Causes and Diagnoses

Causes and Diagnoses of Acne

Acne occurs when pores get clogged and bacteria grow inside the pore, causing inflammation. There may be a number of reasons why some people get acne and others don’t. They include:

  • Medications, including corticosteroids
  • Oil and grease from the scalp and makeup
  • Diet
  • Irritation from squeezing pimples
  • Friction from clothing, helmets or backpacks
  • Pollution
  • Irritation from humidity or exposure to the sun
  • Hormone level changes:
    • At puberty
    • During the menstrual cycle
    • During pregnancy
    • From birth control pills
    • From stress

When you’re stressed out, your body produces more androgens, the hormone that stimulates oil glands and hair follicles in the skin. There is also a genetic component to acne. If someone else in your immediate family has acne, you are more likely to get it as well.

Your physician can diagnose acne during a physical exam.
