Eczema Treatment Care

Hello everyone,
I have these rashes along the inner thighs of my body. I recently got diagnosed with atopic dermatitis/eczema by my doctor. He prescribed be a special cream to ease the outbreak. I have been using it for 2 weeks, but it does not seem to make these rashes go away. However, I know that eczema/atopic dermatitis is not curable but treatable. I was wondering what I can do to help prevent and make these rashes go away. I am a very clean person, am not very allergic to many things, and take care of my body well.
