Please recommend a lip balm to prevent dry lips.

I am an office worker.
Professionally, I speak a lot and often stand in front of others.
So, I get nervous from time to time and live my life like that.
Could that be the cause?
My lips are dry, flaky, and sometimes cracked.
What products would be good for lips like this that keep them moisturized for a long time?
I think lip balm would be good.
