Some members of the AtopicDermatitis.net community have said that bathing with apple cider vinegar has helped their skin. The National Eczema Association site has a piece about bathing which talks about adding the vinegar to bath water and soaking for 15 minutes (http://bit.ly/2zNkXrt).
While I have not heard any community members mention drinking apple cider vinegar yet, I am interested in hearing those experiences if anyone has tried it!
