Smells wonderful
I purchased this for my granddaughter. She has eczema on her upper arms. It smells great and lathers up very quickly. It does moisturize the skin too. I will update once we see if it takes care of her eczema. Definitely would buy again.

Effective & Great Value!
I’m a connoisseur of soaps - liquid - solid - fragrant decadent soaps - not so fragrant soaps - but I was searching for a soap to soothe my hands from a lot of handwashing over the years & autoimmune issues.I chose this soap based on reviews & was not disappointed. It delivers what the description states.Calms down the itching & dryness. Effective Product This soap fits my criteria- a good sized bar - lathers softly- quite moisturizing- glides over my hands - smells so good - a little spicy smell - reasonably priced- also very good for my body - I ordered another bar for good measure!

Good and effective
While waiting for my appointment with the doctor, I decided to give it a try, and it helped me a lot in controlling a minor allergic reaction I had on my skin.

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.
