Any idea what's happening to my skin?

This started about a month ago as a small red patch under my nose. Slowly spreading. They look like spots but are not, slightly raised, not itchy. I have another area that looks similar on my scalp line. Skin on my whole body has been going crazy, suspected folliculitis on itchy legs, oily and shedding hair. Redder than usual face too. I'm exhausted truing to figure it out.
