Moisturising Dry Skin Without Causing Maceration

Dry, tight skin is uncomfortable and it cracks easily. But in pressure care, the opposite problem causes just as much damage: skin left too wet becomes soft, pale and fragile — a process called maceration. The aim is to keep skin supple without leaving it soggy, and that comes down to small, consistent habits rather than expensive products.

Why the moisture balance matters

Skin works best when it holds a little water in the upper layers and keeps the rest out. When skin dries out, it loses flexibility, the surface cracks, and those cracks become entry points for infection. A pressure ulcer can begin in a tiny split that nobody noticed.

Too much moisture does the opposite. Skin that stays damp — from sweat, urine, wound fluid or a heavy-handed application of cream — softens and swells. That is maceration. Macerated skin looks white or greyish, feels clammy, wrinkles like fingertips after a long bath, and rubs away far more easily than healthy skin. It is a recognised risk factor for pressure damage, particularly in the skin folds, under the breasts, in the groin, between the buttocks, and wherever a pad or dressing rests against the skin.

Choosing the right emollient

An emollient is simply a moisturiser that traps water in the skin. Many are available on prescription if the person is under the care of a district nurse or GP.

• Lotions are light and easy to spread — useful for hairy skin or large areas, but they need reapplying often.
• Creams suit most people for day-to-day use.
• Ointments, such as white soft paraffin-based products, are thick and long-lasting. They are excellent for very dry, cracked skin but feel greasy and can make the skin under a pad too occluded.

Choose fragrance-free, unperfumed products, and avoid anything containing lanolin if the skin has reacted before. If the person has incontinence, ask a pharmacist or nurse about a barrier preparation containing dimethicone or zinc — these protect skin from urine and faeces rather than simply moisturising it.

One safety point that is easy to forget: paraffin-based emollients soak into clothing and bedding, which makes fabrics more flammable. Keep the person away from naked flames, cigarettes and heaters, and wash nightwear and bedding regularly.

How to apply emollient without overdoing it

More is not better. Thick, smeared layers sit on the surface, trap sweat and soften skin in exactly the way you are trying to avoid.

• Warm a small amount between your palms and spread it thinly — skin should look slightly sheen-like, not wet.
• A useful guide is the fingertip unit: the amount squeezed from the tip of an adult index finger to the first crease covers an area about the size of two flat hands.
• Stroke it in the direction of hair growth rather than rubbing hard.
• Give it three to five minutes to absorb before applying a barrier cream, dressing or pad.
• Aim for two to four applications a day on dry areas, and once daily in skin folds — a light touch only.

Washing and drying: the step most people rush

Use lukewarm water rather than hot, and swap soap for a soap substitute or emollient cream. Soap strips oils and leaves skin drier, which starts the whole cycle again.

Drying matters just as much. Pat gently with a soft towel — never rub — and pay attention to every crease: under the breasts, in the groin, between the buttocks, behind the knees, between the toes, under the arms, and under any fold of skin. Leave the area open to the air for a minute or two before dressing or applying products. If a fold is damp from sweat, a hairdryer on the cool setting, held well away from the skin, can help dry hard-to-reach areas.

Spotting maceration early

Check skin at every reposition and every pad change. Look for:

• Skin that looks white, grey or waterlogged, especially in folds.
• A clammy or soggy feel, with wrinkles that do not disappear.
• Top layers that rub off easily, leaving shiny, raw patches.
• A musty smell, or a rash spreading outwards from a fold.

If you see any of these, stop applying heavy moisturiser to that area, keep it clean and dry, and let air reach it. A light barrier cream is usually more appropriate than an emollient here, and a nurse should take a look.

When to ask for help

Contact the GP, district nurse or tissue viability service promptly if you notice broken skin, a blister or dark patch, redness that does not fade when pressed, swelling, warmth, discharge or a temperature. Out of hours, NHS 111 can advise. Small changes caught early are far easier to treat than a pressure ulcer that has had weeks to develop — and you are not expected to manage this on your own.
