For more than 30 years, lasers have been used to treat cutaneous disorders. Technological advancements have resulted in the availability of a wide variety of instruments that are efficient, flexible, and cost-effective, allowing for the safe and effective treatment of a growing number of conditions. Lasers produce high-intensity light with a single (monochromatic) wavelength that is absorbed and converted to heat energy by target structures in the skin. The theory of selective photothermolysis is the main concept that underpins the interaction between light and biological tissues. In the skin, the key targets (chromophores) are oxyhaemoglobin, which is found in blood, and melanin, which is found in hair follicles and pigmented lesions. Tissue water and tattoo pigments are two more goals. Heating target structures selectively creates clinically important effects, whereas heating non-target structures induces unintended side effects.

IPL (intense pulsed light) devices, like lasers, are high-energy light sources. IPLs, on the other hand, are polychromatic, emitting several wavelengths for each pulse. Filters with various cutoff values customise the wavelength range released to the cutaneous target of interest.
Q As lasers are turned on and off, extremely high powered beams are emitted in nanosecond bursts, causing photoacoustic damage to tattoo particles and melanosomes.
There will be a discussion of significant advancements in the use of lasers for skin disorders. The treatment of vascular lesions such as port wine stains has been improved thanks to new generation pulsed dye lasers and dual wavelength lasers. The enhanced protection of lasers for hair removal has made it possible to treat people with dark skin. Pneumatic suction devices, which can be added to existing lasers or incorporated into handpieces, can improve treatment comfort and efficacy. Fractional resurfacing technology is the most exciting new advancement in this area, bridging the gap between ablative and non-ablative resurfacing lasers.
