Infrared Radiation: A Double-Edged Sword for Skin Health
Researchers from University of California Irvine, University of Oklahoma and Henry Ford Medical Center have highlighted the complex effects of infrared radiation (IR) on human skin. The study explores both the detrimental and beneficial impacts of IR, providing a comprehensive overview of the current understanding of how this type of radiation influences skin health.
Infrared radiation, which constitutes about 40% of the solar radiation reaching Earth, penetrates deeper into the skin compared to ultraviolet radiation (UV). The review notes that while IR can contribute to skin aging (photoaging) and potentially play a role in skin cancer (photocarcinogenesis) due to its thermal effects, it also offers promising benefits. For example, IR has been shown to support skin rejuvenation, wound healing, and hair restoration when used in controlled doses.
Interestingly, IR may also have protective properties against the harmful effects of UV radiation, highlighting its potential in photoprotection strategies. However, the review sheds light on the need for further research to determine the optimal conditions under which IR can be safely harnessed for therapeutic purposes.
Overall, this publication highlights the dual nature of infrared radiation, advocating for a balanced understanding to guide future research and skincare practices.
