Lasers deliver an intense beam of light which are made up of
a single wavelength or colour. Skin is essentially transparent
to light in the wavelength range of 600-1100nm (nano meters),
while melanin containing structures will absorb laser energy
of this wavelength. It is therefore possible to target the hair
follicle which has a concentration of melanin without affecting
the surrounding area.
The light energy absorbed by the melanin pigment results in
the rapid heating up of the hair follicle. This heat destroys the
cells (papilla) responsible for hair growth. If adequate heating
is achieved, then the follicle is permanently disabled resulting
in a permanent reduction in hair growth.

Melanin in the epidermis also absorbs the energy and limits the
depth of penetration of the laser light into the skin. Using a light
wavelength of 808nm enables treatment of relatively dark skin
as well as fair-skin types. However, laser hair treatment is not
suitable for Afro-Caribbean or black skin complexions. Laser
treatment is also ineffective in removal of white or grey hair.
Electrolysis should be considered as an alternative treatment.

As a guide, skin colours are classified by the Fitzpatrick skin
phototypes as described in the table opposite.

24 hours before treatment check for any reaction by treating
a small area first.
The + and - buttons increase or reduce power levels. Treat
several areas on each Power Level up to the maximum Power
Level for your skin type (see table). If you feel any discomfort,
the previous lower power level is the maximum power level
you should use.
A slight redness may occur, but not always, within an hour of
treatment. This localised redness is caused by the destruction
of the hair follicles and is quite normal. However, if any
redness remains after 24 hours this would indicate the power
level selected was too high for your skin type. Use the next
power level down during treatment.
NOTE: Skin colour varies on different areas of the body -
you may find that you need different power level settings for
different areas. Each area should be tested for the appropriate
maximum power level.
