For a glowing, dewy finish, you can't beat Benefit Cosmetics! I absolutely love their Blush, Benefit Cosmetics "Bella Bamba" (Link to Sephora Product Page) It really gives your cheek bones a bright, glowing, shimmery finish. Benefit Cosmetics "Posietint" cheek stain (Sephora product page) works nicely too. If you want something more, try layering Benefit Cosmetics "Girl Meets Pearl" (Sephora product page) onto your cheeks after you've applied your blush. "Girl Meets Pearl" is the very best product for giving you a dewey finish. I hope all this helps!
I agree! Try cream blush. Also, the key to a gorgeous dewy look is well moisturized healthy skin. The NARS Aqua gel hydrator is a treatment to help hydrate your skin, but you can also try a great moisturizer (I like NARS balancing moisturizer - it's a gel formulation) and allow it to soak into your skin, wipe off any excess with a tissue and carry forward with your makeup routine. Also, drink lots of water
Other ways to "cheat" is using a product like the NARS Orgasm illuminator on your cheekbone; or mixing NARS laguna or copacabana illuminator (depending on your skintone) in with your moisturizer.
Hope that helps!

For a dewy finish, I would go for a cream blush. Josie Maran's color stick is great, and can be used on the lips too. Here's the link:
