Dear Ask Alison,
I was wondering what the current SPF guidelines are? I heard the new minimum is 50? Thanks!

Some other things to remember:
- Sunscreens last the same amount of time, regardless of the number. A higher SPF does not mean it will last longer.
- Reapply once every two hours you are outside, and more often if you are in water or being active.
- Check the expiration date: it should be less than 3 years old, and exposure to high temps may decrease its shelf life. You can compare sunscreens using the Library’s subscription to Consumer Reports
- Avoid the sun or find shade during high exposure times. Read more about UV Index Scale from the EPA)
- Channel your inner movie star! Remember that clothing, hats, and sunglasses can offer some protection from UV rays.
