I agree...if the naturopath is not experienced in dealing with skin issues specifically, then they will just go through probable issues (e.g. candida) and hope that that is your issue.
I also don't like it when they recommend too many supplements...keep in mind that many naturopaths actually receive commission and/or discounts from specific stores (one naturopath I went in Europe to refers all his customers to a specific pharmacy/health store to increase supplement sales).
I think the conservative approach is to just start with a few supplements, plus diet changes, and see if there is improvement. No need to take more than you need.
