You have them too. They're the flappy things that keep moving and get you thrown in the dog house.
They dry out, crack and are probably going to keep you in that dog house longer.
Make them happy with our 15g, SPF 15 lip protector. Think of it as the hulk standing guard over your mouth.
It's got a matte finish, so nobody will even know you're wearing it. Hemp seed oil, beeswax and shea butter to keep those flappers painlessly flapping.
