DURING THIS WINTER SKIN PROBLEMS WERE PRESENT SO I TRIED THIS ITEM, AT FIRST I NOTICED THAT IT MADE MY SKIN FEEL REALLY DRY BUT IT DID CALM MY SKIN DOWN TO THE POINT WHERE THE ISSUES, WHICH WERE BECOMING INTENSE, JUST DISAPPEARED AFTER I USED IT 2-3 TIMES EVEN ON MY FACE, SO PERHAPS DRYNESS IS WHAT ENDED MY SKIN ISSUES (PSORIASIS) I HAVE EXPERIENCED IN THE PAST USING OILS AND CREAMS WHICH HAVE MADE MY ISSUES WORSE SOOOOOO THIS ITEM WAS A SUCCESS FOR ME.

Fantastic soap for the dermatitis and eczema prone

You guyyyyysss, my hands have no dry, itchy spots right now. None. This is remarkable because before now I have for years had issues with eczema/contact dermatitis patches that have at times (aka: most times) been pretty unbearable. To say that I’m overjoyed to have found a natural soap that truly works for me is an understatement. When you use this, you can feel that it’s moisturizing your skin. It’s fantastic. If you haven’t tried it, do yourself a favor and get yourself a bar. I’m wondering now if I can use it on my entire body and to wash my hair. That’s probably a little overboard, but it’s that good and now that I’ve used it I suspect all my skin problems are contact dermatitis that could be solved by the right soap/shampoo.
