Chemical vs. Physical Suncreens
Here's one for ya!
ANYWAYS... Sunscreen works in one of two ways: Chemical sunscreens are filters. They reduce the amount of destructive UV radiation that gets through to your skin. Chemical sunscreens generally contain chemicals (duh!) that absorb both UVB (remember B = Burning) and UVA (remember A = aging) radiation.
On the other hand, physical sunscreens are sunblocks. As suggested by the name, they provide a physical barrier from UVA and UVB light.
Quick & Dirty BENEFITS of using Sunscreen:
By using a "broad-spectrum" (UVA and UVB blocking) sunscreen daily, you can protect your skin from sun damage and premature aging a.k.a. wrinkles, age spots, and the dreaded leather-like texture that is all too common! There is even evidence that regular use of sunscreen might help repair damage. Awesome!
I have always said to use a daily moisturizer with an SPF (sun protection factor) of AT LEAST 15. However, The American Academy of Dermatology says to select a sunscreen with an SPF of 30 or higher. You should also pick a physical block - look on the label for ingredients like zinc oxide and/or titanium dioxide. However, whether you choose a cream or lotion - or even an oil-free product - is a matter of personal preference!

I hope this clears the air a bit!
