hello dear...
i have suffered from severe eczema my whole life and this pregnancy is making it flair up... here is some pointers:
1. every time you shower, use *WARM* not *HOT* water (should be doing this anyway since youre preggo)
2. as SOON as you get out, before u even dry off, use some Cetaphil Lotion (you can get it at a drug store for like $10 a tub), then gently pat your skin dry (dont rub too hard, will further aggravate your eczema)
3. after you dry off, put some more on
4. lather up until you look ridiculous before you go to sleep! it doesn't matter how ridiculous you look! this way you will not scratch throughout the night and your skin will still be moisturized when you wake up in the morning.
5. as soon as u wake up, put more lotion on!
for moderate flair ups use Cetaphil (non steroid, non prescription, perfectly safe for pregnancy)
for a more sever flair up, use it's counterpart Aquaphor (also non steroidal and non prescription, can purchase at a drug store)
