The technology of laser hair removal is based on selective photothermolysis. The laser light reaches the
hair fllicles. The light is absorbed and transformed into heat.As a result, the cells responsible for hair gro-
wth are damaged and hair stops growing.
The diode laser has been shown to be the effective in hair removal.
●755 nm is a wavelength used to remove light, thin and shallowly embedded hair
●808 nm is a wavelength used to remove dark, thick and deeply embedded hair
●940 nm is a wavelength used to remove dark and light, shallowly embedded hair
●1064 nm is a wavelength used to remove shallowly embedded, dark hair
755nm: For the widest range of hair types and colors.
The 755nm wavelength offers more powerful energy absorption by the melanin chromophore , making
it ideal for the widest range of hair types and colors, especially light-colored and thin hair.
808nm: Half the treatment time.
The classic wavelength in laser hair removal, the 808nm wavelength offers deep penetration of the hair
fllicle with high average power, a high repettion rate, and a large spot size for fast treatment.
940nm: Effectively penetrates deep and is absorbed by the target chromophore.
The adequate pulse duration, energy density, and epidermal cooling ensure sufficient thermal damage
to the target tssue without damaging the surrounding tissue to achieve effective hair removal.
1064nm: Specialized for dark skin types.
The 1064nm wavelength is characterized by lower melanin absorption, making it a focused solution for
darker skin types.
