I don't know how you feel in your dream and who hurt you. These are all things that need to be said to help you interpret your dreams.
And it may mean that someone hurt your face in real life and showed it in a dream.
It is also possible that you have encountered some anxiety problems in your life. At the same time, because you care more about your appearance, using it in your dreams makes you feel anxious. Because it is a dream, this kind of anxiety helps you to discharge emotional stress.
Dreams themselves play a regulatory role and do not represent or predict what will happen in the future.
