Which wavelength is commonly used for hair removal procedures?

The wavelength commonly used for hair removal procedures is 755 nm. This wavelength is within the range of the near-infrared spectrum and is particularly effective for targeting the melanin found in hair follicles. The light at this wavelength is well absorbed by the pigment in the hair while causing minimal absorption in the surrounding skin, making it ideal for hair removal treatments.

The 755 nm wavelength is known for its optimal balance of depth of penetration and selectivity for melanin, which enables effective hair reduction across a variety of skin types. Additionally, it provides a relatively gentle treatment that minimizes the risk of skin damage compared to wavelengths that are less selective.

While other wavelengths, like 532 nm and 1064 nm, can also be used for laser treatments, they are typically better suited for different skin conditions or types of vascular lesions rather than hair removal specifically. The 1470 nm wavelength is more commonly associated with procedures targeting deeper tissues and specific conditions, such as certain types of vascular or soft tissue lasers, rather than being primarily used for hair removal.
