What is Redness?

Redness, or erythema, is a skin condition where the skin becomes red or flushed. It happens when blood vessels near the skin surface widen. This increases blood flow to the area. Redness can be temporary or chronic. It may affect small patches or large areas. Understanding redness helps in managing it.

Common Symptoms of Redness

Redness often comes with other symptoms. These include:

  • Warmth: The red area feels hot to touch.
  • Swelling: Inflammation can cause puffiness.
  • Itching: Many redness causes lead to itchiness.
  • Pain or tenderness: Some conditions cause discomfort.
  • Dryness or flaking: Skin may peel or crack.
  • Bumps or blisters: Certain causes produce raised lesions.

Symptoms vary based on the underlying cause. For example, sunburn causes pain and blistering. Rosacea leads to persistent redness and visible blood vessels.

Causes of Redness

Redness has many triggers. They fall into three main categories.

Environmental Triggers

  • Sun exposure: UV rays damage skin and cause sunburn.
