[|Human|] I have dry itchy and cracked skin on the tops of my big toes - symmetrical.  The same for my index fingers on both hands.  No other digits affected.  Steroid creams havent worked but anti wrinkle cream and heel crack creams seem to help somewhat.  Any idea to cause?  Im 45, female and not on any meds or weird diagnosis...yet!
[|AI|]  Hi thanks for writing here. The condition seems to be keratoderma. It can occur secondary to eczema, psoriasis,allergies to detergents, soaps etc. Avoid harsh soaps and detergents.  Apply moisturizer on daily basis which will keep your skin smooth. There is no use of steroids if you do not have itching.  You can use Whitfield ointment at night which is available over counters. Use socks and gloves on a regular basis.  Take care.
