I trust it may be genetic.If so no cure. Perhaps it is not genetic and there is a cure.I was told that normal skin regerates in 28 days. But in the case of eczema it regenerates in 4 days.Therefore this disorder of the skin.
It could simply be a fungal infection. Try using a broad spectrum anti fungal for a week or two, and make sure you dry your skin thoroughly. If it's not too painful, use methylated spirits to make sure they're properly dry.
