How Does the Dry Highveld Climate Affect Your Skin Barrier?
Share
If your skin feels tighter and itchier the moment winter hits Johannesburg or Pretoria, you're not imagining it. The Highveld's dry, high altitude winter air pulls moisture out of skin faster than a humid climate does, and that moisture loss is what weakens your skin's natural barrier. For eczema-prone skin, a barrier that's already struggling to hold onto moisture has even less room to cope, and flare-ups tend to cluster in these colder, drier months.
Here's what's actually happening. Skin naturally loses a small amount of water through its surface all the time, but low humidity speeds that process up. At altitude, the air is thinner and drier still, so Johannesburg and Pretoria's elevation adds to what winter is already doing, and the wide day-to-night temperature swings typical of the Highveld don't help either. The result is skin that feels rougher, tighter, and more reactive, exactly the conditions that make eczema harder to keep calm.
It's frustrating when your skin gets worse the moment the season changes, especially once you've found a routine that usually works through summer. At Repcillin, we formulate a 100% natural, cortisone-free crocodile oil balm specifically to help support that barrier when conditions turn against it, rather than adding synthetic ingredients your skin has to work around.
What actually helps in dry Highveld air
Two things make the biggest difference during dry months. First, seal moisture in right after you wash or shower, while skin is still slightly damp, rather than waiting until it's already dried out. Second, switch to a thicker, more protective balm than you'd reach for in humid summer weather. A thin lotion that's fine in December often isn't enough once winter humidity drops and wind picks up, which is exactly why Repcillin's High Concentrate balm is formulated thick and deeply nourishing rather than light and watery. A small amount goes further at holding that protective layer in place than a lot of a thinner product would, and consistency matters more than quantity.
Left unaddressed, that seasonal dryness tends to compound. Tighter skin cracks more easily, cracked skin itches more, and constant itching disrupts sleep and confidence right when you need your skin to hold steady the most.
The goal isn't to fight the Highveld's climate, it's to give your skin barrier what it needs to handle it through the dry months, so you're not starting from scratch every winter. See how Repcillin's natural approach to eczema care works.
Frequently asked questions
Does dry climate make eczema worse?
Generally, yes. Low humidity increases how much moisture your skin loses through the day, and skin that's already dealing with eczema has a harder time compensating. That's part of why many people notice more flare-ups in dry winter months than in humid summer ones.
Why does high altitude cause dry skin?
Higher altitude means thinner, drier air, so moisture evaporates from skin faster than it does at sea level. Johannesburg and Pretoria's elevation, combined with low winter humidity, is a big part of why Highveld skin tends to feel tighter and flakier this time of year.
Can dry air trigger eczema flare-ups?
It can, especially for skin that already has a compromised barrier. Dry air doesn't cause eczema on its own, but it strips away one of skin's main defenses, moisture, which makes flare-ups more likely and existing ones harder to calm down.
