Newcastle University researchers have identified an antioxidant Tiron, which offers total protection against some types of sun damage and may ultimately help our skin stay looking younger for longer. Publishing in The FASEB Journal, the authors describe how in laboratory tests, they compared the protection offered against either UVA radiation or free radical stress by several antioxidants, some of which are found in foods or cosmetics. While UVB radiation easily causes sunburn, UVA radiation penetrates deeper, damaging our DNA by generating free radicals which degrades the collagen that gives skin its elastic quality.
