Effect of Different Wavelengths of Laser Irradiation on the Skin Cells

The invention of systems enabling the emission of waves of a certain length and intensity has revolutionized many areas of life, including medicine. Currently, the use of devices emitting laser light is not only an indispensable but also a necessary element of many diagnostic procedures. It also contributed to the development of new techniques for the treatment of diseases that are difficult to heal. The use of lasers in industry and medicine may be associated with a higher incidence of excessive radiation exposure, which can lead to injury to the body. The most exposed to laser irradiation is the skin tissue. The low dose laser irradiation is currently used for the treatment of various skin diseases. Therefore appropriate knowledge of the effects of lasers irradiation on the dermal cells' metabolism is necessary. Here we present current knowledge on the clinical and molecular effects of irradiation of different wavelengths of light (ultraviolet (UV), blue, green, red, and infrared (IR) on the dermal cells.

Automated summary

The invention of systems enabling the emission of waves of a certain length and intensity has revolutionized many areas of life, including medicine. The use of devices emitting laser light is indispensable in many diagnostic procedures and has contributed to new techniques for treating difficult-to-heal diseases. However, excessive exposure to laser radiation in industry and medicine can lead to bodily injury, particularly to skin tissue. It is crucial to understand the effects of laser irradiation on dermal cells' metabolism for the treatment of various skin diseases.
