Cor by Plank — World's Most Expensive Soap


Why so costly?

Simple: silver nanoparticles are the not-so-secret, über-pricey active ingredient.

From the website:

    Cor Soap by Plank

    "Blimey your skin looks fab" will be what your friends say when you start to use Cor soap.

    Lasts anywhere from 6-9 months when used with discretion.

    Cor is suitable for every skin type.

    Cor's mild pH level of 7.2 means it's just as effective on troubled acne skin as it is on the most delicate and sensitive of skin.

    • 120g (4.3 oz)

    • Ingredients: Silver, Silica, Collagen, Chitosan and Sericin.



$115 a bar.


I just had the crack research team (mathematics section) run the numbers; they tell me that comes out to $428 a pound.

A bit rich for your blood?

Perhaps mademoiselle would like to try a sample bar?

No problema.

I was wondering if anyone who has rosacea has tried this soap?

Actually, I've tried pretty well everything. Proactiv was fine, but stopped working for me after awhile, and subsequent (incredibly expensive) lines of product were marginally effective @ best. Cor soap has pretty well solved all my facial skin problems, so (having actually made use of it) I wouldn't even think of comparing it to the "zillion antibacterial soaps out there" that seem just about as effective as a splash of water.

I would be astounded if rubbing any amount of silver on your skin caused argyria, no matter how small the particles were.

I would also, however, be astounded to discover that this soap did anything that ordinary "moisturising" soap or body-wash didn't.

Perhaps the silver's meant to be there to kill germs, or something; metallic silver _does_ do that, which is why people decide to drink the darn stuff and discover for their own stupid selves the difference between an antiseptic and an antibiotic.

But if that's all the silver in the soap has going for it, there are of course about a zillion antibacterial soaps out there that do the same thing for 1% or less of the price.

OMG!! Skipweasel, this is a terrible story. So many things in this world that can and do happen to a person. Dr. Joe, as a doctor, have you ever seen anyone with this condition after having argyria ?

Argyria, anyone?

If they really are nanoparticles, it's quite possible they can find their way into your body through the skin.
