Skin diseases are conditions that affect the skin. These may cause rashes, inflammation, itchiness, or other skin changes. Some skin conditions may be genetic, while lifestyle factors may cause others. Skin disease treatment may include medications, creams, ointments, or lifestyle changes.

What are Skin Diseases?

Your skin is the large organ that covers and protects your body. Your skin has many functions. It works to:

  • Hold in fluid and prevent dehydration.
  • Help you feel sensations, such as temperature or pain.
  • Keep out bacteria, viruses, and other causes of infection.
  • Stabilize your body temperature.
  • Synthesize vitamin D in response to sun exposure.

Skin diseases include all conditions that clog, irritate or inflame your skin. Often, skin diseases cause rashes or other changes in your skin’s appearance.
