What is the wavelength of Alexandrite laser used for hair removal?

The wavelength of the Alexandrite laser used for hair removal is indeed 755nm. This specific wavelength is significant because it falls within the range of the near-infrared spectrum, which is highly absorbed by melanin in the hair follicle while minimizing absorption by surrounding tissues. This selective photothermolysis is crucial for effective hair removal; it allows the laser to target and damage the hair follicle specifically, leading to effective long-term hair reduction.

The 755nm wavelength also strikes a balance between penetration depth and specificity, making it suitable for a variety of skin types, especially lighter skin with darker hair. The laser's ability to treat larger areas quickly further enhances its effectiveness in a clinical setting for cosmetic hair removal procedures. The Alexandrite laser is recognized for its efficiency and speed, accommodating patients' needs for rapid treatments while providing optimal results.
