hi. thanks for your time. about 3 months ago i started having this crusty stuff on my face, in the creases under my cheeks. it s easily picked off, but then the skin underneath is red. and the crusty stuff comes back. then it started under my nose. first started on one side of my face, then that went away, and it came back on the other side of my face, just in the creases under my cheeks when i smile. i ve tried oregano oil, teatree oil, but it continues to COME BACK!!!! what do you suppose it might be and what can i do about it? thanks SO much! Joy
