. Using lasers to remove hair works by stopping the hair follicles from growing new hairs.
The Diode Laser System can emit laser light of 808nm wavelength. It can be absorbed by the melanin located in the hair follicle, so as to destroy the hair follicle. The hair shaft can also absorb the energy from laser lights, so as to be destroyed and gasified. Then the unwanted hair can be removed completely and permanently.
How Does A 808nm Diode Laser Work?
Diode lasers use the principle of selective photothermolysis to target specific chromophores in the skin, usually melanin or blood. The lasers damage the chromophores by selectively heating them while leaving surrounding tissue unharmed. When treating unwanted hair, for example, the melanin in the hair follicles is targeted and damaged which results in the disruption of hair growth and regeneration. A diode laser can be complemented by cooling technology or other pain-reducing methods which improve treatment efficacy and patient comfort. Permanent hair reduction on all pigmented hair and all skin types – including tanned skin. This flexibility makes it ideal for both physicians and medical spa professionals.
Diode Laser hair removal works by destroying the root of the hair follicle. During treatment, flashes of light are distributed over the skin and absorbed by the melanin in the hair follicle. The energy from the laser heats up and damages the hair follicle, successfully stunting the cells that stimulate regrowth. It is important to note that hair grows in a cycle, and that hair removal is only effective during the active growth stage.
Three Stages Of Growth
Every hair goes through three stages of growth: the anagen phase, catagen phase, and telogen phase. The anagen phase, also known as the growth stage, is the duration in which your hair actively continues to grow. The catagen phase, also known as the transitional phase, is when the hair follicle shrinks and detaches from the papilla, a structure at the base of the follicle. The telogen phase, also known as the resting phase, is when the old hair is released and falls out. When the old hair sheds, the hair follicle re-attaches to the papilla and re-enters the anagen phase, repeating the cycle.
Each hair in your body can be at a different stage in the growth cycle at any given time. Thus, to target the hair during the anagen phase, multiple laser treatments are necessary to target the numerous hair follicles during their growth stage.
Optimal 808nm Wavelength
808nm wavelength offers deep penetration of the hair follicle with high average power, a high repetition rate. The 808nm has a moderate melanin absorption level making it safe. Its deep penetration capabilities target the Bulge and Bulb of the hair follicle while moderate tissue depth penetration makes it ideal for treating the arms, legs, cheeks, and beard.
