For several years, the skin on my hands periodically becomes degradated: the back of the palm gets very dry, the side of the fingers becomes irritated/red, and I get skin cracks on either side of the nails, on all fingers. I used to think this was due to some combination of cold weather and stress, but I'm beginning to doubt that. This conditions backs off when I apply skin moisturiser, but it keeps coming back regularly. Is this cause for concern? In the worst case scenario, something like this could indicate Bowen's disease, HPV or actinic keratosis - although casual questioning of a dermatologist friend some time ago suggested this to be unlikely.
I wasn't able to attach my photos here, so I've uploaded them on a free image hosting website in case anyone has time to have a look and suggest an answer. Thanks in advance!
