Skin barrier wipes are disposable cloths saturated with a liquid solution that forms a thin, protective coating on the skin as the carrier liquid evaporates. Their primary function is to safeguard the skin from irritation and damage. They are widely used in medical and personal care settings to provide defense against moisture, friction, and the trauma of repeated adhesive removal.
Mechanism of Barrier Protection
The protective action is based on the rapid formation of a synthetic film on the skin. The liquid solution typically contains polymers, such as acrylates or silicone compounds, dissolved in a solvent that quickly dissipates. Once applied, the solution dries within seconds, usually between 30 and 60 seconds, creating a transparent and durable film.
This polymer film acts as a breathable shield that minimizes contact with external irritants. The film is semi-permeable, allowing oxygen and moisture vapor to pass through, which maintains normal skin function and prevents saturation, known as maceration. The film also reduces friction against clothing and decreases the force required to remove medical adhesives.
Specific Uses in Medical Care
Skin barrier wipes are integrated into medical and personal care where skin integrity is challenged.
Ostomy Management
They are commonly employed in ostomy management to protect the peristomal skin from the corrosive nature of effluent (urine or stool). Applying the barrier film minimizes the risk of Peristomal Moisture-Associated Skin Damage, which can lead to painful skin breakdown.
Preventing MARSI
The wipes are valuable in preventing Medical Adhesive-Related Skin Injury (MARSI) by serving as a buffer layer between the skin and adhesive tapes, dressings, or medical devices. This protection reduces skin stripping or epidermal tears that can occur upon removal of the appliance. This preparatory step ensures the skin remains intact before a device is secured.
Incontinence Care
In the care of individuals with incontinence, barrier wipes shield the skin from prolonged exposure to moisture and irritants found in urine and feces. This continuous exposure can rapidly lead to Moisture-Associated Skin Damage (MASD). The film creates a hydrophobic layer that repels moisture, reducing the likelihood of skin breakdown in vulnerable areas.
Guidance for Proper Application
Effective application begins by ensuring the skin is clean and completely dry. Residual moisture or debris compromises the barrier film’s ability to adhere and form a uniform protective layer. The wipe should be used to apply a single, smooth coating over the entire area requiring protection.
After application, allow the barrier film to dry thoroughly before applying any subsequent adhesive product or medical device. Most manufacturers recommend a drying time of 30 seconds to one minute, depending on the formulation. If the film does not dry completely, it may not set up properly, resulting in a less effective barrier or causing skin folds to stick together.
Reapplication frequency depends on the context and product durability. When used under adhesive products, the film is typically removed with the adhesive, necessitating reapplication with every dressing change. For protection against incontinence, reapplication is generally recommended every 24 to 72 hours, though more frequent applications may be necessary in cases of heavy fluid exposure.
