It's not news to us that sun exposure ages the skin, but [Link Removed]  shows just how quickly this damage happens: just two days. Researchers from the University of Michigan exposed volunteers to the equivalent of two hours of sunlight over a period of two days and discovered in that short span of time, UVA1 rays (measuring 340-400 nm) caused darkening of the skin as well as produced molecules that break down collagen.  This process can cause skin to show premature signs of aging, such as sagging, wrinkles and dullness of complexion.

The UV rays that concern us can be divided into UVA (for Aging) and UVB (for Burning) rays.  Although the majority of sunscreens are formulated and SPF-labelled to protect us against burning, many do not contain effective active ingredients to shield us against the UVA rays that are almost 20 times more abundant than UVB rays.  We are exposed to UVA rays any time there is light outside.  From sun-up to sun-down, on clear days as well as cloudy days, UVA rays penetrate deeply into the layers of our skin and lead to age spots, sagging, wrinkles and some forms of cancer.  The bottom line, according to researchers, is that effective sunscreens should be used daily.

To ensure the most comprehensive, broad-spectrum protection against both UVA and UVB rays, select a photostable formulation with a combination of active ingredients.  Look for:
•Titanium Dioxide : blocks UVB rays
•Zinc Oxide : blocks both UVB and UVA rays measuring 300-400 nm. Zinc oxide is one of the few full UV spectrum sun blockers. Look for it if you are concerned about applying a chemical sunscreen. We like [Link Removed]
•Mexoryl SX: may also be listed as Terephthalylidene Dicamphor Sulfonic Acid; blocks UVA rays measuring 290-400 nm.
•Mexoryl XL: may also be listed as Drometrizole Trisiloxane; blocks UVA-II rays
•Avobenzone: blocks UVA-I rays; should be stabilized with Octocrylene
•Tinosorb S: blocks UVB and UVA rays measuring 280 nm to 400 nm
