With cold air, harsh winds and the dry warmth of indoor heating, winter asks more of your skin than any other season. When your skin barrier is compromised, the consequences are felt immediately: tightness, dryness, redness and sensitivity. But with a targeted ritual and the right active ingredients to support skin barrier function, skin can be calmed, soothed and nourished.
 
Skin barrier support starts with nourishing ceramides and lipids, which play a critical role in reinforcing barrier function and restoring hydration. By strengthening this structure, skin becomes more resilient, better able to retain moisture and less prone to dryness and irritation.

Frequently Asked Questions

How do I know if I have a compromised skin barrier?
Plus
Minus

An impaired barrier underlies many common skin concerns — and its signs are often more recognisable than people realise. There are six tell-tale indicators to watch for:
1.      Dryness and dehydration  
2.      Redness, irritation and increased sensitivity  
3.     Uneven texture  
4.     Itching, stinging, or tight skin sensations 
5.     Excessive oiliness, blemishes and congestion  
6.     Increased sun sensitivity

Should I be using a richer moisturiser throughout winter?
Plus
Minus

If your skin is feeling drier, more dehydrated, irritated or reactive, it’s a strong indication that your skin barrier is compromised and needs additional nourishment. Incorporating a ceramide-rich formulation, such as #4 The Nourishing Crème helps restore suppleness and replenish lipids whilst supporting the skin’s barrier defence.

Should I change my skin routine during the cooler months?
Plus
Minus

Cold air, indoor heating and low humidity accelerate moisture loss and place additional demands on the skin barrier. Rather than overhauling your ritual entirely, consider adding ceramide- and lipid-rich formulations for added comfort: a richer moisturiser, a nourishing cleanser that doesn't strip the skin's natural lipids, and targeted treatment for any areas of particular dryness or sensitivity.

Do I still need to use SPF?
Plus
Minus

The visible effects of photoageing accumulate year-round, regardless of temperature or cloud cover. Wearing SPF daily—no matter the season—is essential in protecting skin against UV damage and maintaining a healthy glow. 

What should I do if I am experiencing itchiness, dryness, sensitivity or tightness?

These are classic signals of barrier disruption, and the response should be targeted replenishment. Ceramides and lipids play a critical role in reinforcing barrier function and restoring hydration. By strengthening this structure, skin becomes more resilient, better able to retain moisture and less prone to irritation. 

What are the key active ingredients I should include in my routine?
