Older sunscreens allowed people to stay out in the sun longer without burning but provided little protection against UVA, so they increased people's exposure to these wavelengths.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.newscientist.com/channel/health/mg19426101.500-sunbathers-beware-the-aray.html">If UVA really is responsible for melanoma, a whole generation may have been misled into thinking sunscreens allowed them to soak up the rays with impunity.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.newscientist.com/channel/health/mg19426101.500-sunbathers-beware-the-aray.html">Most newer sunscreens do now provide some protection against UVA, but there is no uniform standard for measuring this protection, so it's hard to know what you are buying. What's more, even the best modern sunscreens don't seem to provide enough protection against the harmful effects of UVA. </blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/4F8CB163-EED4-4870-B4A5-B16BEA88700A/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
