Oh, skincare ingredients; I've tried so many, each claiming to be "it".  It seems like a new holy grail ingredient comes out once a month promising me young, smooth skin sans age spots, lines, blemishes, or wrinkles. So, I bite: I try it, slather it on my face, say a prayer and.....nothing.  So, I decided I would go back to what's worked for me previously: good old fashioned Vitamin C.  It may not be a new ingredient, but there's a reason it's been around so long: it simply works.  Whether you're a long time Vitamin C devotee, or fairly new to this ingredient, I've rounded up the top 7 ways including Vitamin C into your skincare routine will benefit you.
