Hello all
So, another new thing for me to look at - I am wanting to make an eye serum (I would say it's for The Admirable Lady, but I look like Uncle Fester a lot of the time!) and I want to add in Vit E and some caffeine.
From what I have found, Vit E is usually 1%. But is that the thinking from "y'all"? And about the same for caffeine?
As a heads up, I am looking at using guarana powder, which is about 12mg of caffeine per gram of powder.
Thanks for the help.
