I was getting brown spots on my back. i found that they would be reduced by putting tea tree balm on them too. but they would come back after i stopped putting the stuff on, plus i was getting new spots weekly. I paniced and stopped eating all manor of junk food and lifeless food. i found that if i stopped drinking coffee they disappeared altogether(especially that instant coffee). I think skin health is all related to liver contamination and of the body chemistry. Try the Liver Cleansing diet by Dr. Sandra Cabot(use search engine).
