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.

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.
