I also have used Aptimel 1, 2 and now 3.
DS also has a bit eczema and he had a particulary bad patch on his face I needed antibiotics for. He also used to really scratch his head and face, to the extend of taking out chunks.
I have to say that he has stopped doing it now,however that could coincide with the change to Aptimel #3.
I never thought about linking the eczema with his formula
but does make sense.
There is no reason why you can't change milk, if your not sure about buying a full box of power, you can always try out a ready made carton, but they are pricey.
