Overview

Erythema is redness of the skin caused by capillary congestion.

It can be caused by infection, massage, electrical treatments, acne medication, allergies, exercise or solar radiation (sunburn), and waxing and plucking of the hairs any of which can cause the capillaries to dilate, resulting in redness. Erythema is a common side effect of radiotherapy treatment due to patient exposure to ionizing radiation.

It can be caused by infection, massage, electrical treatment, acne medication, allergies, exercise, solar radiation (sunburn), cutaneous radiation syndrome, niacin administration, vitamin A toxicity, or waxing and tweezing of the hairs—any of which can cause the capillaries to dilate, resulting in redness. Erythema is a common side effect of radiotherapy treatment due to patient exposure to ionizing radiation. Circumoral erythema has been described as a typical sign of acute oleander poisoning by ingestion.
