Vitamin C skin care?

Question

I took a biology class and I learned that Vitamin C is water soluble.

So, it cannot cross cell membrane, which means you can't just apply it on skin because it wont work.

And there are so many vitamin C skin care, since it cant cross the cell membrane, doesn't it mean it wont work??

and why do stores still selling it?

Answer 1

You're right.  You benefit from taking Vitamin C when you take it internally and it's metabolised.

As for skincare products, most of it's to do with marketing.  You're an astute buyer but there aren't many of you.

From 8 years in pharmacy, the health of your skin is mainly determined by your genes (good skin seems to run in families) and other such things as the amount of collagen in your skin (again, to do with genes), hydration (keeping up your fluids), and limited sun exposure (sorry, surfers, but you don't usually have to-die-for skin!).

People will believe anything without having the real facts
