We had been using charlies soap for a month or so when dd got a blistering rash we could not clear up!! Went to the doc and everything.He even tested for herpes!! I switched back to our normal det we had been using for years and used the creams he suggested and I now know my gut was right it was something to do with the dipes.I just thought after a month and a half of use why would she suddenly have a reaction?? I went through foods she had eaten and everything.I hope they figure it out because the detergent worked great otherwise!!
