How do you take care of your lips?

I'm the kind of person whose bad condition shows right from my lips.

For example, getting gum disease, or the corners of the lips cracking... or getting canker sores or chapped lips...

If anyone knows of any good products, please leave lots of comments...

For reference, my lips tend to be quite dry and flaky, so the lip color doesn't come out as well as I imagined, which is upsetting for me... ㅠㅠ
