My skin used to be very dry too, i have found since using the vit c serum here on the site it has stopped my skin becoming so dry, mainly as i think it has helped exfoliate away all the dead skin cells, that were not being removed from my skin before!
Also buying a micro fibre cloth once a week will really help!
I dont spend any money on branded products such as clinique, buying things such as shea butter off uk whole salers online that i mix in with coconut oil and aloe vera etc i really like using on my skin too!
Vitamin e is really good for the skin, i have heard jason e vitmain e serum is meant to be very good too!
Always use a good sunscreen too, even in the winter here in the uk!
Also if your looking into diet things like drinking water will really help 2 litres a day is fine for a women to drink! Green Tea is also good, antioxdients with omegas, (even if you take these in supplement form) are all really good for the skin and antiaging too!
