6.4 Epilation
The removal of unwanted hair growth is undoubtedly one of the oldest cosmetic treatments
performed by men. Over the past years, it has experienced greatly increased popularity. The
methods range from regularly repeated shavings to a more lasting, though very painful wax
epilation, to extremely time-consuming hair removal by means of electrolysis needles, which on the
other hand can yield a rather lasting success.
Each of these methods, and, naturally, also laser epilation which is comparatively more pleasant,
aims to remove hair with a maximum lasting effect.

simply plucking out unwanted hair. It will grow again. This means that the structures responsible for
hair growth have to be destroyed, too.

be destroyed or at least impaired in their action for this reason.

located down to 5 mm beneath the skin
surface. Therefore, the laser spot should be as large as possible to ensure a depth effectiveness of
laser radiation.
A clinical study performed with the MeDioStar device showed that a spot size of 1.1 cm² is sufficient
to treat hair on the legs effectively. A further enlargement of the spot did not achieve better results.
The smaller spot size of 0.5 cm² led to a lower effectiveness of ca. 10%.
