I was wondering if someone can compare the functionality of vitamin A, Bx (x means numbers, such as 1, 2, 3, ...), C, D, E, K in the skin? They are used in cosmetics but what is their actual effect?

If there is some source that compares between them in particular, I think it will help me understand some important basics.

Some products:

GNC Vitamin C Moisturizing Cream

GNC Vitamins E, A & D Moisturizing Cream

Reviva™ Labs Alpha Lipoic Acid Vitamin C Ester & DMAE Cream

Reviva™ Labs Vitamin K Cream

I added a section to your question to ask for the effect the vitamins have on skin in general separating it out from their presence in cosmetics. Feel free to re-edit if I've missed your point. –  Rory M Nov 24 '12 at 23:21
Bx and C are water-soluble so unless there are special uptake systems that I'm not aware of, they should have 0 effect if you rub them on the skin... –  Armatus Nov 24 '12 at 23:25
@Armatus: Perhaps I was not accurate enough. There are cosmetic products with ingredients of Bx and C derivatives. –  Tim Nov 25 '12 at 1:48
Yes, my guess was that using those vitamins would probably be purely for marketing purposes, not for any actual effect :) Except for hair products maybe, but your question is about skin. –  Armatus Nov 25 '12 at 13:12
I think this question is too broad to encompass all known vitamins. –  leonardo Dec 26 '12 at 22:49
