At a Glance: Eschar is dead, dried tissue that hardens over a deep wound, often appearing as black, brown, or tan leathery skin. It commonly forms over advanced pressure injuries in people with limited mobility. Because it hides the damage underneath, an eschar wound needs prompt assessment and management from a qualified care team.
Spotting dark, leathery tissue over a sore on a loved one’s skin can be alarming, and knowing how to respond matters. Eschar signals that a wound has reached a serious stage, and the way caregivers and medical professionals react in the first hours and days can shape the path toward healing. By following the right steps, families and care teams can catch it early, report it properly, and lower the odds of it coming back.
What Is Eschar in a Wound?
Eschar is a layer of dead tissue that has dried out and hardened over a wound. It forms when cells lose their blood supply or sustain severe damage, leaving behind a thick, crusted covering. In some ways, it acts like a natural scab, but it sits over deeper wounds and behaves very differently from the thin crust that forms over a minor cut.
How Eschar Forms
When pressure or injury cuts off blood flow to an area, the affected tissue dies and begins to dry. Poor perfusion, meaning reduced circulation to the skin and the subcutaneous tissue beneath it, is the common thread behind most cases of eschar formation. Common causes include:
- Pressure injuries (bedsores): Prolonged pressure compresses tissue against bone, depriving it of oxygen. This is the leading cause, especially for people with paraplegia or quadriplegia who cannot reposition on their own.
- Burns and frostbite: Extreme heat or cold destroys tissue and leaves a dry, hardened surface.
- Infections and poor circulation: Conditions that limit blood flow or damage tissue can also trigger tissue necrosis and the eschar that follows.
What Eschar Looks Like
Eschar has a recognizable look and feel that sets it apart from healthy skin and from the reddish-pink granulation tissue that appears as a wound heals:
- Color: Black, dark brown, tan, or sometimes gray
- Texture: Leathery, hard, and dry to the touch
- Edges: Sometimes loose at the border, sometimes firmly attached to the wound bed
- Pattern: Often looks like thick, crusty skin sitting over the wound
Why an Eschar Wound Matters for Caregivers
Eschar alerts the care team that tissue damage has gone deep, and it creates real challenges for treatment.
The Risks Hidden Beneath the Surface
- Masks severity. Because intact eschar covers the wound bed, providers cannot measure the true depth. A pressure injury hidden by slough or eschar is classified as an unstageable pressure injury, meaning the real stage stays unknown until the surface is cleared.
- Hides an infection. Dead tissue can trap bacteria, and an infected wound may go unnoticed under the surface.
- Delays healing. Devitalized tissue blocks the new tissue repair the body needs, so the wound often cannot close until the eschar is addressed.
- Signals a Serious Stage. An eschar wound usually points to an advanced injury, similar to a Stage 4 bedsore, that calls for medical attention.

Caregiver Responsibilities: Spotting and Responding to Eschar
Family caregivers are often the first to notice skin changes, which makes daily attention one of the most valuable things you can offer.
Where to Check During Daily Skin Inspections
Look closely at high-risk areas during bathing or repositioning, watching for redness, warmth, firmness, or discoloration before any eschar has a chance to form:
- Heels and ankles
- Sacrum and tailbone
- Hips and shoulders
- Back of the head
What to Do When You Find Eschar
- Do not try to remove it yourself. Eschar removal is a medical procedure, and pulling or cutting at dead tissue can cause bleeding, pain, and infection.
- Document it. Note the size, color, and location, and take a clear photo if you can.
- Call the provider promptly. Share what you see and ask for a wound assessment.
- Keep watching. Report any growth, odor, drainage, or spreading redness right away.
Talking With the Care Team
Clear communication helps a wound care specialist act faster. Coming prepared with details saves time and supports better decisions.
Questions to Be Ready to Answer
- When did you first notice the eschar?
- Has it changed in size, color, or texture?
- Is there any odor or drainage?
- What does the current pressure relief routine look like?
A clinician decides whether the eschar should be removed and which method fits. Options can range from enzymatic debridement using topical treatments to surgical debridement for deeper wounds. A stable eschar that is dry and firmly attached, often on the heel, is sometimes left in place on purpose because it can act as a protective cover. That call belongs to a healthcare professional, never to a caregiver.
Prevention: Your Most Important Role
Stopping a wound before it starts is always better than treating one. Most pressure injuries, and the eschar that can follow, are preventable with steady daily habits.
Daily Habits That Protect the Skin
- Reposition often. Turn or shift the person about every two hours, or as the care team directs, to relieve pressure on bony areas.
- Care for the skin. Keep skin clean and moisturized, but not damp, since excess moisture weakens healthy skin.
- Support good nutrition. Adequate protein and hydration give skin the building blocks it needs to stay strong and repair itself.
- Use the right surfaces. Cushions, padding, and pressure-relieving support surfaces lower the load on at-risk areas.
- Act on early signs. Address redness or firmness the moment you notice it, before tissue damage sets in.
How Therapeutic Support Surfaces Help
For people who cannot reposition themselves, the right surface does part of the work for them. Air-fluidized therapy beds move warm air through fine silicone beads to create a soft, fluid-like surface that spreads pressure across the whole body. By reducing friction and shear, these beds lower the risk of new pressure injuries and support healing when wounds are already present. Care teams often consider them for high-risk patients or those recovering from advanced wounds.
