Q&A on the Laser Treatment
|Is the laser treatment painful?
|There is almost no pain since the irradiation time of the
laser is 1/1,000 sec.
|Is there any harmful side effects?
|There is only few side effects or after-effects and safety
is confirmed since the laser is absorbed selectively by the
|Is it expensive?
It varies from few thousand yen to few ten thousand yen,
depending upon the size and number of the spots, freckles
About the Laser Treatment
the laser within visual range is irradiated on the skin surface,
a part of it reflects on the surface and the rest penetrates
the skin. The strength of the laser lessens as it is scattered
and absorbed at each layer of the epidermis and cutis. As for
the treatment of the melanin pigmentation, the longer the wavelength,
increases the effect against the melanin of depth as the decrease
of laser by scattering lessenes, although the absorption lessens.
The laser is the best-balanced wavelength agaist the absorption
of the pigment and the normal tissue. The shorter the irradiating
time, the less the solidification death of the surrounding (normal)
tissue by the heat conduction, which is necessary for the treatment
of depth. LRT-301A/QS qualifies the above conditions as the oscillating
wavelength 694mm and irradiating time 30ns, which is developed
as the device to treat the Ota's nevus, etc.
If the laser is irradiated, it is absorbed by the pigment near
the surface. The pigment which absorbed laser is destroyed
and phagocytized by macrophage.
As the irradiation is repeated, the pigment of the surface layer
is destroyed gradually and the laser reaches deep to the skin.
The pigment will disappear.
