What causes acne and cysts?
Sometimes bacteria get trapped inside the pore, too, causing the area to become red and swollen. Cystic acne happens when this infection goes deep into your skin, creating a red, tender bump that’s full of pus. It may hurt or itch. If a cyst bursts, the infection can spread, causing more breakouts.
