treat your lips the same way you would treat the rest of the skin on your face! put a small amount of moisturizer on em after washing. i like to use something super gentle like an eye cream but whatever you have on hand will work.
THEN, before you go out, apply the lip balm of your choice. the balm is meant to be a protective layer between your skin and the dry air. if you put lip balm on top of already dry lips it's pretty much useless bc the skin can't absorb it, which sometimes makes the problem worse.
ok stay soft
