The first thing you need to do is buy some Vaseline. I got the travel sized one because you will not need that much, so no need to buy a huge tub of Vaseline.
Next put Vaseline on your lips over night. So right before you go to sleep, apply a layer of Vaseline and sleep with it on.
I do this every night but it really depends on how much you need to. Now enjoy your soft, better-looking lips! 😉
