Thank you for your query.
As there has been no improvement following the change of soap and lotion I suggest you consult a dermatologist
. Without having a look at the patches it shall not be possible for me to comment. In case photographs could be uploaded I could have tried to help you.
I hope I have responded to your query to your satisfaction. Feel free to revert back in case you want to share more information.
Wishing your daughter all the best.
