One of the sectors affected by technological developments
for aesthetics is the cosmetic dermatology sector. The newest
products of the developing technology in this sector are laser epilation
systems, especially Alexandrite and Nd: YAG Laser Systems.
Lasers emit light energy of certain wavelengths. This
energy is absorbed by the melanin pigment in the hair follicles and converted
into heat energy. Heat energy causes the hair root’s temperature to
increase. Hair follicles with increased temperature are destroyed by
burning, and as a result, the damaged hair follicle cannot grow hair again. When
laser beams are applied to the skin, they are only absorbed by melanin
pigments, so they do not damage other skin cells.
It varies depending on the width of the application area
and the system to be used. For example; While the mustache and chin
area is completed in 5 minutes, the entire leg area is completed in 45 minutes.
Alexandrite lasers are the most commonly used lasers with a
wavelength of 755 nanometers for epilation. The most important difference
of this laser system from the others is that the distance it takes in the skin
is the least, but this distance is usually sufficient to reach the hair root. Another
feature is that it is one of the lasers, which is very much held by the melanin
pigment, which is in the structure of the hair and gives the color of the hair.
It is an advantage for those with light skin type and dark hair color. However,
it is not recommended for people with dark skin color.
These are lasers with a wavelength of 1064 nanometers and
less absorption by melanin pigments. However, if Nd: YAG lasers with high
output power are used in epilation, less absorption can be turned into an
The high absorption of laser beam does not increase the
success rate in epilation. On the contrary, there is a possibility of damaging
other cells in the skin. Ruby lasers are the type of laser that emit the
rays with the highest absorption by the melanin pigment. Ruby lasers are
hardly used today.
