Yes, retinol rocks.
But I'm more interested in what ascorbic acid you use. Vit C products (Perricone, Lancome) really make a huge difference in my skin but I'm tired of paying a premium for it.
I read that the vit C needs to be in a certain form, like really small molecules, in order to absorb. I put some Vit C powder in a cream and it just felt grainy.
So, what are you using? Inquiring minds want to know! ;-)
