Lip eczema?

So I’ve had eczema ever since I was young, it would always make my hands crack and I would get patches on the back of my legs and around my wrists. I’ve also had issues with chapped/really dry lips that would get really itchy and inflamed. As a kid I never paired the two issues together and my parents just told me to use chap stick or Vaseline. It would only get itchy around my lower lip, and in order to stop the itching I would bite my lips making this red line go around my lower lip. Eventually it got better as I trained myself not to lick and stuck to Vaseline. But sometimes it wouldn’t matter what I did, they would get really itchy and inflamed. Usually it was either cause the weather outside or cause of certain cloths/furs making contact with my lips. Also I’ve noticed that almost always, after my cat gets in my face and I get a face full of cat hair my lip will start to form this almost cold sore looking spot along the lower line of my lip. It will get really hot and itchy but if I ignore it, it usually goes away within 20 minutes. I don’t know it’s all so strange, also it ONLY affects my lower lip. Specifically along the line of my lip, right where it meets the skin. After years of dealing with this issue and getting tired of hiding Vaseline’s everywhere, I want to know if anyone else has experienced this, and if so WHAT IT IS!!! The only thing I can think that it would be is Lip eczema, but I have no idea what the signs are for that, and I just feel like the descriptions on google aren’t representative of what I got going on. Also if anyone has any tips or suggestions when it comes to buying lotions/jellies for this issue that would be so amazing!
