SPF? UVA? UVB? Here's how to understand sunscreen labels and find the one that's best for you:
Not all sunscreens are broad spectrum, so it is important to look for it on the label. Broad spectrum sunscreen provides protection from the sun’s ultraviolet radiation. There are two types of UV radiation that you need to protect yourself from – UVA and UVB. Broad spectrum provides protection against both by providing a chemical barrier that absorbs or reflects UV radiation before it can damage the skin.
As of June 2011, sunscreens that pass the broad spectrum test can demonstrate that they also provide UVA protection. Therefore, under the label requirements, for sunscreens labeled"Broad Spectrum SPF [value]", they will indicate protection from both UVA and UVB radiation.If your skin is fair, you may want a higher SPF of 30 to 50.
There is a popular misconception that SPF relates to time of solar exposure. For example, many people believe that, if they normally get sunburned in one hour, then an SPF 15 sunscreen allows them to stay in the sun for 15 hours without getting sunburn. This is not true because SPF is not directly related toThe sun is stronger in the middle of the day compared to early morning and early evening hours. That means your risk of sunburn is higher at mid-day.
