Two-step skincare that holds up in forty-degree heat
A regime you will still run when the car door burns your hand. Cleanse when you are dirty, moisturise lightly, protect from UV. Everything else can wait.

Forty degrees is an editor. It cuts the sentence down to what a person will still do with a hot steering wheel and a shirt already stuck to the back. The original eshu idea — simple, effective, no difficult regime — was always a heatwave idea. This is the written protocol.
If you want the climate physics, start with why Australian skin needs a different rulebook. If you want the aisle philosophy, stay here.
The only jobs that matter before sunset
Remove what the day put on you when it is actually on you. Sweat, sunscreen, dust, the film of a city. If you have been in an office with the air-con roaring, you may only need a rinse at lunch and a wash at night. If you have been on a roof, you need a wash that works. See face wash versus cleanser.
Put a little water-holding cream back. Heat plus wind plus inland dryness will still strip a barrier even as you drip. A gel-cream on damp skin is enough for most faces. If you skip this because "oil and heat", you may bounce into a shinier T-zone by 4 p.m. as the skin overcompensates.
Protect from UV as if the temperature were 24. Heat is not the burn. Ultraviolet is the burn. The daily habit does not take January off. A sweat-resistant sunscreen in a quantity that looks greedy, a hat, a shirt. Reapply if you are actually outside.
That is two steps plus the Australian extra. We will not pretend sunscreen is optional so the title stays cute.
What to take out of the line-up
Acids the night before a roof day. A heavy occlusive at 7 a.m. in Dubbo. A strongly scented oil that will live in a car. A new "cooling" product whose menthol will sting the moment you sweat. Tea tree neat on a damp neck.
Exfoliation can wait for a milder evening. When you return to it, use the non-sandpaper version.
Fragrance in heat is louder. If you wear cologne, read scent layering and then use less.
Morning, compressed
Rinse or a light cleanse if you are oily. Gel-cream. Sunscreen. Hat by the door. If you shave, do it the night before so you are not putting SPF on a fresh scrape in a rush. Shaving in Australian water is a longer file.
Breakfast is not a skincare step. Water is not a moisturiser. You may drink it anyway because you are not a fool.
Night, still short
Wash. This is the real cleanse of the day. Cream that can be a little richer if you are sleeping in air-conditioning — the indoor desert does not care that it was 41 at 4 p.m. See winter offices; the same machine runs in January.
If you trained, wash sooner rather than later. Sweat sitting in a synthetic collar is how necks become medical.
The heatwave exceptions
A heat rash is a heat rash. Cool the body, loose cotton, bland cream, not a new active. If it pustules or you feel unwell, stop being stoic.
Lips split in dry heat as surely as in July. A small occlusive stick is part of the two-step even if it looks like a third.
Hands on a steering wheel in a car that has sat in the sun are a burn risk and a dryness risk. Sleeves help. Cream at the petrol station does not make you delicate.
If you are on tools, this essay defers to tradies, salt, cement and sun. If you are on a roster, it defers to the FIFO kit.
A kit that fits in one hand
Cleanser. Light moisturiser. Sunscreen. That is the bathroom. A travel-size of each in the glovebox because heat will wreck a left-behind tube, so replace it when it cooks. Do not store sunscreen on the dash and then trust it.
We are not selling the kit. We are describing the size of a habit that survives the continent. When the temperature drops, you can complicate things if you enjoy complication. In forty-degree heat, you will not. That is the point of a simple regime.
Power outages, cricket and the days the plan breaks
When the power dies in a heatwave, showers get shorter and tempers get longer. Keep a bottle of water for a face rinse and a cream that does not depend on a ritual. Sunscreen still goes on. The sun did not notice the outage.
Cricket, tennis, a backyard that has become an argument — these are the days people invent a third step because they feel they should suffer more. Suffer less. Hat. Shirt. Two steps. Shade that is actual shade, not a beer logo on a thin gazebo.
If you are looking after someone older, their thirst and their skin will tell the truth sooner. Cream on their hands, a hat they will actually wear, and a low bar for calling a nurse on call if they become confused in the heat. A journal stays in its lane. The lane includes telling you when the lane has ended.
A week of doing it, not decorating it
The useful test is seven days, not a new bottle. Write the weather in the morning — hot, dry, humid, recycled — and match the texture you already own. If you add anything, add it on day one only, and leave the rest of the cabinet alone so you can tell what changed.
Keep a photograph in the same bathroom light on day one and day seven. Not for social media. For honesty. Tightness, shine, a rash, a nick that will not settle: those are data. If the week is worse, stop the new thing. If the week is calmer, you have a habit, not a personality.
Carry the smallest version of the habit out of the house. A cream in a bag beats a perfect bathroom you do not visit at lunch. A hat on the seat beats a speech about UV. A hose, a tap, a rinse: the unglamorous verbs still do the work the aisle keeps trying to rename.
Tell one other person the plan if you live with them. Shared soap and shared towels will undo a careful face. Shared cream at the sink will save a pair of hands. This is not intimacy advice. It is logistics.
Workdays will try to steal the plan. A meeting runs late, a site has no tap, a roadhouse soap is a joke. That is why the plan has to be small enough to survive a bad Tuesday. Two steps plus sunscreen will travel. A ten-step will stay in the bathroom and sulk.
On the weekend, resist the urge to "catch up" with a peel, a device, or three natives at once. Catching up is how faces go red before a Monday. Repeat the weekday verbs. If you have sport, rinse sooner. If you have a long drive, wear the sleeve. If you have a roster, pack the pouch before you are tired.
If at any point the skin becomes a story you would not tell a barber — spreading, bleeding, changing, painful, febrile — you are no longer in a journal. You are in a waiting room. Take the timeline. Take the bottle. Leave the forum theories in the car.
The rest is repetition. Climate first. A wash that ends. A cream that matches the air. A sunscreen you will finish. Native ingredients that survive a label reading. Paid words declared, with rel=sponsored where money sat down. That is enough week, and enough continent, for this essay to end on.
Questions we keep getting
- Is two steps really enough?
- On a 40-degree day, two honest steps plus sunscreen will beat six products you skip. Add a third at night if you need a cream. Add a GP if you need a diagnosis.
- What textures survive a heatwave?
- Gel-creams, light lotions, and sunscreens you will reapply. Jars of rich night cream can wait in the fridge or wait until April.
