Lasers have been used more than 30 years for the treatment of cutaneous disorders. Technological advances have led to the availability of a wide range of devices that are efficient, flexible and cost-effective, allowing for the safe and effective treatment of a growing range of conditions. Lasers emit high-intensity light from a single (monochromatic) wavelength that is absorbed in the skin by target structures and converted to heat. This main concept underpins the interaction between light and biological tissues and is known as the selective photothermolysis theory. Oxyhaemoglobin, found in the blood, and melanin, contained in hair follicles and pigmented lesions are the principal targets (chromophores) in the skin. Certain targets provide water for the tissue and pigments for tattoos. Clinically appreciable effects are created by selective heating of target structures, whereas non-target structure heating contributes to unwanted side effects.If you are looking for more tips, check out West Dermatology San Luis Obispo.
Intense pulsed light (IPL) systems are high-energy light sources, like the lasers. Nevertheless, IPLs are polychromatic, and each pulse emit several wavelengths. Filters with different cut off values tailor the spectrum of wavelengths that are released to the interest cutaneous target.
Q Laser switching in nanosecond pulses produces extremely high powered beams which cause photoacoustic damage to tattoo particles and melanosomes.
Significant advances will be discussed about the use of lasers for skin disorders. The treatment of vascular lesions such as port wine stains has been improved by new generation pulsed dye lasers and double wavelength lasers. The improved protection of the hair removal lasers has facilitated care of dark skinned individuals. Pneumatic suction devices can enhance patient comfort and efficiency and are available as a fixture for existing lasers or built into handpieces. Fractional resurfacing technology has bridged the gap between ablative resurfacing lasers and non-ablative lasers, and is the most exciting new breakthrough in this area today.
