I used to have horribly chapped lips, and now my lips are what gets me compliments the most, so maybe I can chime in here. The best lip balm I have ever used (and swear by) is by Organic 101. Most lip balms have 5-7 ingredients and usually focus on just getting rid of the symptoms for a little while, but Organic 101's has 15 USDA certified active ingredients and heals lips fast; its actually uncanny. I cannot recommend them enough.
.
They offer a 30 day money back guarantee on their products, even on their lip balms. I thought that was funny at first, but damn if they are that hardcore about a lip balm then they probably know what they are doing and convinced me to buy... glad i did. Anyways.. if interested check them out: https://www.amazon.com/Healthier-ORGANIC-101-Eucalyptus-Certified/dp/B076WGV2ZH/ref=sr_1_4_a_it?ie=UTF8&qid=1512344222&sr=8-4&keywords=natural+lip+balm
