Lasers are often described as photon emitting beams in a coherent and consistent way via an optical source. They were invented many years ago and were not designed for commercial usage as the technology was in its infancy. Technological advancements in all fields of science have helped in improving the functioning and scope of lasers in recent years. Lasers are now being used in different sectors such as science, industry, medicine, and consumer electronics.
Lasers can be classified according to the type of application for which they are used. Lasers are increasingly being used in different branches of medicine such as dermatology, surgery, plastic surgery, dentistry, ophthalmology, and cosmetic procedures. Lasers used for skin treatments are often referred to as cosmetic lasers that produce an intense beam of light with insignificant dispersion over a short distance.
One of the most common uses of cosmetic lasers can be seen in resurfacing of skin that may have been damaged due to scars and wrinkles. The laser removes thin layers of irregular skin in multiple sessions. Another common use is related to the removal of bodily hair. Tattoos can also be removed using cosmetic lasers in multiple sessions depending on color and depth of pigment used in tattooing.
Cosmetic lasers are also used for the treatment of various skin conditions such as Port Wine Stains, spider nevi, warts, acne scars, moles and nevi, and Lentigenes (age spots). They are used for precise tissue destruction of skin lesions without affecting the skin tissue in the surrounding areas. The water present in naturally occurring pigments such as melanin and hemoglobin absorbs laser beams used in non-invasive cosmetic surgical procedures.
The desire to look good is inherent in every human being, which is the reason why an increasing number of people are opting for cosmetic laser surgeries that are safer and less painful than traditional abrasive methods of skin rejuvenation.
