Love the soap
Scent: Oatmeal & Honey
I bought this soap for my dry winter skin. It feels good and doesn't dry me out. I use a washcloth to apply it, as it dissolves quickly. I think the price is a bit high, but it's worth it for the results. I'll buy it again.

Heals skin
It definitely dries out your skin quickly but I do recommend moisture so the skin won’t crack or you get open cuts as your dermatitis is healing. I have dermatitis really bad where my skin drys and hurts when I have a cut, So far it’s working as intended.
