Cold mornings return, and so do pocket sanitisers promising safety with every squirt. Your skin keeps the score, quietly.
As viruses circulate, many of us sanitise dozens of times a day. The habit works for germs, but not always for skin.
The clean-feel trap: why your hands think they’re fine
Instant cool and scent: a reassuring illusion
That brisk chill and tidy fragrance deliver a mental reset. No sink, no splash, no towel. In seconds, you feel sorted. Your palms seem smooth and residue-free. The routine builds trust. Yet sensation and reality do not always match.
Speed feels safe, but quick comfort can mask slow damage that shows up days or weeks later.
What you don’t feel: disruption at skin level
Most sanitisers rely on 60–80% ethanol or isopropanol. These solvents cut through lipids. They clear microbes, but they also dissolve the fatty matrix that holds the outer skin cells together. Your skin does not sting at first. Hidden changes start anyway. Water escapes faster. Irritants seep in more easily. Each round nudges the barrier further off balance.
Your barrier under pressure: lipids, water and a rising itch
How alcohol dismantles your natural shield
The stratum corneum protects you with a “brick and mortar” design. Cells act as bricks. Lipids act as mortar. Alcohols soften that mortar and thin the skin’s slightly acidic film. The surface loses water-binding factors with repeated rubs. Over hours, that means tightness and a rough feel. Over days, fine fissures appear along flex lines and around the nails.
When the lipid film goes, your skin leaks water and welcomes irritants; hydration drops, sensitivity climbs.
From tightness to flakes: a self-perpetuating cycle
Dryness triggers itching. You scratch. Micro-tears form. You sanitise again because the skin feels exposed. More alcohol hits already fragile areas. The cycle accelerates. Redness spreads. Cuticles shred. Pain follows. Once soreness starts, even gentle products can tingle. Many people stop moisturising because it stings, which slows recovery further.
Who gets hit hardest
Children, older adults and atopic skin
Children have thinner skin and a barrier still in training. Older adults renew skin more slowly and produce fewer lipids. People with eczema, psoriasis or contact allergies start with a compromised barrier. They react faster and heal more slowly. Cold air, central heating and frequent handwashing add extra stress across all groups.
Early warning signs you should not ignore
- Persistent tightness after sanitising or washing
- Red patches between fingers or along knuckles
- Flaking around the nail folds and cuticles
- Fine splits that sting with lemon, soap or sanitiser
- Shiny, sore plaques that no longer absorb cream well
Act at the first pull or reddening; early care can prevent weeks of soreness and cracking.
Tiny cracks, bigger risks
When splits invite microbes in
Fissures look small. They open straight lines into the living layers and blood vessels. Skin flora that usually live harmlessly on the surface can enter. Redness deepens, warmth increases, and clear fluid may weep. If pain sharpens or swelling rises, infection may be underway.
The bugs alcohol misses
Alcohol deals well with many viruses and bacteria. It struggles with spores, some non-enveloped viruses and biofilm in wounds. Dry, damaged skin gives opportunists a foothold. Staphylococcus on the skin can flourish in cracks. Yeasts enjoy damp spots under occlusion or plasters. You keep rubbing sanitiser, but the split stays sore because the barrier no longer seals.
Fighting back with hydration
After every rub: rebuild what alcohol strips
Pair each sanitiser use with moisturiser when you can. A no-fragrance, no-colour formula works best. Aim for humectants that pull in water and occlusives that lock it down. Reapplication beats a single heavy layer. Keep a pocket tube with your bottle.
The allies that make a real difference
- Glycerin and hyaluronic acid: draw water into the upper layers
- Ceramides and cholesterol: replenish the skin’s “mortar”
- Urea 5–10%: hydrates and smooths rough patches
- Petrolatum or soft paraffin: seals microcracks overnight
- Niacinamide: supports barrier repair and calms redness
At night, spread a pea-sized amount of petrolatum over splits and cover with cotton gloves. In the day, use a lighter cream after each wash or sanitise. If a cream stings, switch to an ointment base for a week, then reintroduce lighter textures once the sting settles.
Soap or sanitiser: when to pick which
| Situation | Better choice | Why |
|---|---|---|
| Visible dirt or grease | Soap and water | Removes grime and microbes together; alcohol cannot lift soil |
| After public transport | Sanitiser, then moisturiser | Fast germ control when sinks are scarce |
| Before eating on the go | Sanitiser, dry fully | Reduces transfer to food; allow 20–30 seconds to evaporate |
| After the loo at home | Soap and water | Thorough cleanse with less irritation if you moisturise after |
| Contact with bodily fluids | Soap and water, then moisturiser | Mechanical removal beats alcohol; restore barrier promptly |
Should you change your routine
Use less, use smarter: practical swaps
Reserve sanitiser for high-traffic moments: buses, lifts, door handles, shared screens and cash points. Wash with lukewarm water and a mild, fragrance-free soap at home or at work. Pat dry, don’t rub. Apply moisturiser within one minute to trap water. Choose a sanitiser with added glycerin if you sanitise more than six times a day.
Dermatology tips that keep hands clean and comfortable
- Trim hangnails to stop tears; avoid metal cuticle pushers
- Wear nitrile gloves for wet cleaning; moisturise after removal
- Avoid hot air dryers in winter; use paper towels
- Swap scented gels for unscented formulas to reduce irritation
- Rub sanitiser for 20–30 seconds; use enough to wet all surfaces
Extra help for winter hands
Set a “barrier break” each afternoon: skip one sanitiser use and wash once with a gentle soap instead. Plan a weekly reset. After the last wash of the day, apply a ceramide cream, then a thin layer of petrolatum over knuckles and nail folds. Cover with cotton gloves for one hour. This small ritual can halve morning tightness in a week.
If cracks bleed or throb, pause fragranced products and switch to bland ointments for several days. Use liquid plaster only for clean, small splits and remove it at night. Seek medical advice if redness spreads, the area feels hot, or you see pus. Clean habits protect health, but a calm, intact barrier does the heavy lifting. Treat both as a pair and your hands will cope with the season’s germs and the cold alike.
This is the first piece that explains the “brick and mortar” bit so clearly. After a winter of stinging knuckles, pairing sanitiser with a ceramide cream finally makes sense. Any reccomendations for fragrance-free options that don’t feel greasy? Also, is 5–10% urea safe if my skin’s already split?
