Why your skin cracks in a Kathmandu winter, in a room with no heating

There is a particular kind of winter misery that belongs to Kathmandu. It is not that the cold is severe by international standards. It is that almost nothing indoors is heated, so you live at the ambient temperature all day, and the ways people warm up are precisely the ways skin gets ruined.

A long very hot bucket bath because it is the only warm ten minutes of the day. A gas heater in a closed room. Sitting close to it because that is where the warmth is. All of it is reasonable and all of it dehydrates skin.

What the cold season actually does

Cold air holds less water vapour than warm air. When that air comes indoors and warms up slightly, its relative humidity drops further, and dry air pulls moisture out of whatever is exposed to it. Your face is exposed to it for sixteen hours a day.

At the same time, the skin's own lipid layer, the mortar that holds the outer cells together and keeps water in, does not perform as well in the cold. Sebum production drops as temperature falls, which is why people with oily skin in July find themselves flaking in January and wonder what happened.

Dermatologists in Nepal describe the seasonal pattern the same way each year: the dry months bring fewer fungal problems than the monsoon and far more dryness and barrier disruption. Altitude compounds it, because the atmosphere is thinner and the winter sun stays strong, so you are getting a meaningful ultraviolet dose on already-compromised skin.

Dry and dehydrated are different problems

These get used interchangeably and they are not the same thing, which is why people buy the wrong product.

Most Kathmandu winter skin is both at once. Oily-skinned people who are dehydrated often make it worse by reaching for the mattifying products that got them through the monsoon.

The three things a moisturiser can do

Ignore the marketing category on the front of the jar and look at what is in it. Moisturising ingredients do one of three jobs, and a winter routine needs all three.

• Humectants draw water into the outer layer of skin. Glycerin, hyaluronic acid, panthenol, urea, propylene glycol. These are the hydration step.
• Emollients sit between the skin cells and smooth the surface, which is what makes skin feel soft rather than rough. Squalane, fatty acids, plant oils, ceramides.
• Occlusives form a film that slows water escaping. Petrolatum, dimethicone, shea butter, lanolin, mineral oil.

The routine, in the order that works

1. Switch your cleanser. A foaming or gel cleanser that was right in the monsoon strips a winter barrier. Move to a cream, milk or low-foam cleanser for the cold months.
2. Apply a humectant to damp skin. Straight out of the shower, within a minute, while the skin is still visibly damp. This is free and it works.
3. Layer a richer moisturiser over it. Cream rather than gel. Ceramide-containing formulations earn their place here because ceramides are part of what the barrier is actually made of.
4. Seal the worst areas. An occlusive balm on cheeks, around the nose and on lips. Plain petrolatum is unglamorous, cheap and extremely effective.
5. Sunscreen every morning regardless. Winter UV in Nepal stays high because the skies are clear and the air is thin.

What to stop doing while the barrier is damaged

If your skin is currently stinging when you apply things that used to be fine, that is a compromised barrier telling you something. Adding more actives to it is the wrong direction.

• Pause exfoliating acids entirely. Not reduce, pause, until skin stops stinging.
• Pause or reduce retinoids to once or twice a week, and apply moisturiser first as a buffer.
• Stop using hot water on your face. Lukewarm, and keep the very hot water for the rest of you if you must.
• Put away the clay masks and the scrubs until spring.
• Stop layering five products. A damaged barrier needs fewer ingredients, not more.

Give it two weeks of nothing but cleanse, moisturise, protect. Most winter skin recovers entirely on that alone, and then you can reintroduce one active at a time.

Living arrangements matter more than products

• A gas heater in a closed room drops humidity fast. Crack a window, and put a bowl or bucket of water in the room if you do not have a humidifier.
• Keep bath water at a temperature you would describe as warm rather than hot, and keep it short.
• Wool directly against the skin is a frequent cause of winter itching that gets blamed on skincare. Wear cotton underneath.
• Lips: stop licking them. The evaporation cycle is why they crack, and a balm with petrolatum breaks it.

When it is not just winter

Some winter skin needs a doctor rather than a better cream.

• Cracks that bleed, particularly on hands and around the mouth.
• Patches that are red, thickened and intensely itchy, which may be eczema flaring seasonally.
• Flaking with redness in the folds around the nose, eyebrows and hairline, which is often seborrhoeic dermatitis rather than dryness.
• Anything that is getting worse despite four weeks of gentle, consistent care.

The spring transition

Do not carry your January routine into April. The rich cream that saved your face through the cold becomes occlusive as soon as the weather turns, and that is where a lot of spring congestion comes from. Lighten the moisturiser, keep the sunscreen, and reintroduce actives gradually.
