I had seborrheic dermatitis on my chin and around my nose. I tried to clear it up with coconut oil but that ended up spreading it around my eyes. Raw apple cider vinegar diluted with water helped some, but I had to keep applying it daily.
Sea salt diluted with water cleared my SD up almost immediately and the effect has been lasting. I either add a half teaspoon to a pint of warm water and splash it on my fave or I put some onto my fingertips and gently rub it on my face while showering.
Since SD is related to oil glands, it makes sense that oil made it worse and salt cleared it up.
