ly because they think it provides more protection, when in fact, it does not. Manufacturers are no longer allowed to use words like “waterproof,” “sweat proof” or “sunblock” as these terms are misleading. What you might on sunscreen labels instead is “water-resistant” with a time limit of 40 or 80 minutes before the sunscreen becomes ineffective. It is important to know that these new FDA guidelines are still in the process of becoming completely enforced, as it takes time for manufacturers to submit required documentation to change labeling. It is always important to read the label of any sunscreen product you are considering. Recommendations for Sunscreen Use The American Academy of Dermatology (AAD) recommends wearing an SPF of 30 or higher every day, not only when you are lying out by the pool or on the beach. The sun’s rays can still be damaging, even on a cloudy day. Most people do not put on enough sunscreen. In fact, according to the AAD, most people only apply about 25 to 50% of what they should put on to be fully protected. As a general guideline, you should generously apply one ounce to all areas of the skin that will be exposed to the sun. Sunscreen should be applied to dry skin 15 minutes before you go outside and reapplied every two hours, or after swimming or heavy sweating. What about Makeup and Moisturizers? Some cosmetic products and moisturizers do contain a small amount of SPF, but if you are trying to protect yourself from sun damage or skin cancer that will not be sufficient protection. Dr. Kim recommends an application of dedicated sunscreen underneath your moisturizer and makeup rather than relying on the SPF of your cosmetic products. Ultimately, you must remember that no sunscreen is perfect. Wearing long sleeves and a hat and staying in the shade as much as possible are also important precautions to take to prevent sun damage or potentially deadly skin cancer.
