I want to start looking after my skin more... I have mainly dry skin, large pores dark circles under my eyes and some wrinkles with a deep set wrinkle between my eyebrows which can now be seen even when I'm not frowning! 
I'm early thirties. I use exfoliator a couple of times a week along with an electric face brush and wash my face daily. I use a basic moisturiser daily. I subscribe to glossy box so use lotions and potions as and when. I was looking at getting estee lauders advanced night repair serum but it pains me to spend so much on just one item. Anyone have any advice on what products I should use?
