Hi there!
In looking at the pictures you have submitted of Nixon's lips It looks like he could have a mild skin infection called lipfold dermatitis. This can be either bacterial or yeast. And it does appear to be mild.
Other possibilities would be irritation from his canine tooth rubbing or maybe auto immune conditions.

Since it does appear mild you can try once daily topical cleaning of the areas with over-the-counter astringent pads. Those type of pads that the store sells for acne.
If you don't see any improvement within a week or if it is getting worse I would recommend you take Nixon in to see his vet. They will be able to closely examine him to make sure it isn't something more serious and if they do think it is an infection they can prescribe medication for him.

I hope you found this information helpful.
I wish you and Nixon all the best!
