Lasers have been using more than 30 years for the diagnosis of cutaneous diseases. Technological advances have led to the availability of a wide range of devices that are powerful, versatile and cost-effective, allowing for the safe and effective treatment of an increasing range of conditions. Las Vegas Skin & Cancer Warm Springs is an excellent resource for this. Lasers produce high-intensity light from a single (monochromatic) wavelength that is absorbed in the skin by target materials and transformed to heat. This main concept underpins the relationship between light with biological tissues and is regarded as the selective photothermolysis theory. Oxyhaemoglobin, contained in the blood, and melanin, contained in hair follicles and pigmented lesions are the principal targets (chromophores) in the skin. Other targets provide water for the tissue and pigments for tattoos. Clinically appreciable results are created by selective heating of target structures, whereas non-target structure heating contributes to undesirable side effects.
Intense pulsed light (IPL) devices are high-energy light sources, like the lasers. However, IPLs are polychromatic, and each pulse emit several wavelengths. Filters with various cut off values customize the spectrum of wavelengths that are released to the purpose cutaneous target.
Q Laser switching in nanosecond pulses produces extremely high powered beams which cause photoacoustic damage to tattoo particles and melanosomes.
Important developments should be addressed about the usage of lasers for skin disorders. The treatment of vascular lesions such as port wine stains has been optimized by new generation pulsed dye lasers and double wavelength lasers. The enhanced safety of the hair removal lasers has enabled treatment of dark skinned individuals. Pneumatic suction devices can improve treatment comfort and efficiency and are available as a fixture for existing lasers or integrated into handpieces. Fractional resurfacing technology has bridged the difference between ablative resurfacing lasers and non-ablative lasers, which is the most promising new breakthrough in this sector today.
