@fify-- I know what you mean. I have dry and sensitive skin too. I do use a Dead Sea body salt scrub but only for my feet. It doesn't irritate my feet at all since that skin is much rougher.
Plus, I have diabetes and my circulation is really bad, especially in winter. My feet turn white and purple sometimes from the cold! So I like doing a nice hot foot soak followed by a scrub with this sea salt scrub. My feet turn a healthy red and feel so good.
