Acne

Also called: Pimples, Zits

Acne is a common skin disease that causes pimples. Pimples form when hair follicles under your skin clog up. Most pimples form on the face, neck, back, chest, and shoulders. Anyone can get acne, but it is common in teenagers and young adults.

Symptoms

  • Pimples on the face, neck, back, chest, and shoulders

Causes

  • Systemic antibiotics (e.g., tetracycline class, doxycycline, azithromycin)
  • Isotretinoin
  • Desloratadine (used in combination with isotretinoin)
