Something on my lip??

Hello!! Ive been dealing with the corners of my mouth being super dry (nothing hurting or burning just dray skin around the corners of my mouth) then i started feeling like a dry patch on my lower lip! Its a bit raised but it doesnt itch, burn, and honestly doesnt look supppperr red. What could this be? Ive also been getting some type of eczema on my eyelids/under my eyes. Im waiting in a derm appointment but wanted to see what you guys had to say. Also i am 21!
