Why do small bumps appear on the face with age?

Doctor's answer

The doctor explains the small bumps that appear on the face with age. In men they often start to show around the 40s, and up close they look like tiny volcano craters with a dip in the middle. When the opening of a sebaceous gland on the face gets blocked, sebum builds up inside with nowhere to go and pushes upward, forming the bump.
