A real sunburn remedy?

Sunburn is not only unsightly, it is commonly very painful and is a significant risk factor for certain types of skin cancer. Ultraviolet light initiates various biochemical cascades involving the inflammatory response as well as potentially causing damage to the cells' genetic material. Researchers at the University of California, San Diego School of Medicine and their colleagues. Nevertheless UV light can be beneficial in skin disorders such as psoriasis so finding a way to prevent inflammatory damage is important. Richard Gallo and colleagues have now shown that RNA is involved in UV damage and point to a way to inhibit this response so that UV can be used in therapy without the risk of skin cancer.
