Lasers that permanently remove hairs emit light waves that
are absorbed by the hair pigment melanin. If the skin surrounding it is lighter
than the color of the hair, the laser energy concentrates in the hair shaft to
effectively destroy it without affecting the skin or follicle. Because lasers
target pigments, treatments are more effective when it comes to thicker hair
because they have many pigments and can absorb a lot of heat. Fine hairs cannot
absorb much heat.
The ability of the laser beam producing device to
continuously emit a very narrow bandwidth is the key to safe and effective
processing and the best clinic of Laser Hair Removal in Dubai
While the emitted laser beam only heats the hair shaft, heat is transmitted
from the hair shaft to the surrounding tissue for several milliseconds
depending on the laser pulse. Several laser devices have cooling accessories
that aim to reduce the heat of the surrounding skin in order to absorb any heat
transmitted by the destroyed hair shaft.
Pulsed light (LIP) devices are not lasers. They emit a
highly concentrated ray of incoherent traditional light, which is often
accompanied by creams or gels to burn the hair shaft. LIPs produce a wide band
of light that can heat the entire surrounding tissue, making it less effective
in terms of hair neutralization, and thus increasing the risk of burns to the
patient especially if she has dark skin.
