Preventing MARSI: Choosing Gentle-to-Skin Medical Tape for Fragile Skin

Medical adhesive-related skin injury, usually shortened to MARSI, is one of the most preventable complications in modern patient care, yet it still appears in ward audits, neonatal units and home-care visits every week. The damage is rarely caused by one dramatic event: it develops when an adhesive is chosen for convenience rather than compatibility with the skin beneath it.

This guide explains how MARSI develops, which backing and adhesive combinations are gentlest on fragile skin, and how to build a selection and removal routine that protects patients from the first application to the final peel.

What MARSI Is and Why It Is Still Under-Recognised

The international consensus definition describes MARSI as a visible cutaneous abnormality that persists after the adhesive has been removed.

Clinically, adhesive injuries fall into three families.

• Mechanical injury — skin stripping, tension blisters and skin tears caused by peel force or by tape applied under stretch.
• Dermatitis — irritant contact dermatitis from repeated adhesive contact, or allergic contact dermatitis triggered by one specific component of the adhesive or backing.
• Other adhesive reactions — maceration, folliculitis and moisture trapped beneath occlusive films.

Because skin can look normal for hours after the tape comes off, MARSI is often blamed on fragile skin rather than on the adhesive itself. Documenting every episode, including the product used, the wear time and the removal method, is the fastest way to identify which tapes should leave a formulary.

Three Mechanisms Behind Adhesive Skin Injury

Understanding how an adhesive damages skin makes tape selection far more logical than simply reaching for the roll that sticks hardest.

1. Peel force against the strength of the skin. The stratum corneum is only a few cell layers thick, and its attachment to the layers beneath weakens with age, steroid therapy and chronic illness. A tape tolerated easily on a young forearm can lift the epidermis from an older one in a single pull.
2. Tension and shear. Tape stretched during application contracts as it warms to body temperature, creating stress at the adhesive-skin interface and the classic tension blister.
3. Chemical and moisture exposure. Adhesive residues, rosin-based tackifiers and occlusion all provoke reactions, while trapped sweat or exudate softens skin and makes mechanical damage more likely on removal.

What Makes a Medical Tape Gentle to Skin

Gentle is not a marketing word; it describes measurable behaviour. A skin-friendly tape usually shows most of the following characteristics.

• Low, predictable peel adhesion that stays within the tolerance of compromised skin.
• A conformable, breathable backing that flexes with joints instead of pulling against them.
• Documented biocompatibility through irritation and sensitisation testing within the ISO 10993 biological evaluation series.
• Clean removal with minimal adhesive residue left on the skin.
• An edge that lifts easily, so tape can be released without dragging the epidermis.
• Wear time matched to the task, since the shortest realistic wear time is usually the gentlest choice.

Comparing Backing and Adhesive Combinations

No single tape suits every patient. The table below summarises how the most common clinical tapes behave on fragile skin.

Nonwoven paper tape is the practical starting point for most fragile-skin protocols. Its lightweight backing and low-peel acrylic adhesive hold a light dressing securely while letting skin breathe, and it releases with far less resistance than film or cloth alternatives.

Silk and soft cloth tapes bridge the gap between gentle and durable. They conform around fingers, joints and drainage tubing, which reduces the need to stretch tape during application, one of the most common causes of tension blisters.

Transparent PE film and traditional zinc oxide tapes still have a place: waterproof fixation over intact skin, and compression where high adhesion is genuinely required. Treat them as the exception rather than the default for anyone with compromised skin.

When Tape Is the Wrong Tool

Preventing MARSI sometimes means not using tape at all. If a patient has already had one adhesive injury, or if the skin is paper-thin, oedematous or macerated, an adhesive-free or silicone-adhesive alternative will often hold the dressing just as well.

• Silicone-bordered foam dressings secure a dressing with a gentle silicone contact layer instead of a traditional adhesive.
• Self-adherent cohesive bandages hold without bonding adhesive to fragile tissue.
• Tubular netting and wrap-around fixation suit limbs where tape would circle thin skin.
• Tape-free securement devices for tubing reduce repeated application on the same site.

Where adhesive is unavoidable, limiting the contact area is the next best step: use the narrowest strip that will do the job, and never frame a dressing in a continuous ring of tape.

Application and Removal Technique: The Other Half of Prevention

Even the gentlest tape can injure skin when technique is poor. This sequence covers the steps that most reliably reduce adhesive trauma.

1. Prepare the skin. Clean and dry the site, clip hair rather than shaving it, and avoid alcohol or tincture of benzoin on fragile skin.
2. Plan a short wear time. Reassess adhesive sites every 24 to 48 hours and rotate fixation points where the task allows.
3. Apply without tension. Lay the tape down rather than pulling it, pressing from the centre outwards.
4. Minimise the contact area. Use narrow strips and avoid overlapping layers, since every extra centimetre raises peel force.
5. Loosen the edges first. Lift a corner and support the skin with the opposite hand before peeling.
6. Peel low and slow. Remove tape back over itself at a low angle, in the direction of hair growth, keeping skin taut but not stretched.
7. Use an adhesive remover when needed, then wipe away residue so it cannot affect the next dressing.
8. Inspect and document. Check the skin 30 minutes after removal and record any erythema, blistering or tear as a MARSI event.

Patients Who Need the Gentlest Option First

Certain groups should start on a low-peel tape from the first application rather than after an injury has already occurred.

• Neonates and infants, whose epidermis is thin, loosely attached and easily stripped.
• Older adults, especially those with dry, transparent or inelastic skin.
• Critically ill and long-stay patients, who accumulate multiple adhesive contacts on the same sites.
• Patients on long-term corticosteroids, anticoagulants or chemotherapy, all of which reduce skin tolerance.
• Anyone with oedema, malnutrition, diabetes or previous MARSI, where barrier function is already compromised.
• Patients with ostomies, drains or feeding tubes, where fixation is reapplied frequently.

Sourcing Tapes That Behave the Same Way in Every Batch

Prevention protocols only work when the product itself is consistent. A tape that measures low peel force in one delivery and noticeably higher adhesion in the next will undermine even the best clinical routine.

For distributors, first-aid suppliers and hospital procurement teams, this is where manufacturing discipline matters. A supplier that produces its own medical adhesive, tape backing, jumbo roll and release paper controls the variables that determine how gently a finished tape leaves the skin, and documented systems such as quality control built on ISO 13485:2016 keep those variables inside a defined range.

Consistency also supports the commercial picture. Buyers who need a skin-friendly tape range alongside dressings, bandages and securement products can consolidate specifications with one manufacturer instead of reconciling tolerances across several, and ODM or OEM programmes make it easier to specify adhesive strength, backing type and packaging around a defined patient population.

Frequently Asked Questions

Q1: What does MARSI stand for?

MARSI stands for medical adhesive-related skin injury. It covers erythema, blisters, erosions and tears that persist for 30 minutes or more after an adhesive is removed, including mechanical, irritant, allergic and moisture-related presentations.

Q2: Which tape is gentlest on fragile skin?

Silicone gel adhesives are generally the least traumatic, because they release with very low peel force and leave no residue. Where a traditional adhesive is required, nonwoven paper tape with a low-peel acrylic adhesive is the next gentlest option.

Q3: How long can medical tape stay in place?

Most guidance suggests reassessing adhesive sites every 24 to 48 hours and changing tape as soon as edges lift. The longer an adhesive remains on skin, the stronger the bond becomes and the greater the risk of stripping on removal.

Q4: How is MARSI managed once it occurs?

Management begins with removing the offending adhesive, avoiding further tape on the affected area and protecting the skin with a gentle barrier or silicone dressing. Prevention is the more important step: switch to a lower-peel product, improve technique and document the event.

Key Takeaways for Gentle-to-Skin Fixation

• Choose the least aggressive adhesive that will hold the dressing for the required wear time.
• Match backing and adhesive chemistry to the patient group, not to ward habit.
• Apply without tension and remove slowly at a low angle while supporting the skin.
• Rotate fixation sites and keep wear times as short as the clinical task permits.
• Source from a manufacturer whose peel behaviour stays consistent from batch to batch.

MARSI prevention is a product decision and a technique decision in equal measure. Get both right, and the tape on a fragile patient becomes one of the safest items on the trolley instead of one of the most damaging.
