So we all know the importance of wearing sunscreen for the prevention of cancer and premature aging, but there are a few tips and tricks that will help you get the most out of your products and keep you and your family safer.Remember the 20-1-2 rule. For sunscreen to be effective, it must first properly absorb into the skin, so apply it 20 minutes prior to exposure. Most people do not apply enough product, so use a shot glass sized amount (One fluid ounce) when slathering up. Lastly, sunscreen must be reapplied every two hours to ensure its effectiveness. If you are in water, then reapply every hour. Sunscreen does expire. Most sunscreens do have an expiration date of three years stamped on the packaging. If you are properly applying sunscreen as often as you should though, one bottle or tube should never ever last you the entire season. If at any time a sunscreen becomes separated, watery, chunky or the smell changes, throw it out. Properly store your sunscreen. Sunscreen needs to be kept at room temperature to ensure your safety and the effectiveness of the product. Never leave sunscreen in your car or in direct sunlight as high temperatures breakdown and destroy the formulation, making it less effective in protecting your skin. Keep your sunscreen with you, as you need to apply it often anyhow. Keep it in your beach bag and in the shade, or throw it in your cooler. Try something new. Most people who avoid using sunscreen, say it is because they do not like the greasy or heavy feel of it. With new technologies and delivery systems there is a sunscreen for everyone. Spray sun protection is growing in popularity as it absorbs quickly and leaves little residue. Just make sure you are thorough in your application and always rub it in, even If the bottle says “No rub” and do not spray directly onto the face, rather spray it into your hands and apply with your fingertips. The cliché imagery of the lifeguard with the chalky white nose is also a thing of the past as formulations for physical sunscreen have advanced. Dry pressed or loose mineral sunscreens are light and can easily be used in conjunction with your makeup routine. Another advantage of physical sunscreens such as Zinc Oxide and Titanium Dioxide is that they give immediate sun protection because they physically block and reflect UV rays. You can build your protection. A study conducted by the Department of Dermatology at the Bispebjerb Hospital in Copenhagen found that applying sunscreen three times daily built up enough product in the outer layers of skin to give a more prolonged protection factor. I recommend to my clients that a week before going on vacation to apply full body sunscreen morning, noon and just prior to going to bed. time now . A “base” of sunscreen is safe, a “base tan” is not.
