For me chapstick is addictive, you have to keep using it or the chapped lips come right back. I use Vicks Vaporub, it heals chapped lips and isn't addictive (if addictive is the right word).
I make my own. 1 part bees wax to 3 parts olive or avocado oil melted together on the stove. I bought a few hundred refillable tubes on amazon for $15 and a lb of bees wax about two years ago and that should be enough to last me 10 years or so at the rate my family goes through it. By then I hope to be producing my own bees wax and sunflower oil on site.
