Sunburn. Why should you worry?
What to look for when looking for the right sun protection.
Why everyone should worry about sunburn.
Ultraviolet (UV) radiation from the sun can damage the skin and is a well known risk factor for the development of skin cancer. Sunscreens can help prevent that risk; however, choosing the right one can seem like a challenge.
SPF, or sun protection factor, is often the first thing that comes to mind when comparing sunscreens. However, SPF mainly measures protection against UVB (the wavelengths that cause sunburn). UVA radiation also increases the risk of skin cancer and can penetrate deeper into the skin, playing a major role in photoaging (wrinkles, brown spots, dilated blood vessels).
According to the FDA, sunscreens with UVA protection and an SPF of at least 15 can now display that “if used as directed with other sun protection measures, may decrease the risk of skin cancer and early skin aging caused by the sun.” Dermatologists recommend an SPF of at least 30, and make sure that consumers check the label for that statement. Another new requirement is that sunscreens may now claim that they are water resistant for either 40 minutes or 80 minutes based on standardized testing.
