This condition may have many sources like…. genetic predisposition, dermatitis and allergic reactions, or result from prescription medications…so the following is merely a suggestion for you to get some relief from the condition….see a medical professional if necessary.
With regard to dry hands, here are a few things you can try:
1. Exfoliate the dry skin with a 3% salicylic acid solution (usually drug stores have this in the hair treatment section as it is good for treating dry and itchy scalp conditions). Do not use any stronger solution…salicylic acid is anti-inflammatory (it is derived from acetyl salicylic acid which is better known as aspirin) so you should not have any adverse reaction to using it on your hands for about 5 minutes each night…however, if any adverse reaction arises then discontinue use of it.
2. Help your skin heal by applying petrolatum/vaseline on the skin at night and covering your hands with gloves to prevent the vaseline from being smeared all over your bed linen.
3. Use a rich shea butter based moisturizer during the day.
