I've never been to either of those stores, but I'd try if I were you. If they don't have that they may have something similar. It's the Borage oil that is the key ingredient.
If you go to the pedi they will prescribe a steroid cream. I used it with ds for a few weeks, the exzema kept coming back. Plus I read some bad things about using steroid cream long term. So that's when I found this stuff and it works every time and is all natural.
