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.
