Excoriation: Appearance, Causes, Treatment, Dressings, and Healing

Excoriation results from superficial mechanical skin damage such as scratching, rubbing, picking, friction, or other mechanical trauma; moisture can contribute by weakening the skin barrier. Excoriated skin often appears raw, red or pink, irritated, and painful. The injury may be linear, scattered, or irregular depending on the cause.

Although excoriation injuries are often shallow, disruption of the skin barrier can increase vulnerability to pain, infection, moisture-associated skin damage, delayed healing, and further breakdown. Identifying the source of skin trauma is essential because excoriation is primarily a mechanical injury, while moisture, wound drainage, ostomy leakage, incontinence, adhesives, and other factors could increase the skin’s vulnerability or contribute to continued breakdown.

Key takeaways Excoriation is superficial skin damage caused by scratching, rubbing, picking, friction, or other mechanical trauma. Excoriated skin typically appears red or pink, raw, shallow, and irritated. It may burn, sting, itch, bleed lightly, or weep. Common contributing factors include pruritus, incontinence, wound exudate, ostomy leakage, moisture-associated skin damage, adhesives, friction, shear, and repeated cleansing. Treatment focuses on correcting the cause, protecting the skin barrier, controlling moisture, reducing friction, relieving itch, and preventing additional trauma. Dressing options may include silicone contact layers, non-adherent dressings, foam dressings, hydrofiber dressings, alginates, barrier films, and moisture barrier creams. Denudation and excoriation can overlap, and terminology may vary by facility or documentation practice. However, Denudation is often associated with moisture-related skin barrier breakdown, while excoriation emphasizes superficial mechanical trauma. A patient may have both conditions; for example, incontinence may contribute to denudation of perineal skin, while repeated wiping or scratching may add excoriation. Foul odor is not typical of uncomplicated excoriation and may indicate infection, trapped drainage, necrotic tissue, or contamination. Mild excoriations may improve within several days once the cause is controlled. More extensive or complicated injuries may require longer to heal.

What is excoriation?

Excoriation is a superficial break in the skin caused by mechanical trauma, such as scratching, rubbing, scraping, picking, or friction. The epidermis is damaged, and the superficial dermis may also be exposed.

In wound care, excoriation may occur around another wound or in areas where skin has been weakened by moisture exposure, such as periwound, perineal, or peristomal skin. Moisture-associated skin damage (MASD) can weaken the skin barrier and make the skin more vulnerable to mechanical injury from wiping, friction, scratching, adhesive removal, or repeated cleansing.

MASD includes conditions such as incontinence-associated dermatitis, periwound moisture-associated dermatitis, peristomal moisture-associated dermatitis, and intertriginous dermatitis. These conditions may coexist with excoriation, but they are more closely associated with moisture-related skin barrier breakdown than with mechanical trauma itself.

What does excoriated skin look like? 

Excoriated skin commonly appears:

• Red, pink, or bright red.
• Raw, abraded, or scratched.
• Superficial or shallow.
• Linear, streaked, scattered, or irregular.
• Moist, shiny, or weepy.
• Painful, tender, itchy, burning, or stinging.
• Fragile or prone to light bleeding.
• Surrounded by irritation, maceration, rash, or discoloration.

Scratch-related excoriations may appear as linear parallel lines or individual scratch marks. When moisture and friction become contributing factors, the injury may appear more diffuse and irregular, particularly on the buttocks, groin, perineum, skin folds, periwound skin, or around an ostomy.

Assessing excoriated skin

Diagnosis is usually clinical. Assessment should consider the wound’s appearance and pattern, patient symptoms, and potential causes.

Clinicians should evaluate whether the skin is exposed to urine, stool, perspiration, wound drainage, or ostomy effluent and whether scratching, friction, adhesives, or medical devices are contributing to the injury.

Surrounding skin should also be assessed for maceration, erythema, fragility, or discoloration. Odor, purulent drainage, warmth, swelling, worsening pain, and spreading redness can indicate complications requiring further evaluation.

Color provides additional clues. Pink or red superficial tissue is common with excoriation, while white or wrinkled surrounding skin may suggest maceration. Yellow or green drainage warrants further assessment, especially if it is thick, increasing, malodorous, or accompanied by pain, warmth, swelling, or spreading redness. Purple, maroon, gray, black, or dusky tissue can indicate more serious tissue damage and should not automatically be classified as simple excoriation.

What causes excoriation?

Excoriation can result from one or more contributing factors.

Scratching and itching

Itching is a common cause. Dry skin, eczema, allergic contact dermatitis, fungal infection, medication reactions, neuropathic itch, and other conditions can prompt repeated scratching and damage the skin barrier.

Persistent or recurrent skin picking may also cause excoriation. When patients have difficulty controlling the behavior, clinicians may need to assess dermatologic, behavioral health, neuropathic, or other contributing conditions.

Moisture and incontinence

Excess moisture softens and weakens the epidermis, increasing susceptibility to friction, shear, cleansing-related trauma, and irritants.

Urine and stool can contribute to inflammation, maceration, and moisture-associated skin damage, while repeated wiping, rubbing, scratching, or cleansing may lead to excoriation of already fragile skin. Incontinence-associated skin damage commonly affects the buttocks, perineum, inner thighs, sacrum, and gluteal cleft.

Wound drainage and ostomy leakage

Wound exudate can damage surrounding skin when drainage is not adequately contained or absorbed. Prolonged exposure to wound drainage may contribute to periwound moisture-associated skin damage (MASD) or denudation, resulting in pain, leakage, wound enlargement, and difficulty maintaining an effective dressing seal. Mechanical trauma from cleansing, wiping, friction, or adhesive removal may also contribute to excoriation of already fragile skin.

Similarly, stool or urine leaking beneath an ostomy pouching system can cause peristomal moisture-associated skin damage or denudation. The resulting skin breakdown may interfere with pouch adherence, leading to continued leakage and further tissue damage. Repeated cleansing, friction, or adhesive trauma may also contribute to excoriation of vulnerable peristomal skin.

Adhesives, friction, and cleansing

Tape, dressings, and securement devices may injure fragile skin during application or removal. Friction from linens, briefs, clothing, skin folds, braces, tubing, and other devices can also abrade the epidermis, particularly when skin is moist.

Frequent scrubbing, strong soaps, alcohol-based products, and repeated wiping may worsen irritation. Gentle cleansing is generally preferred for skin affected by moisture-associated damage.

Excoriation versus denuded wounds

Excoriation and denudation are related terms and may overlap clinically, but they emphasize different characteristics.

Feature	Denuded wound	Excoriation
Core meaning	Loss of the epidermis, leaving superficial tissue exposed	Superficial injury associated with scratching, rubbing, picking, scraping, or friction
Common causes	Moisture, drainage, incontinence, ostomy leakage, friction, or adhesive stripping	Scratching, abrasion, picking, friction, moisture, or adhesive trauma
Appearance	Raw, moist, shiny, red or pink, and often diffuse	Raw, scratched, linear, irregular, scattered, or abraded
Documentation focus	Epidermal loss and exposed skin	Mechanism of injury, especially scratching or abrasion
Treatment focus	Protect exposed skin and control moisture	Stop ongoing trauma, manage itch or moisture, and protect the skin

A patient may have both conditions. For example, incontinence can cause denudation of perineal skin, while repeated wiping or scratching adds excoriation.

Rather than relying only on terminology, clinical documentation should describe the injury’s appearance, location, likely cause, drainage, odor, pain, surrounding skin, and progression.

Does excoriated skin smell?

Uncomplicated excoriated skin should not have a strong or foul odor. Mild odor may occur when sweat, urine, stool, drainage, or ostomy effluent becomes trapped beneath a dressing, pouching system, or within a skin fold.

Persistent or foul odor is more concerning when accompanied by the following:

• Purulent drainage.
• Increasing pain.
• Spreading redness.
• Warmth or swelling.
• Fever or chills.
• Tissue discoloration.
• Delayed healing.
• Wound enlargement.

Odor alone does not confirm infection, but new or worsening odor combined with other clinical signs warrants further evaluation.

How to treat excoriation

Treatment depends on the underlying cause, location, drainage, moisture level, infection risk, and individual patient factors. The primary goals are to stop the continued trauma, protect the skin barrier, maintain moisture balance, reduce symptoms, and support healing.

1. Identify and address the cause

Excoriation may recur if the source of injury persists. Clinicians should assess for itching, incontinence, wound exudate, ostomy leakage, adhesives, friction, shear, fungal infection, and repetitive skin picking.

Interventions may include treating the underlying cause of itching, improving incontinence management, correcting an ostomy pouch seal, selecting more absorptive dressings, reducing unnecessary dressing changes, or changing products that cause adhesive trauma.

2. Cleanse gently and protect the skin

Cleanse excoriated skin gently and avoid scrubbing. A pH-balanced cleanser may be appropriate, particularly for moisture-associated skin damage. Pat the skin dry rather than rubbing.

Barrier products can protect skin from urine, stool, drainage, friction, and ostomy effluent. Options may include moisture barrier creams formulated with zinc oxide, petrolatum, or dimethicone, as well as polymer barrier films and other clinician-selected skin protectants.

3. Maintain moisture balance

Excess moisture contributes to maceration and further skin damage, while excessive dryness can interfere with healing. Dressing selection should therefore correspond to the amount of drainage.

An area with light drainage may require only protective dressing. Moderate or heavily draining wounds may require more absorptive products to prevent moisture from accumulating on the wound and surrounding skin. Consider dressings with vertical wicking capability to absorb and retain drainage within the dressing, helping reduce periwound moisture-associated skin damage

4. Reduce friction and scratching

Positioning strategies, lift devices, pressure redistribution surfaces, protective dressings, and clothing or linens that minimize rubbing can reduce further mechanical trauma. Avoid dragging the skin during transfers and repositioning.

When itching causes excoriation, treating the underlying cause is essential. Depending on the cause, clinician-directed treatment may include emollients, topical medications, antifungal treatment, antihistamines, neuropathic itch management, or dermatologic evaluation.

Keeping nails short, covering the affected area, and using protective dressings may also help prevent repeated scratching.

5. Address suspected infection

Because excoriation disrupts the protective skin barrier, infection can develop. When infection is suspected, clinicians should assess for additional clinical signs and determine whether further evaluation, wound culture, antimicrobial therapy, or specialty referral is warranted. 

What dressing is best for excoriated skin?

No single dressing is best for every excoriation. Selection depends on drainage, location, skin condition, adhesive tolerance, infection risk, and the cause of the injury.

Wound presentation	Potential options	Purpose
Superficial excoriation with minimal drainage	Silicone contact layer, nonadherent dressing, light cover dressing, or barrier film	Protects injured skin and reduces dressing-change trauma.
Excoriation caused by scratching	Nonadherent cover dressing, silicone-bordered foam, or retention netting when appropriate	Creates a protective barrier against additional mechanical trauma.
Incontinence-associated dermatitis (IAD) or moisture-associated skin damage (MASD)	Moisture barrier cream, zinc oxide barrier, polymer barrier film, absorbent products, and structured cleansing	Protect skin from moisture and irritants while supporting barrier recovery.
Periwound MASD or denudation from exudate	Foam, hydrofiber, alginate, superabsorbent, and skin barrier products	Manages exudate and protects surrounding skin from moisture damage.
Fragile or medical adhesive-related skin injury (MARSI)	Silicone-bordered foam, silicone tape, adhesive remover, or nonadhesive securement	Reduces epidermal stripping and dressing-related trauma.
Peristomal MASD or denudation	Appropriate pouch fit, barrier ring, stoma powder, and skin barrier film	Protects skin from effluent and supports pouch adherence.
Suspected local infection or elevated bioburden	Clinician-directed antimicrobial dressing when appropriate	Helps manage local bioburden when clinically indicated.

Dressings that adhere strongly to fragile skin or require traumatic removal should generally be avoided. Occlusive products can be useful in selected situations but may worsen maceration if moisture and drainage are not adequately managed.

How long does excoriation take to heal?

Healing depends on the cause; the injury’s size and depth; moisture control; infection; continued friction or scratching; and the patient’s overall health.

Mild, superficial excoriations may begin to improve within several days once the cause is controlled. More extensive injuries may take longer to heal, particularly when contributing factors are not adequately controlled.

Continued exposure to urine, stool, wound drainage, ostomy effluent, adhesives, pressure, or friction can prolong healing. Diabetes, impaired circulation, infection, poor nutrition, edema, impaired immune function, and continued scratching or picking may also contribute to delayed healing.

Signs of healing include reduced redness, pain, burning, itching, drainage, and maceration, along with healthier surrounding skin and gradual resurfacing of the wound.

When should excoriation be evaluated?

Patients and caregivers should contact a healthcare professional if excoriated skin develops any of the following:

• Increasing pain, burning, itching, or tenderness.
• Spreading redness, warmth, or swelling.
• Foul odor.
• Yellow, green, thick, or purulent drainage.
• Fever, chills, or feeling unwell.
• Purple, black, gray, or dusky discoloration.
• Bleeding does not stop with gentle pressure.
• Rapid enlargement or increasing wound depth.
• Peristomal skin breakdown that prevents pouch adherence.
• Failure to improve despite appropriate skin protection and management of contributing factors.
• Recurrent breakdown in the same location.
• Repetitive scratching or picking that the patient cannot control.

Early evaluation can help identify underlying causes, address complications, and prevent superficial skin damage from progressing into a more complex wound.

Frequently Asked Questions

What does excoriated skin look like?

Excoriated skin may appear pink, red, raw, scratched, shiny, moist, or weepy. Scratching may produce linear marks, whereas excoriation occurring in skin weakened by moisture exposure may appear more diffuse or irregular, particularly when friction, cleansing, wiping, or other mechanical trauma is involved.

Is excoriation the same as denuded skin?

Not exactly. Denuded skin refers to loss of the epidermis, often associated with moisture-related skin barrier breakdown, while excoriation typically emphasizes superficial mechanical injury caused by scratching, rubbing, picking, or abrasion. The two conditions can occur together.

What causes excoriation?

Excoriation is most commonly caused by mechanical trauma such as scratching, rubbing, picking, friction, shear, adhesive removal, or repeated cleansing. Moisture exposure from incontinence, wound drainage, ostomy leakage, or moisture-associated skin damage may weaken the skin and increase the risk of excoriation.

Does excoriated skin smell?

Uncomplicated excoriation should not produce a strong odor. Foul or persistent odor can occur with infection, trapped drainage, necrotic tissue, or contamination; it should be assessed alongside other clinical findings.

How do you treat excoriated skin?

Treatment involves identifying and addressing the cause, gently cleansing the skin, controlling excess moisture, protecting the skin barrier, reducing friction and scratching, selecting an appropriate dressing, and addressing infection when present.

What dressing is best to use for excoriated skin?

Treatment focuses on identifying and correcting the source of mechanical injury, protecting the skin barrier, and managing contributing factors. Depending on the clinical situation, options may include silicone contact layers, nonadherent dressings, foam dressings, hydrofiber dressings, alginates, barrier films, and moisture barrier products.

Should excoriated skin be covered?

Covering the area may protect it from scratching, friction, drainage, contamination, and further mechanical trauma. Whether the area should be covered depends on the cause. Dressing selection should consider moisture level, drainage, location, adhesive tolerance, and the condition of the surrounding skin.

How long does excoriation take to heal?

Mild, superficial excoriation may improve once the cause is controlled. More extensive or complicated injuries may take longer to heal depending on the severity of the injury and individual patient factors.
