Erythema is redness of the
skin caused by
capillary congestion.
Causes
It can be caused by
infection,
massage, electrical treatments,
acne medication,
allergies, exercise, solar radiation (
sunburn), or 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.
In about 30-50% of cases, the cause of Erythema is unknown.
