Cutaneous photobiology

Abstract

As the outermost and largest organ of the human body, the skin is constantly exposed to solar radiation, thereby making it important to study the science of the interaction of radiation with skin called cutaneous photobiology. The electromagnetic spectrum consists of radiations of different wavelengths, but the impact of ultraviolet rays on the skin is the most important and most studied out of all. In this section, we have tried to provide a concise overview of the existing understanding of the electromagnetic spectrum, the principles of interaction of photons with skin, and its acute and chronic effects.
