HOW DO LASERS WORK?
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.
SUITABLE SKIN TYPES
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.
PATCH TEST
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 testing
a few hairs in the area to be treated.
The (+) and (-) buttons increase or reduce power levels.
Treat 2–3 hairs 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.
After 24 hours if any of the test areas appear red or
inflamed for any particular power level, select a lower level
for 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.
