Here's my two cents...
Of course you're adequately hydrating... I know that because you're in the BROWN ARMY and you've gotten the memos, so I won't mention drinking 120% of the recommended daily H2O ration...
I have psoriasis, which in my case doesn't affect my hands very much, but it does make me well-versed on the topic of moisturization.
First, drink way more water than you want to (sorry couldn't resist).
There are creams, salves, lotions, oils, etc...
It's taken years of cardboard abuse to lead to your present situation, but you don't need to suffer needlessly.
If you don't wear gloves while you are working, you might try it out (I wear this brand of gloves: '
MAGID ROC10T-L', thin enough to work the DIAD, etc.). If you really can't stand wearing gloves, suck it up for two weeks and lube up your hands before you put the gloves on (with salve or oils).
Cardboard boxes suck serious moisture from your hands.
As far as the emollients go, sesame and olive oils are awesome, but they make your hands smell like food. Jojoba oil is a better pick as it doesn't smell like food and works just as well, although it tends to be a bit more pricey.
As with anything else in this life, consistency is key...pick a routine that works for your lifestyle and your hand-therapy regimen and stick with it, whether it's '
wearing-moisture-filled-gloves-at-night', or '
wearing-moisture-filled-gloves-during-work', etc.
Personally, I can't wear gloves at night whilst sleeping. At all. Can't do it.
Cheers.
