Will order again!
This soap worked wonders for my psoriasis. It was very gentle on my skin. The bars lasted a long time which I feel like made it worth the money. The ingredients being all natural is also a plus for this product. While it didn't make my psoriasis flaw-up go away it did help with the itchiness of the areas. And it just soothe my skin.

Great product.
I bought this as a Christmas gift for my son who has eczema. He told me that he uses it daily and have had no issues and been eczema free since.

This soap smells really good. My son uses this soap for his eczema.
I like the fact, that the soap bars are big. I was able, to cut it in half. But, it does come with 2 bars. And it smells really nice.
