I recently had my make up done professionally for the first time, and one of the biggest differences from what I do myself and what I've noticed from looking at professional pictures, is how seamless cheek make up looks. I've attached an example. I'm guessing it's a case of brushes? If anyone can advise of a technique, product or brush set that's going to help then please do. I think this shows cheek contour, colour on apples of cheeks and highlighting, but just blended so so well. I think I tend to make my cheeks look flat when I do them. Hopefully someone in the know will have the answers!
