Masterclass GUIDES Introduction This Masterclass Guide is a concise overview of Moisture Associated Skin Damage (MASD). MASD occurs when skin is exposed to moisture for prolonged periods of time, resulting in over-hydrated or eroded skin. This leads to trans epidermal water loss (TEWL) and an elevated skin pH that reduces the skin’s ability to maintain its barrier function.4,5 The end result is separation of the skin layers, which is also known as maceration.
What Are the Risk Factors for MASD?

Body/ Body Fluids
Dermis
■ Direct skin contact with urine and/ or (liquid) faeces ■ Sweat on the skin surface ■ (Increased) wound secretions on the skin surface ■ Other body fluids such as mucus, (tracheal) secretions, or saliva on the
Sweat Gland Hair Follicle Blood Vessels Subcutaneous Layer
skin surface
■ Increased dermal metabolism, elevated local temperature, abnormal skin pH, history of atopy, genetic susceptibility to contaminants, irritants, deep body folds, dermal atrophy, and inadequate sebum production
■ Pressure related injuries, such as immersion foot Skin cleansing procedures and products
■ Repeated or excessive skin cleansing, strong friction or abrasive drying procedures, use of rough materials such as coarse towels
■ Repeated use of harsh skin cleansers ■ Ingredients in skin cleansers such as anionic tensides, fragrances, alcohol, preservatives, essential oils
Mechanical factors
■ Mechanical irritation (friction) from clothing or in skin folds ■ Occlusion, for example due to long periods of lying on non-breathable materials, wearing non-breathable clothing, incontinence pads
■ Pressure or shear forces ■ Skin damage from adhesive products, such as band-aids
How Can MASD Be Prevented? ■ As the onset of MASD often goes undetected, it may first present as basic inflammation of the skin with or without skin breakdown7,8
■ It is often only when significant inflammation, maceration and/ or skin breakdown emerges that clinicians are able to notice and intervene
■ Protection from MASD can be achieved via the application of natural
moisturizers containing pyrrolidone carboxylicacid, urocanicacid, propylene glycol, lactic acid, urea, dimethicone, and petrolatum9,10
■ Preventing MASD with barrier ointments and cyanoacrylates is key for at-risk skin and managing alterations to skin integrity such as IAD, ITD, and peri wound skin damage9,10
■ Preventing MASD requires replenishing the natural moisture of the skin with
moisturizing products such as skin barrier ointments. The skin should be kept clean and free of excess moisture, and a moisturizer or skin barrier cream should be applied daily

Consistency
Water/ lipid Content
Advantages for at-risk skin
Disadvantages for at-risk skin
Lotion
Light and non-greasy
High concentration of water
May have a role in end-of-life skin care and very fragile skin
Increases TEWL; may contain more dehydrating ingredients
Cream
Viscous and nongreasy
Similar parts of oil and water
Spreads easily; creams with quality ingredients can decrease TEWL; aesthetically pleasing
Washes off easily; creams with medicalgrade silicones may not prevent TEWL as well as ointments
Ointment
Thick and greasy
8 parts oil to 2 parts water
Can hold moisture in the skin for prolonged periods; can protect open skin
More difficult to spread; can stain clothing; feels greasy; nonadherence regarding application is possible
Indirect risk factors
■ Old age ■ Care dependency ■ Immobility ■ Malnutrition ■ Obesity ■ Atopic diathesis ■ Microangiopathy and/ or macroangiopathy ■ Reduced sensory functions such as blindness, polyneuropathy, dementia ■ Immunosuppression
