Maybe it is a small area of cellulitis or hair root infection that you may not easily diagnose. Pus is related to bacterial infection. Using antibacterial pomads may help to reduce his complaints.
By pus you mean pus coming out of an infected area of his face? Did he have an injury on the site? Does he have acne problems? When did it start? How old is your friend? Does he have chronic disease? We need more information to say something, please describe his condition further.. but if you are talking about an infection by saying pus, then it is better to go to a doctor since such an infection may require urgent treatment.
