What is an 808nm Diode Laser?

The 808nm diode laser is a type of near-infrared laser commonly used in medical and cosmetic treatments, especially for laser hair removal. The 808nm wavelength is particularly effective for targeting melanin, the pigment found in hair follicles. This characteristic allows the laser to efficiently remove hair across various skin and hair types. The diode laser’s ability to precisely target melanin makes it a powerful tool in achieving long-lasting hair reduction, making it a popular choice in skin clinics for skincare and beauty treatments.

How Does the Diode Hair Removal Work?

The 808nm diode laser hair removal treatment operates on the principle of selective photothermolysis, where the laser light selectively targets the melanin in hair follicles. The process involves several key steps:

1.Energy Transfer: The 808nm wavelength is optimal for transferring energy to melanin. Melanin, being the target chromophore, absorbs the laser light effectively.

2.Heat Conversion: The absorbed light is converted into heat. This heat is critical in damaging the hair follicles.

3.Protein Denaturation: The generated heat denatures the proteins within the hair root. These proteins are essential for the hair’s growth and nutrient supply. By denaturing these proteins, the hair root loses its ability to regenerate, leading to permanent hair reduction.

4.Controlled Light Pulses: During treatment, the diode laser emits controlled pulses of light at the targeted area. The melanin in the hair follicle absorbs the light, leading to a localized increase in temperature. This process effectively damages the hair follicle while minimizing the impact on the surrounding skin.

The 808nm diode laser effectively destroys hair follicles while minimizing damage to surrounding skin, making it ideal for laser hair removal on various skin types.
