Shivering is a result of activation of the erector pili muscles. These
muscles are not found in the face, consequently, you do not see "goosebumps"

Please visit this site for further explanation.

A quote from the kids health site:

And what about when you're ice skating or sledding and suddenly saying
"brrrr!!" When you are cold, your blood vessels keep you warm by narrowing
as much as possible, and keeping the warm blood away from the skin's
surface. You won't sweat at all, but you might notice tiny bumps on your
skin. Most kids call these "goosebumps," but the fancy name for it is the
pilomotor (say: pie-low-mo-ter) reflex. This is when special tiny muscles 
called the erector pili (say: ee-reck-tur pie-lee ) muscles pull on your
hairs and make them stand up very straight. This traps warm air between the
hairs and keeps you warmer.

Thank you for your question.
