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:

- Are the spots mainly on your face, chest, or back?
- Do they come and go over time?
