Diagnose my rash pls?

Hey everyone! I've had this persistent rash under my lips, on my chin, for about two years now. I've tried ketoconazole, tretinoin, and several other creams I can't even remember. I've seen a few dermatologists, and each prescribed something different, but nothing seems to work. The rash just won't go away and it hasn’t been great for my self-esteem. I'm thinking about trying a chemical peel to help with the appearance, but I'm not sure what the best course of action is. I know the picture is blurry but any advice?
