We now know that the best way to prevent skin cancer and sun damage to the skin is to use a broad-spectrum sun protectant daily - one that blocks both ultraviolet A light (UVA) and ultraviolet B light (UVB). The shorter wavelength UVB rays penetrate only the top layer of the skin and are the cause of sunburn. The longer wavelength UVA rays penetrate into the deeper layers of the skin. UVB rays are strongest in summer, while UVA rays do not vary by season and are present all year round. UVA rays contribute to premature aging and the formation of fine lines and wrinkles by breaking down the collagen and elastin that keep skin firm and smooth. UVB and UVA rays contribute to the development of skin cancer, including melanoma.
Most sunscreens give excellent protection from UVB, but there are fewer that give good protection from UVA. To get the best broad-spectrum protection, look for sunscreens that are at least SPF 15 and contain either Parsol (avobenzone) or physical blocking agents such as titanium dioxide or zinc oxide.
Even though today's sunscreens are better than ever before, don't get a false sense of security and rely totally on sunscreens to protect your skin. It's still very important to wear hats, sunglasses and protective clothing. One of the most effective sun protection measures you can take is to plan your outdoor activities early or late in the day so that you avoid the peak midday hours of intense sun.
