BIOLOGICAL EFFECTS OF LASER RADIATION ON HUMAN SKIN CELLS

Аннотация

Laser radiation has become an essential tool in modern dermatology and biomedical research due to its precise and controllable interaction with biological tissues. This article examines the biological effects of laser radiation on human skin cells, with a particular focus on cellular, molecular, and biochemical responses. Laser–tissue interaction mechanisms such as photothermal, photochemical, and photomechanical effects are analyzed in relation to different laser parameters, including wavelength, power density, and exposure duration. The study discusses how laser irradiation influences key cellular processes such as cell proliferation, apoptosis, collagen synthesis, DNA integrity, and inflammatory responses. Both therapeutic and potentially harmful effects are considered, emphasizing the importance of dose optimization and safety standards. Understanding the biological responses of skin cells to laser radiation is crucial for improving the efficacy and safety of laser-based medical and cosmetic treatments.
