Worth a try
Fast Delivery as described. I'm on my 3rd round of antibiotics for a skin rash due to a allergy to a medication. The soap and a microbial spray is helping with the itching and we expect it to continue. The redness is turning pink and is getting better. I like that it has natural ingredients. I think it works with in con. It's worth a try.

Very good product and I will buy it again.
I love this soap. I have contact dermatitis and have skin issues, I get little blisters that itch like crazy and if scratched turn into little sores. This soap is helping to clear up these sores and I do not itch at all. The lather is great and my skin does not feel dried out at all.

Gentle and effective
After using for 24 hours, my hands are no longer dry and chapped from the eczema. The soap has a pleasant smell and leaves my hands very soft. It also leaves a pleasant smell in the room it's in.
