Epilation with a diode laser works on the
principle of selective photothermolysis – light radiation of
incoherent wavelength, sensitive to the hair pigment – melanin. The light beam penetrates to the root of the hair
(follicle), reacts with its pigment and with the change of the light
radiation to thermal energy, the hair root is heated to an extremely
high temperature, ultimately destroying it.
hair pass through certain growth cycles during their life, for a
successful epilation result the hair must be hit during its active
growth phase (anagen), when it contains the most pigments. The number
– the percentage of roots (follicles) in the active phase is
different on different parts of the body and to a certain extent is
individual. The other roots in the given part of the body are in the
resting (telogenic) phase. Roots in the resting phase will eventually
wake up and hair will start to grow from them. Therefore,
sufficiently long pauses between the individual epilation treatments,
depending directly on the length of the resting phase on the given
part of the body, are necessary for the maximum amount of hair to
enter into the active phase and to darken and be destroyed by the IPL
light beam. In general, the best time to repeat the procedure is when
the hair starts to grow again. This phase of root growth (sleeping at
the time of previous epilation) occurs 3 – 8 weeks after the
skin is suitable for laser epilation. Parts of the body that may be
exposed to direct or even indirect sunlight should be protected using
a lotion with a higher protection factor (50). The hairs must not be
epilated with a razor or any other method that pulls the hair out
(minimally 6 weeks before the procedure). However, the hairs can be
shaved with a razor blade or trimmed with scissors.
average, epilation needs to be repeated 3-5 times, at 3 – 8 week
intervals. Any information about the results of permanent epilation
after one or two procedures cannot be true or objective. In a low
percentage of cases, depending on the individual characteristics of
the skin and hair, the number of epilation repetitions required may
be lower or higher than average. In the majority of cases, laser
epilation is accompanied by a mild skin reaction after the procedure.
The mild skin irritation may persist for several hours or up to
several days. After the procedure, sunbathing is not recommended for
at least 2–3 weeks. It is also important to use a lotion with a
high protection factor on the epilated parts of the body.
IPL epilation removes unwanted hair permanently.
However, due to the physiology of hair (see above) and many other
factors that affect hair growth (hormonal instability, endocrine
disorders, gynaecological diseases...) the results (in a very low
percentage of cases) may not correlate exactly with the theory. The
desired result is a permanent reduction of unwanted hair, i.e. a
permanent reduction in the number of hairs in a given area and a
change in their quality to fine, light hairs, which the client
already perceives as aesthetically harmless.

However, care must be taken in the following cases:

technique of removing unwanted hair, namely, using wax.
