What Acne Is

Acne develops when tiny openings in the skin (pores) become blocked with oil and dead skin cells. This can lead to different types of spots.

Bacteria may grow in these blocked pores. This can cause redness, swelling, and tenderness.

Quick self-check:

  • Do you have pimples, blackheads, or bumps on your skin?
  • Are the spots mainly on your face, chest, or back?
  • Do they come and go over time?

  • Upper back

Acne can appear in different areas of the body.

  • Face: Often linked to oil production and hormones
  • Back (bacne): May be related to sweat and friction
