Hello Natakrit. The problem you are facing could be due to many factors. The most common error is to have the geometry's "primary visibility" off. To check if it's on, select your character's face geo and press Ctrl+A to see its Attributes. On its Shape tab, open the "Render Stats" and see if "Primary Visibility" is off. By default all these should be checked.
If you work with render layers, check if whatever layers are on, contain the face geo.
Also, by selecting the CtrlBox (the yellow square that surrounds the face controllers), you can turn off the "Render Spheres" so they don't show up on your renders as in the image you provided.
Hope that helps!
