Lasers in dermatology
Lasers in dermatology are devices that use different light energy to make some changes in the skin. The laser beam is monochromatic which means that it has only one wavelength. The wavelength determines the target structure in the skin.
There is almost no other field in dermatology that is subject to such advances and changes like laser dermatology.
The development of new lasers, as well as modifications of the old ones, continuously improve the possibilities and results. Laser treatments have become effective modalities of therapy in the fields of skin diseases and aesthetic dermatology.
Laser beam can be scattered, absorbed, transmitted, emitted.
One wavelength allows only the target structures in the skin to react, while the other structures only let the laser beam pass through. For example, 810nm (diode laser) targets the pigment in the skin, 585nm (pulsed dye laser) targets the blood vessels, 10600nm (CO2) targets the water structures.
The basic effect of every laser is to heat the target structure, with the exception of photodynamic therapy.
Lasers do not emit Ionizing radiation and cannot have negative effect on the body.
Complications are possible but are reduced to excessive heat accumulation.
They depend on the experience of the physician operating the laser, as well as on the quality of the device and safety measures that are specific to each individual laser.
