The percentage doesn't change with quantity used- like sunscreen. If you slather on one layer of SPF15 or two, it's still SPF15.

Can this be used with eye cream?
I wasn't sure if I should use it around my eyes

on CosMedix Pure C
I wouldn't. I don't know that it would be a problem but it can tingle a bit so I haven't had it around my eyes.

what is the % of vitamin C
The previous "answer" didn't answer the question - different products (mostly serums) have varying % (amount of concentrate) of C, e.g. 5%, 20% (see Obagi as an example)...it's not clear what the amount is in this product. Can someone who actually 1) read & understood the question, and 2) has an informed answer....like a Cosmedix aesthetician.... answer??
