Why Skin Gets Worse in Winter (And How to Protect Your Skin Barrier Naturally)

Why Does Skin Get Worse in Winter?

It’s not just seasonal—it’s biological.

Cold air, low humidity and indoor heating disrupt your skin barrier, increasing water loss and sensitivity.

This is why many people across New Zealand and Australia notice:

  • worsening eczema
  • increased dryness
  • more redness or flare-ups

What Happens to Your Skin in Winter - 5 Key Changes

1. The Skin Barrier Becomes Less Effective

Your outer skin layer (stratum corneum) is made up of:

  • corneocytes (skin cells)
  • lipids (ceramides, cholesterol, fatty acids)

These lipids act like a seal to keep moisture in.

In winter:

  • lipid production decreases
  • lipid structure becomes disorganised
  • barrier function weakens

👉 Result: moisture escapes more easily and irritants penetrate faster

2. Transepidermal Water Loss (TEWL) Increases

TEWL is the natural loss of water from your skin into the air.

In low humidity environments:

  • the gradient between skin and air increases
  • water evaporates faster

When the barrier is weakened, TEWL rises even more.

👉 Result:

  • dehydration
  • sensitivity
  • flare-ups

3. Natural Moisturising Factors Decrease

Cold weather slows the enzymes that produce compounds that help your skin retain water.

👉 Result:

  • reduced water retention
  • rougher skin texture
  • increased dryness

4. Temperature Changes Trigger Inflammation

Moving between cold outdoor air and heated indoor spaces causes:

  • rapid blood vessel constriction and dilation
  • increased inflammatory signalling

👉 Result:

  • redness
  • flushing
  • sensitivity

5. Eczema, Psoriasis and Rosacea Get Worse

These conditions already involve a compromised skin barrier.

Winter amplifies this by:

  • increasing TEWL
  • reducing lipid availability
  • allowing irritants to penetrate more easily

👉 Result:

  • itching
  • inflammation
  • more frequent flare-ups

What Dermatologists Recommend for Winter Skin

Focus on Barrier Repair (Not Just Hydration)

Hydration alone isn’t enough.

You need to:

  • replenish lipids
  • reduce water loss
  • protect the barrier

Simplify Your Skincare Routine

Overloading your skin with actives can worsen barrier damage.

Instead:

  • fewer products
  • gentle formulations
  • consistent routine

Use Barrier-Supportive Moisturisation

Winter skin benefits from products that:

  • reduce TEWL
  • support lipid structure
  • protect the skin surface

Avoid Common Winter Mistakes

  • hot showers
  • harsh cleansers
  • over-cleansing
  • skipping moisturiser after bathing

Act Early (Before Flare-Ups Start)

Winter damage builds over time.

Daily support helps prevent flare-ups rather than reacting to them.

A Simple Winter Routine That Works

Step 1: Lock in moisture after showering

After bathing, water evaporates quickly from the skin.

👉 Use Peony After Shower Moisture Lock

  • helps reduce TEWL
  • seals hydration into damp skin
  • supports barrier function

 

Step 2: Strengthen your skin barrier daily

For skin prone to dryness or flare-ups:

👉 Use High Factor Peony Root Skin Remedy

  • supports lipid balance
  • calms inflammation
  • protects compromised skin

Step 3: Keep your routine consistent

Barrier repair depends on daily support—not occasional treatment.

Summary

Winter skin problems are driven by measurable biological changes:

  • increased transepidermal water loss
  • reduced lipid function
  • impaired barrier integrity

The most effective approach is simple:

👉 protect the barrier
👉 reduce water loss
👉 support skin consistently

 

FAQs About Winter Skin

Why does skin get drier in winter?

Skin becomes drier in winter because low humidity and cold temperatures increase transepidermal water loss (TEWL) and reduce lipid production in the skin barrier.

What is TEWL in skincare?

TEWL (transepidermal water loss) is the passive evaporation of water from the skin. Higher TEWL means your skin is losing moisture faster, leading to dryness and sensitivity.

Why does eczema get worse in winter?

Eczema worsens in winter because the skin barrier becomes weaker, allowing more water loss and easier penetration of irritants, which increases inflammation.

How can I protect my skin barrier in winter?

You can protect your skin barrier by:

  • using gentle products
  • applying moisturiser after bathing
  • avoiding hot showers
  • maintaining a consistent routine
