Sounds like eczema, and in infants this is almost always due to an allergy. From your description of how the eczema is all over her body and doesn't go away, it sounds like there's something your daughter is exposed to everyday - it could be in the environment (a pet, or laundry detergent residue on her cloths, for example) or it could be something she's eating (either via the mom's breastmilk or via formula - cow's milk and soy are the 2 biggest culprits at this age).
If it's environmental, you can ditch fabric softeners all together, switch to a "Free & Clear" detergent and only use 1/2 the recommended amount to wash the clothes, and do an extra 1 or 2 rinse cycles to see if that helps. Since it's summer, you could even let her be naked to see if that helps clear up the eczema (if it's a contact allergy from something like laundry detergent or dryer sheets). If you have pets, it might be a little more challenging to get her into a "pet free" environment for a few weeks to see if her eczema goes away, but it'd be worth it.
However, I'd put my money on a food allergy/sensitivity. Below is a chart of common signs of food allergy:
The bottom line is that this eczema is a sign that something's not quite right, that she's having physical irritation/inflammation due to something she's around or eating -- and no cream, whether prescription or drugstore or Arbonne is going to solve that problem. The creams might lessen the *symptoms* of the problem, but the inflammation and irritation your daughter is having will still exist. It's really important to address the problem, to play detective until you figure out what's causing her eczema! If you put in the time to do this now, her health will be better overall (now and in the years to come!). You can do it, it does take a little effort on our parts as parents, but it's very worth it to have a baby who is not chronically irritated/inflamed (because if it's eczema on the outside, you can imagine that her insides are probably suffering a similar inflammation - no fun)!
Some links that are really helpful in starting this process:
1) Even if your baby is past a colicky stage, this short article by a pediatrician talks a lot about food allergy, what that looks like, how it's far more common than most peds know, etc.
2) Helpful for young babies who are still exclusively breast or bottlefed - even though the site is geared towards breastfeeding moms, the information on what a baby is sensitive to still applies (because it doesn't matter how they're getting a food allergen - whether by breastmilk or by formula - it will show up in the same/very similar way) http://www.kellymom.com/babyconcerns/food-sensitivity.html
3) A wonderful primer on food allergies - easy to read, excellent information, by a renowned pediatrician
It'w wonderful that you're being proactive about your sweet little girl's eczema - with some detective work on your end, you will very likely be able to identify the triggers/causes of your daughter's eczema problems, avoid them, and leave the creams behind. My son had an allergy to dairy and soy, and it was amazing how bad his skin got w/ just 1 or 2 exposures. And when his diet (or mine, as I was breastfeeding) was clean and free of dairy & soy, his skin was soft, smooth, creamy, and clear (and he slept a heck of a lot better too). :)
Hope you'll find some good info in the links I provided. Best of luck!
