Does the skin only thin on the area the cream is put on or would it affect areas nearby?  The part where I see the veins is actually not the part that I put the cream on at all, but is next to it, however none gets on this area.  Would the cream cause the skin nearby to thin, or only the skin where the cream is directly applied?  If only the skin that the cream is directly applied onto, then I must just be worrying too much.

I have never seen the veins look this way before though, so perhaps I should discontinue use of the cream and see the derm to see what he says about it.

I have only noticed it where I put the cream inbetween my toes, having said that it does look a slightly bigger area than where I apply it. However this could be because as I walk the cream gets squished around and spreads to areas I didn't put it.

But I think you have answered your own question when you said "I should discontinue use of the cream and see the derm to see what he says about it"

You are obviously and "rightly so" concerned about using such a treatment in a delicate are. There are other creams you could try and personally I would prefer one that doesn't thin the skin. So yes, go and tell your dermatologist you are not happy and want to try something else.
