Best foundation for dry skin????
I think that more importantly is what you are using before your foundation. I use a really great moisturizer from Philosophy. Try the Miracle Worker anti-aging kit, it also has a concentrate serum that is lovely. Not oily at all, absorbs well into skin. Perfectly soft skin. But Makeup Forever has great foundation, great color matches skin well. Good coverage as well. For spots use their Full Cover cream.
Sofie has a great suggestion, make sure your moisturizer is hydrating and doing its job! If you are in the need for a new foundation,try using one of my favorites here:
Laura Mercier Moisture Supreme Foundation
Dior Diorskin Nude Natural Glow Hydrating Makeup
If you really want something is an all in one, try a hydrating tinted moisturizer or even a BB cream which is a sort of primer, smoother and foundation in one.
Clinique Moisture Surge Tinted Moisturizer
Smashbox BB Cream
I feel your pain! I grew up in a very humid place and my skin was always oily, but the last few years, I've lived in the desert region of the western US and my skin is sooo dry! I've been using a lot of BB creams, but now that its fall/winter I've switched back to foundation. I like Neutrogena Healthy Skin for drugstore and Nars Sheer Glow for high end. I have to be really careful to only use a small amount or it cakes up on me.
you could try the BB cream by skin79 for dry to normal skin, it's great! (make sure to buy it from a legitimate website though - there are a lot of fakes out there!)
nars sheer glow is a fantastic foundation for dry skin too
