Excoriation describes the damage rather than the underlying diagnosis, despite having a name that sounds ready to invoice you. Neither redness nor a scrape, by itself, tells you what caused the problem.2

Does excoriation mean eczema is severe?

Not by itself. Eczema causes itching and scratching, and both moderate and severe eczema can occur with or without excoriation. Severity also depends on how much skin is affected, how frequent the itching is, skin thickening, bleeding, oozing, cracking, and the effect on sleep and everyday activities. A clinician assesses the whole pattern rather than counting scratch marks. Diagnosing eczema also requires a history and examination, because other conditions can look similar.2

What if the skin is red but not scraped?

Consider what touched the area before the redness appeared. Contact dermatitis is inflammation after contact with a substance. Irritant dermatitis can result from soaps, detergents, chemicals, or friction; allergic contact dermatitis can result from ingredients such as fragrance or preservatives. Cosmetics and hair products can cause reactions on the face, head, and neck. An allergic reaction can appear 24 to 48 hours after exposure, so the timing matters.3

If an irritating substance remains on the skin, rinse the area with plenty of water and avoid further exposure. Moisturizers help skin repair itself in irritant contact dermatitis. Contact dermatitis usually clears within 2 to 3 weeks, but can return if the trigger remains. Seek assessment if the reaction is severe or does not improve after treatment. Use prescribed skin medicines only as directed.3

How do you care for a small excoriation?

For a small, superficial scraped area, use general minor wound care. The terminology gets more elaborate, but the cleaning instructions remain admirably uninterested in Latin.1

  1. 1Wash your hands with soap and water.
  2. 2If the area is bleeding, apply firm pressure with clean gauze or a clean cloth for at least 5 minutes.
  3. 3Gently wash the area with mild soap and water, removing visible dirt. Do not use alcohol, iodine, or peroxide, which can damage tissue and impair healing.
  4. 4Apply petroleum jelly to keep a clean minor wound moist. Do not routinely add antibiotic cream: topical antibiotics can irritate skin.
  5. 5Cover with a sterile nonstick bandage. Change it daily, and keep the wound protected until it heals.

Most small wounds heal within a few days. Pain generally lessens after the first day; pain that worsens a day or more after injury can be an early sign of infection. Check the area during the first several days rather than judging healing by redness alone.5

When should you get medical help?

Seek prompt care for increasing redness, warmth, swelling, tenderness, pus, red streaks, or fever. Infection around a rash can also look purple or brown. Get help for a deep or large scrape, dirt you cannot remove, or bleeding that continues despite pressure. If the injury is dirty and you are unsure whether your tetanus vaccination is current, contact your doctor.1456

A rash that rapidly spreads, blisters, becomes raw, is painful, or involves the eyes, lips, mouth, or genital skin needs medical attention. Trouble breathing or swallowing, or swelling of the eyes or lips, requires immediate emergency care.6
