Hair Removal
Techniques:
Depilation is a generic term for
hair removal which affects the part of the hair above the surface of
the skin. The most common form of depilation is shaving. Another
popular option is the use of chemical depilatories, which work by
breaking the disulfide bonds that link the protein chains that give
hair its strength, making the hair disintegrate. Hair is also sometimes
removed by plucking.
Epilation is removal of the entire hair, including the part
below the skin. Some individuals may use waxing, sugaring, epilation
devices, lasers, intense pulsed light or electrology.
Laser hair removal is a
non-invasive method of photoepilation, which does not require
needles or messy chemical creams. Laser hair removal effects is usually permanent after several treatments.
- Types of Lasers and Light Sources
Used in Hair Removal?
Alexandrite Laser
The long-pulse alexandrite laser penetrates deeply into the dermis where the
hair follicles are located. The heat build-up in the hair shafts which
disables hair-follicles in the active growth phase.
Diode Laser
The diode laser contains small diodes or semiconductors that are arranged
together to produce light. The diode laser has a longer wavelength compared to
other lasers, which may improve treatment results on darker skin types.
Light-Based Sources
Intense pulsed light device operates on similar principles to other lasers.
Using the photoepilation process, the device emits a broad spectrum of light
to treat different kinds of hair and skin colors as well as hair depths.
Q-Switched Nd:YAG
YAG delivers two different wave lengths of light. One is an invisible infrared
light used for deeper penetration. The other wavelength, a green light, is used
for treating hair follicles closer to the surface.
