To buy the best soaps always ask seller what the ingredients are.
E.g For skin conditions the best soaps to use are 100%pure coconut oil, goats milk, oat, honey soap.
The best soaps are 100% pure soaps.
The ones that are not pure, with mixtures of ingredients will not work on ur body or face as well.
From my experience 100 % pure coconut oil soap has done wonders for my family. Your skin will feel so soft and clean and is great for dermatitis and enzema etc.
Hope this helps :)
