Tommy, I looked into Prep H a few weeks ago, when someone else

brought it to our attention. There may be something to 's

distinction between US and Canadian versions for use under the eyes,

but I came to the same conclusion as you did, that the two countries'

different formulations should not, theoretically, affect its

presumptive effect on redness/flushing.

The US version contains a vasoconstrictor (phenylephredrine? I don't

recall at the moment, but it was the same ingredient and

concentration found in local anesthetics -- although those are

injected directly into the tissue, not applied topically).

A hemorrhoid is an exposed dilated vein, unlike the dilated vessels

in rosacea which reside unexposed in the dermis. I don't know that

veins can actively dilate and restrict like arteries can, so I'm not

certain what a vasoconstrictor is doing in Prep H. Mucous membranes

have a different skin structure than does the face, so a

vasoconstrictor may have a function. I don't know, I've only

prescribed witch hazel (Tucks) or Prep H w/cortizone for hemorrhoids.

Whatever, on the face, I wouldn't think a topical vasoconstrictor

could transverse the entire epidermis down to the dermis in

sufficient concentration to cause consistent vasoconstriction across

the entire face. But I really don't know.

I'm trying to think of a quip on this asspiring topic that will get

past the moderators, but I can't think of any. (Oops, did I just make

a typo? )

I assume you will further buttress your argument by rectumfying

your mis-spelling?
