New Zealand has some of the highest ultraviolet radiation (UVR) levels in the world. There are three types of UVR; UVC, UVB which effects the outer layer of skin and UVA which penetrates the layers of skin and can change the DNA of skin cells. Excessive exposure to UVR without using sun protection can result in skin damage. While different skin types vary in their susceptibility to and severity of skin damage, it is important for everyone to protect themselves. Sunburn causes inflammation and breakdown of skin cells. Prolonged sun exposure can damage multiple layers of skin, resulting in severe burning. The potential for serious injury from the sun should not be underestimated, particularly the long-term risks associated with sun damaged skin. Overview of sunburn and the types of sunburn Burn severity is typically measured in three degrees. First-degree burns are the least severe and are characterised by damage occurring only to the outermost layer of skin and shown by redness, inflammation and moderate pain. Second degree burns cause damage to the skin layer beneath, which contains sweat and oil glands, capillaries, hair follicles and nerve endings. This damage results in blistering, weeping and incredible amounts of pain. Lastly, there are third degree burns. This involves all skin layers, while this is much rarer to occur from sun exposure alone, it is possible. What are the risks of sunburn long term?
