Sorry for the very detailed title, but it is basically what I need:). I tried several serums, selected randomly, and never been super impressed. Basically I don't really see any difference other than some oil control for some of them!
Then I read here that I should go for a minimum of 20% of Vitamin C in the serum. Fair enough. But there are soooo many options out there, in so many prices, and on top of that the majority of the bottles don't even say how much Vitamin C they have..... I feel very lost....
My budget is £20 top, but the cheaper the better of course. Does anyone know a serum that matches the requirements? Many thanks!
