I know you were kidding, but I think there would be enough moisture in a dry suit to still be a problem--trench foot is just from continued damp sock exposure, and for folks with hand issues, you'd need to keep hands dry. Oddly, I've only had it on my hands once. It's usually just feet. From my reading of general blogs, people's skin issues varies. I have eczema, but my husband's skin is "normal to slightly oily." So little published about it, hard to say...
