Going beyond UV to protect the skin

Infrared radiation (IR) is electromagnetic radiation with longer wavelengths than visible light, therefore rendering it invisible to the human eye. While IR is not visible, it is extremely prevalent in daily life, with 54% of the sun’s radiation being IR. The large percentage of IR rays that are emitted and enter a person’s skin is concerning, especially if one does not know how harmful it can be. Therefore, it is important to research this and look at the potential damage that may occur.

Croda’s Solar Protection R&D group established a research partnership with Newcastle University, to investigate long wavelengths in photoprotection.1 

Experiments were conducted to determine the effects of the different components of sunlight on cells from the dermis (fibroblasts) and skin equivalents and the generation of Reactive Oxygen Species (ROS) that contribute to oxidative stress, a factor of skin  aging. 

From this research, it was found that DNA damage and ROS generation in fibroblasts is significantly triggered by IR & visible radiation. This was particularly evident for IRA rays, due to the penetration depth of longer wavelengths of light, and validates the assertion that IRA is a major contributor to photoaging.
