How to Check Skin for Early Pressure Damage

Skin checks are one of the most valuable things a carer can do, and one of the easiest to let slide on a busy day. Ten minutes of careful looking can be the difference between a patch of red skin that settles within a day and an open wound that takes months to heal. This guide covers what to look for, where to look, and what to do if something changes.

Why daily checks matter

Pressure damage begins long before the skin breaks. When someone sits or lies in one position for too long, the blood supply to the skin and the tissue beneath it is squeezed. The first visible sign is usually a change in colour, warmth or texture that does not fade when you press it. At this early stage, the damage is often reversible. Left alone, it can progress to a blister, then to a wound that reaches deeper tissue — painful, slow to heal, and vulnerable to infection.

Some people are at much higher risk and need especially close attention:

• Anyone who is immobile, or who needs help to change position
• People with reduced sensation, including those with diabetes or a spinal injury
• Those who are unwell, dehydrated, or eating very little
• Older adults with thin, fragile or dry skin
• Anyone with incontinence, or who sweats heavily
• People using wheelchairs, splints, casts, oxygen tubing or other equipment that presses on the skin

When and how to check

Check once every day, ideally at the same time so it becomes habit. The best moment is during personal care, when clothing is off and you can see the whole body. Daylight or a bright lamp makes a real difference — you will miss subtle colour changes in dim light.

• Look at the base of the spine and sacrum, heels, hips, elbows, shoulders, ears and the back of the head.
• Check both heels every single day. Heels are one of the most common sites and damage there can happen surprisingly fast in bed.
• Look under and around any device: catheter tubing, oxygen tubing, catheter straps, compression garments, splints, casts, hearing aids, glasses, and the edges of masks.
• Compare one side of the body with the other. Differences between left and right are often the first clue.
• Use a mirror, or ask a colleague, for areas you cannot see well.

What to look for: redness and the blanching test

On lighter skin, the earliest sign is a patch of redness. Press it firmly with a clean finger for a few seconds and let go. Healthy skin will briefly turn pale — this is called blanching — and then return to its normal colour. If the area stays red, purple or blue and does not blanch, that is early pressure damage. It may feel warm, firm or slightly swollen compared with the skin around it. This is not a bruise and it is not something to rub better.

Checking skin on darker skin tones

On brown and black skin, redness is much harder to see, and relying on it alone means damage gets missed. Instead, look for:

• A patch that looks darker, purple, blue or ashen compared with the surrounding skin
• Skin that looks shiny, tight or slightly swollen
• An area that feels warm, cool, firm or "boggy" compared with the other side
• A change in texture, such as skin that feels unusually dry, papery or spongy

Ask the person if the area feels sore, numb, burning or "different" from usual. Their own sensation can be the earliest warning of all.

Other early warning signs

• Blisters or a blood-filled spot, even a small one
• Broken or grazed skin over a bony point
• Swelling or hardening under the skin
• Moisture damage — sore, shiny, inflamed skin in skin folds or around the bottom, which weakens skin and makes pressure damage more likely
• Colour changes that come and go — still worth noting, as they may mean pressure is building

What to do if you spot a change

If an area is red and non-blanching, or the skin looks different in any way:

• Take the pressure off it. Change position and help the person keep weight off that area.
• Do not rub or massage the patch. Massage can damage tissue that is already struggling.
• Keep the area clean and dry. Gently pat rather than rub, and use a barrier cream if there is moisture from urine or sweat.
• Document it. Note the date, the exact position, what it looks like, and whether it blanches. A photograph taken with consent is very helpful for tracking change.
• Keep checking. If it has not improved within 24 hours, or gets worse, contact the district nurse, GP or the person's care team the same day.
• Seek urgent help if you see broken skin, a blister, a black or dark purple area, a foul smell, or if the person becomes feverish or unwell.

Alongside daily checks, the basics make the biggest difference: reposition in bed roughly every two hours and in a chair every hour, encourage small shifts of weight between moves, keep skin clean and moisturised, and make sure the person is drinking and eating enough. If you are ever unsure about what you are seeing, take a photograph if you can and ask a healthcare professional. Checking early is never a fuss — it is exactly the right thing to do.
