The Diode laser 4 wavelength is 755nm 808nm 940nm 1064nm.
755nm offers more powerful energy absorption by the melanin chromophore, making it ideal for light colored and thin hair. It targets the Bulge of the hair follicle and is especially effective for superficially embedded hair.
808nm is classic wavelength in laser hair removal, the 808nm wavelength, offers deep penetration of the hair follicle with high average power, suitable for most skin types and hair types .
940 nm wavelength provides better absorption by oxyhaemoglobin (coagulation of micro vessels that feed the hair root) and a moderate penetration depth that makes it suitable for treating all hair types.
Melanin absorption is low, making it very safe for working with dark photo types.
1064nm wavelength is characterized by lower melanin absorption, making it a focused solution for darker skin types. At the same time, the 1064nm offers the deepest penetration of the hair follicle.
