There is only one absolute 100 percent effective way to prevent aging and that is dying young, you cannot even slow down time. So like she says, eat healthy, exercise, get enough sleep, stay out of the sun, and BE HAPPY.
Being miserable just makes it FEEL like you are living longer.

”Vitamin C works when you eat it, not when you slather it on your skin.”

This is contradicting with what is said in this article:

Can you explain this to me? I’m confused

Thanks so much for this very helpful string of questions and answers! I’m also a 20-something trying my best to be (and look!) healthy while juggling contradictory advice on the topic. How refreshing to find a solution that is simple – both to understand and to apply.

Alright, you're right there are some studies showing an improvement of skin treated with Vitamin C (eg. this one) when delivered from a silicone base. The Perricone product above is a water based product. There are studies like this one that show water-based vitamin C treatments don't have any effect. I'm intrigued by the Skinmedica. I'll have to do a bit more research. Thanks. Left Brain

there are many peer reviewed studies that show L-ascorbic acid at the proper pH (and only that particular form of vitamin C) is effective in preventing and repairing sundamage, which is a huge part of skin aging. So vitamin C applied topically is useful, although it has to be “L-ascorbic”, which, in water solutions is unstable and oxidizes quickly, but in, say, a silicone base, remains stable (skinmedica makes one with lots of research backing it)
