Mouth corner cuts

Patient: Hello,I have small cuts at the corners of my mouth. They are not bleeding but do hurt and sting. Ive used antiseptics and neosporin. Now i am using antiseptics, hydrocortisone, and vaseline. Condition improved briefly for 3days than re-accured when i used listerine mouthwash.I initially got these cuts from biting into shelled peanuts. I believe the salted shell aggravated my skin. Now the cuts will not close. Infected?Any advice is appreciated.
