. . . and how do we know his name is really Kevin?
I won't put anything on my face that I can't at least see the list of ingredients for first.
That answer is pure hooey. For all we know Kevin and his Appalachian cousins/sisters have lye burns from using the family recipe.
The "family recipe" comment is such a cop-out.
This is a grand place to point to the vendor TOU here at the B&B-
and this in particular,
"Vendors should expect in-depth, specific questions about their products and be prepared to discuss manufacturing process and ingredients."
Personally when it comes to Old Family Recipes and soap my opinion isn't very high of them because they lack modern technology to understanding the ingredients and the oils to get a really good bar of soap.
Maybe it's just because I tried some soap that a friend of mine makes (and sells) using an old recipe of his aunts. His aunt is 89 and he refuses to change his recipe because it was his aunts recipe and he feels that she is right and that is the only way to make soap. Granted it was a hard bar of soap, but it was also over-cleansing and stripped to much of the natural oils off the skin. It left my skin feeling way to "squeeky clean" and dry and almost itchy because it didn't moisturize the skin at all. To me that wasn't a good bar of soap at all because it lacked the knowledge that we know about how to make soap and the properties of oils. So I would personally opt to buy or use a product that has science on it's side. At least for configuring the recipe knowing it's going to be a gentle soap, not harsh and will leave me feeling clean but not to squeeky clean and moisturized skin.
