As the Weather Turns Cold, Are You Prepared for Winter's Dry Skin Season?

The cold has deepened, and winter is truly here. As the air turns dry this time of year, many of you may be noticing your skin feeling drier too.
Even if you're not seeing obvious trouble like flaking or visible dryness, winter skin tends to grow drier little by little, so it's worth staying alert. If dryness progresses, it can even contribute to signs of aging like fine lines.
Let's understand why winter skin is so prone to dryness, and look at how to bring in the right care to protect against it.

Why Does Winter Skin Dry Out So Easily?

If you keep a hygrometer at home, you've probably noticed that humidity, which often sits around 60% in summer, can drop into the 40% range come winter. When the air is this dry, more moisture tends to evaporate from the surface of the skin.
On top of that, winter living often means relying on air conditioners, heaters, underfloor heating, heated carpets, and kotatsu to stay warm. When skin is warmed locally like this, moisture is gradually lost through subtle perspiration.
Meanwhile, oil production naturally decreases as temperatures drop. Oil normally forms a protective film on the skin's surface that helps prevent internal moisture from evaporating — so with less oil production in winter, that protective function tends to weaken as well.
When skin loses moisture, it loses its natural softness and can become hard and rough.
This can create a frustrating cycle: toners and serums struggle to absorb into skin in this state, making it even harder to restore moisture and allowing dryness to progress further — so it's something worth paying close attention to.
