On the Uk shopping site link provided by Calmvoice, it says this about Bariederm:
It costs about $8 US (5 pounds
"BARIEDERM Balm contains :
■It's the association of two polymers that form an isolating barrier on lips to prevent the future damage. It also allows the lips regeneration in depth to regain comfortable lips. Finally, it soothes the tightness and tingling sensations.
■Phytosqualanes, Phytosterols and Lipophilic Base
Lips are fragile and are often prone to drying and cracking because they are constantly in the open air and is the area where the protective cells are lowest. BARIEDERM Balm provides you not only a protection against climatic aggressions but also effectively repairs and soothes damages suffered by lips."
To me, it sounds like the polymer isolating barrier (and those polymer chemicals they use are some pretty interesting ones with a lot of industrial uses - see my reply to Ronin above) is the main thing in this product, plus some vegetable oils and vitamin E.
I don't really see how this could be a magic cure for the stubborn cheilitis that many of this forum's users have. Sure, if you've got a passing case of chapped lips, use a plastic/polymer lip salve for a couple of weeks.
But maybe it will work - maybe some folks from the UK contingent on here will try it at a 5 pound pop.
I only searched on it for a little while on the internet earlier tonight, but I found it strange that I couldn't find any doctors recommending it, no consumer websites recommending it, no medical tests mentioning it. If it's an over-the-counter product, not expensive, and not talked about (except by one new forum member), but yet it has been on the market for a while, I have my doubts that it's something that is amazingly effective against treatment-resistant cheilitis.
However, I am very open to being proved wrong about it, and I hope that it works for some people!!
(I personally don't like the sound of the polymer chemicals, and olive oil as a lip treatment on its own irritates my lips and makes them exfoliate more, so I wouldn't want to use a salve with olive oil in it.)
