How does the light remove the hair?
Light-based hair removal is founded on the principle of selective photothermolysis, which
uses optical energy to deactivate hair growth. To achieve such a thermal effect, the hair root
must selectively absorb the light energy and convert it into heat.
This selectivity is achieved when the optical energy that is released into the tissue is mainly
absorbed by the melanin pigment in the hair. The high-energy light is converted into thermal
energy (heat), which ultimately deactivates hair growth.
What effect does the hair growth cycle have on light-based hair removal?
Every hair on our body goes through the three phases of the hair growth
cycle: anagen, catagen and telogen. Only hairs that are in the anagen phase,
or growth phase, respond to treatment with IPL.
Although the duration of a complete hair growth cycle differs from person
Anagen – growth
phase
to person and depends on the area of the body the hair is growing on, the
cycle generally lasts 18 to 24 months.
Please note that at least one complete hair
growth cycle is required in order to achieve
permanent hair removal using the beurer IPL
