Abstract:
Lasers have become a critical part of the dermatologist's armamentarium for modulating cutaneous biology, both in treating skin disorders and providing tangible cosmetic alterations to the skin. Although modern lasers are relatively straightforward to use, they are powerful tools that are capable of considerable damage when used incorrectly. Developing an understanding of how these lasers function is essential to their safe and responsible use. This article will discuss the fundamental concepts of lasers in dermatology and the cutaneous interactions they cause.

The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
