The EPA claims that we will reach peak ozone-layer depletion levels by 2010. After that, the ozone layer should start to heal and we can all go back to worrying about climate change instead. In the meantime, we need to find a healthy sunscreen that works.
Using sunscreen reduces your risk of squamous-cell carcinoma, melanoma and other forms of skin cancer. Many sunscreens make crazy claims about their products, but these claims don't really hold much water.
What to Watch Out For In a Sunscreen
High SPF Numbers
SPF 50 sunscreens provide only 1.3% more protection from UVB than SPF 30. It is more important to apply liberally than it is to use a crazy-high SPF.
Waterproof
Sunscreen vs. The Universal Solvent? Water > Sunscreen. Some resist water, none are waterproof.
All-Day Protection
Sunscreen can last all day, if you remain motionless without sweating. But you are bound to sweat and probably move around some. I'd believe my skin over claims on a bottle.
Blocks All Harmful Rays
Nope. No sunscreen can do this.
Chemical-Free
Is anything actually chemical free? Zinc oxide and titanium dioxide are chemicals by Mendeleev's and most people's reckoning.

What to Look for in a Sunscreen
Kim Painter of USA Today gives a few helpful tips on what to look for in a sunscreen.
Look for sunscreens that say "broad spectrum" on the label, and check for these ingredients: Avobenzone, oxybenzone, titanium dioxide, zinc oxide or ecamsule (also known as Mexoryl SX)
Painter also goes on to say that sunscreen, as well as it may work, does not make the wearer invulnerable. It is important to limit your time in the sun even if you do use sunscreen.
