When you go outside to enjoy the warmth and sunshine, you've got to protect your lips from the sun's harmful rays. That skin can get sunburned too, and excessive exposure could cause lip cancer.
Just as you apply sunscreen to your skin, you need to apply sunscreen to your lips. Many lipsticks, lip glosses, and lip balms contain SPF, so check those labels ladies.
Here's a list of some of my favorite protective lip balms and lipsticks. Beeswax lip balm from Burt's Bees is still my all time favorite even though it doesn't contain any SPF, so I just reserve it for nighttime use if my lips feel dry after spending a day in the sun.
