Eschar vs. Scab — What's the Difference?
Edited by Tayyaba Rehman — By Maham Liaqat — Updated on April 29, 2024
Eschar is dead tissue resulting from severe burns or gangrene, typically hard and black, while a scab forms over a healing wound, protecting it.

Key Differences
Eschar forms when skin or tissue is severely damaged, often from burns or gangrene, and becomes necrotic, creating a thick, leathery layer. Whereas, scabs are a natural part of the healing process, forming when blood clots at the site of a minor wound, such as a cut or scrape, to prevent bleeding and protect against infection.
Eschar is generally associated with more severe medical conditions and may require surgical removal to prevent infection and promote healing. On the other hand, scabs are usually left to fall off naturally as the underlying skin heals and regenerates.
The texture of eschar is typically hard and dry, sometimes described as leathery or mummified. In contrast, scabs are crusty and can be slightly raised, with a rough texture that gradually softens as the wound heals.
Eschar can be a sign of a critical medical issue, especially in cases of severe burns or necrotizing fasciitis, where the dead tissue must be removed to access healthier tissue underneath. Meanwhile, scabs generally indicate minor injuries and a normal, healthy healing process.
In terms of medical management, eschars often require careful observation and treatment in a clinical setting to avoid complications like sepsis. Scabs, however, are typically managed at home with minimal medical intervention, simply keeping the area clean and protected.

What is a scab?
A scab is a crusty, protective layer that forms over a wound as it heals, resulting from the clotting of blood.
Why does a scab form?
A scab forms to stop bleeding and protect a wound from infection as it heals.
Are scabs harmful to pick at?
Picking at scabs can delay healing and increase the risk of infection or scarring.
What is eschar and how does it form?
Eschar is dead, necrotic tissue that forms typically after severe burns or cases of gangrene, characterized by a thick, leathery appearance.

Treatment for eschar may involve surgical removal (debridement) to prevent infection and promote healing.
How can you tell if a scab is infected?
Signs of infection include increased redness, swelling, pain, or pus around the scab.
What distinguishes eschar from a scab?
Eschar results from more severe damage and is necrotic tissue, while scabs are part of the natural healing process for minor wounds.
How does eschar affect the body?
Eschar can restrict blood flow and harbor bacteria, potentially leading to severe infections.
What should you do if you have eschar on a wound?
Seek medical attention as eschar might need to be surgically removed to prevent complications.
Is it okay to remove a scab?
Scabs should generally be left alone to fall off naturally to ensure proper healing underneath.
What conditions promote the formation of eschar?
Conditions like severe burns, pressure ulcers, and certain bacterial infections like necrotizing fasciitis can lead to eschar formation.
Can both eschar and scab be present on the same wound?
It's possible, particularly if a wound has varying degrees of severity and healing stages.
How can you care for a wound with a scab?
Keep the area clean and dry, and avoid picking at the scab to allow natural healing.
When should you see a doctor for eschar or a scab?
