IPL technology – how it works
The IPL 7800 Cool Pro is a light-based device for long-lasting hair removal for private use.
The light-based hair removal process is a well-known and proven method. In over 15 years
of clinical applications around the world, it has proven to be a safe and effective method
for achieving long-lasting hair reduction. The additional cooling function can make usage
more pleasant.
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 treatments with IPL.
Anagen – growth
Although the duration of a complete hair growth cycle differs from person
phase
to person and depends on the area of the body the hair is growing on, the
cycle generally lasts 18–24 months.
Please note that at least one complete hair
growth cycle is required in order to achieve
