Hello, My Bottom Lip Has Been Consistently Dry And Wrinkled

Hello, my bottom lip has been consistently dry and wrinkled for 8 months now. I have tried several lip balms (currently aquaphor) and am taking vitamin B-12 and have yet to have success in recovery. I can attribute the root cause to licking my lips subconsciously , and the occasional moments I enter a walk in freezer.

Since I noticed the condition, I have made an effort to keep my lips (specifically my bottom lip) moisturized as my top lip is normal. The dry area on my bottom lip stretches all the way across the center contact point with my top lip.

I have not seen a specialist yet, but my concern is if this is symptomatic of a more serious health condition. Any treatment advice or recommendations would be greatly appreciated.
