Try applying a small amount and spreading that around with your fingertips, and then see where that leaves you. If you want more, apply more, but remember to always blend into your skin very well, making sure definit lines around your blush don't exist.
I'm not a big fan of cream blush, personally. However, I did own a pot of cream blush once and used it for a while. I always applied it underneath my foundation, because, at least on my skin, my foundation made it look more naturall. I understand if you don't want to use a foundation, I find that alot of women actually hate it. (Even if they do wear it! Hah) If you are going to go for a foundation, however, go to MAC or another department store brand where they can match the foundation *pefectly*. My MAC foundation is like my skin in a bottle. Hopefully this helped you some!
