Every winter the same pattern returns: tight cheeks after washing, flaky shins, cracked knuckles. The cause is mostly physics. Cold air holds very little water vapour, and when that air is heated indoors its relative humidity drops further. Skin loses water to the dry air faster than it can replace it.
Why skin flakes
When the outer layer of skin dries out, the enzymes that help old cells shed neatly work less well. Cells clump and lift instead of flaking off invisibly, which produces the rough, white, scaly look of winter skin. Itch follows, and scratching damages the barrier further.
Habits that help most
- Shorter, cooler showers. Five to ten minutes in warm, not hot, water.
- Moisturise within minutes of washing. Apply cream to slightly damp skin to trap water.
- Switch to richer textures. Creams and ointments instead of light lotions; an extra layer at night.
- Protect hands. Gloves outdoors, hand cream after each wash, and cotton-lined gloves for household cleaning.
- Add humidity indoors. A humidifier in the bedroom can help, if it is cleaned regularly.
- Keep sunscreen. Winter sun, especially reflected off snow at altitude, still burns.
Lips and the face
Lips have no oil glands of their own and crack quickly. A plain balm or petrolatum works well; avoid licking them, which dries them further. For the face, a facial oil layered over moisturiser at night can make a real difference to comfort.
Travel and winter breaks
Ski trips combine cold, wind, altitude and strong UV. Many mountain resorts now come with spas and even casinos, and moving between snowy slopes and overheated interiors is hard on skin. Pack a richer cream than you use at home and reapply sunscreen on the slopes.
If dry patches become red, cracked or very itchy and do not settle with moisturiser, it may be eczema rather than simple dryness. A doctor or pharmacist can advise.
