Use lipliner to line your lips. As you can see, you don't have to make a very thin line. For a more natural effect it's better to make the line a little bit thicker.

Apply kissproof lipstick on your lips. Put the lipstick also over the lipliner.

Use a big brush to apply some powderblusher. Choose a color that your cheeks get when you blush. That's a natural color. You don't have to reshape your face, just a natural look! Put a little bit on your cheeks and blend it outwards. With the last bit in the brush, touch your chin, nose and forehead.
