We hope you and your family make it a great Labor Day weekend. Since its the “last weekend” of the summer make sure to be aware of the heat and sun. Here is a quick safety moment about the use and value of protecting your skin from the sun. Thank you to Astava for this great safety moment.
Choose a sunscreen with “broad-spectrum” protection. All sunscreen products protect against UVB rays, which are the main cause of sunburn. But UVA rays also contribute to skin cancer and premature aging.
Choose a sunscreen with a sun protection factor (SPF) of 30 or higher. The SPF number is the level of protection the sunscreen provides against UVB rays. Higher SPF numbers do mean more protection, but the higher you go, the smaller the difference becomes. SPF 15 sunscreens filter out about 93% of UVB rays, while SPF 30 sunscreens filter out about 97%; SPF 50 sunscreens filter about 98%, and SPF 100 filter about 99%. No sunscreen protects you completely.
“Water resistant” does not mean “waterproof.” No sunscreens are waterproof or “sweatproof,” and manufacturers are not allowed to claim that they are. If a product’s front label makes claims of being water resistant, it must specify whether it lasts for 40 minutes or 80 minutes while swimming or sweating. For best results, reapply sunscreen at least every 2 hours and even more often if you are swimming or sweating. Sunscreen usually rubs off when you towel yourself dry, so you will need to put more on.
