you just have ezcema on your hands? use the steriods mild ones are ok.
what steps to you take to protect your hands?
what is your ezcema routine?
I suggest,
you are careful not to
handle raw meat, use fork or plastic disposable gloves .
never peel potatos unless under running water as starch irritates.
avoid handling tomatos, use inside of plastic bag in supermarket, or again use gloves when at home.
moisterize , every time your hands hit water. EVERY TIME. near every tap in your home your soap substitute and moisteriser should be near by.
gloves outside esp now in winter as cold air drys out skin.
use aquaous cream as soap.
remember shampoo and conditioner will irrirate your hands, so try and find a way to minimise the exposure on your hands, or change your washing routine or soaps/shampoo conditioner.
cotton gloves at night with steriod and moisterizer (not romantic or attractive, but work, i use cotton gloves from poundland!)
bear in mind that skin once made sensitive can take 6 months to settle down. so this will take some working and planning for.
This is the voice of hideious experience, with rpt skin infections from open skin. now under reasonable control, but does flare up at times.
good luck.
(if you had all over body ezcema then yes consider food an issue, or environmental allergies, but just hands, not gonna be the problem)
