Laser hair removal is aimed at
destroying the hair bulb. It is the bulbous region,
constituting the base of the hair. In the case of dark hair,
this area is pigmented. A laser is a device that
emits a very special light because it is constituted of a single wavelength,
defining its monochromatic character.
According to this wavelength, specific
to each laser, the photons constituting this light will be more or less
absorbed by the different structures encountered, in particular as a function
of the color of these. Thus, a pigmented hair
represents a brown or black target Laser Hair Removal in Dubai Depilatory lasers are strongly absorbed
by this color due to the skin's natural pigment, melanin. Once
absorbed, the light is transformed into heat. This
will destroy the hair bulb and ensures the phenomenon of lasting hair removal.
The target of the laser is therefore
not actually the bulb but the pigment which gives it its brown color. There
are two essential consequences: on the one hand, if the dark hairs can be
effectively destroyed, the laser is not working on unpigmented bristles, such
as white, blond or red hairs. Laser will not differentiate between the melanin
pigment of the bulb and that present in abundance in the epidermis of a
pigmented skin naturally pigmented, or as a result of tanning.
