History <a href="http://jeannehauser.com/stmap_41i0o4.html?levitra.myambutol.aspirin" rel="nofollow">ivermedi.com</a>  In June the U.S. Food and Drug Administration imposed new regulations on sunscreen labels to help consumers decipher which sunscreen is best for them. Under the new regulations, sunscreen manufacturers can no longer claim their product is "water-proof." Instead they can only claim sunscreen is "water-resistant" up to a certain time limit. Additionally sunscreens that claim to be broad-spectrum must block both dangerous UVA and UVB rays.
