Diode Lasers Technology for Hair Reduction

Diode lasers use semiconductor technology that produces a coherent projection of light in the visible to infrared range. It uses a light beam with a narrow spectrum to target specific chromophores in the skin. Compared to other laser systems such as the Ruby and Alexandrite, the 808nm diode laser wavelength offers the deepest penetration levels and superior melanin absorption. 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. These unique characteristics make the diode laser the most suitable technology for laser hair removal, enabling safe and effective treatment of all skin and hair types, in all body areas.

How Does A 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 that 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. 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 - Gold Standard

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.

Diode Laser Technology for Hair Reduction Results

Repeated treatments are usually necessary because hair growth and loss naturally occur in a cycle, and laser treatment works best with hair follicles in the new-growth stage.

The Diode Laser hair reduction method uses groundbreaking diode technology to offer a simple, one-stop solution for truly effective hair removal. The professional diode laser machines feature the Strong TEC Sapphire Contact Cooling technology to avoid injury to the surrounding tissue. The sweeping In-motion delivery technique keeps the laser in constant motion ensuring full coverage.
