Toothbrush, then chapstick. it's sooo easy and it really works! Also if you want to plump up your lips and make them nice and healthy, rub a few drops of clove oil on with your fingertips (you can do lip balm underneath if you want). It tingles and sometimes hurts like hell at first, but it makes your lips look amazing.
Clove oil should help with your wrinkly lips as well.
