Great for eczema
Size: 8.4 Fl Oz (Pack of 1)
Love this stuff. The only soap kiddo can use that doesnt dry out her eczema. Highly recommend. Smells nice, foams up, keeps her hands moisturized.

Worked well. Try it.
Size: 8.4 Fl Oz (Pack of 1)
This stuff did help my dry hands. I still struggle with dry hands a bit but compared to softsoap it is much better. Expensive but worth it and cheaper than going to the dermatologist.

Made my Hands Extremely Dehydrated and caused a bad Eczema flare up.
Size: 8.4 Fl Oz (Pack of 1)
I tried so hard to like this Hand Soap and used it for about a month, and I thought it was working at first, but I ended up finding out that it was actually making my hands drier and was making them crack more, as well as flaring up my eczema X10. The soap does clean, but it definitely strips any moisture from the top of your hands and the palms. It made my skin super rough. I was even lotioning up after, and the dryness was still very prominent. As for the scent, I felt that it had almost no scent. My fiance, who didn't have any issues with dryness or eczema on his hands, developed very dry skin due to this hand soap, and we found out 100% that it was this hand soap once we switched to another. I know it has worked for some, but I personally wouldn't recommend it, and I don't think it is worth the price.
