Laser surgery employs focused light beams instead of traditional tools for treatments. The term LASER, standing for "Light Amplification by Stimulated Emission of Radiation," was coined in 1960 when the first laser was created. Since then, ongoing modifications have transformed medical and surgical procedures, particularly in treating various skin lesions and disorders.
In surgery, lasers serve multiple purposes, including tumor removal, sealing small blood vessels to prevent blood loss, and reducing swelling and preventing the spread of malignant cells. Additionally, lasers are effective in eliminating or improving skin conditions like warts, moles, tattoos, birthmarks, scars, and wrinkles.
Directed onto the skin, laser beams can be reflected, scattered, absorbed, or transmitted through different skin layers. Chromophores, specific components of the skin, absorb the light, leading to physical, mechanical, chemical, or thermal changes in the tissue. Various types of lasers, like the carbon dioxide laser the YAG (neodymium, or yttrium aluminum garnet) laser, and the argon laser, cater to a wide range of medical treatments.
