As the cold weather rolls in, so too do the stories around winter skincare. You've probably already seen a handful of videos from content creators detailing the specifics of their new winter skincare routines. You likely also have a few friends that make a complete switch the moment we cross the cold-weather threshold.

Before you write this off as a mindless TikTok trends, there is some real and evidence-based merit to having a winter-specific routine. "Just as we adjust our wardrobe for the weather, our skincare should evolve too," says Dr Tanya Unni, holistic physician and skin doctor. We spoke with Dr Unni on all things skin health and changing seasons to understand more about why our winter skincare is a category of its own.

The fact of the matter is that your skin changes with the seasons, and so should the way you care for it. We dive into the details below.

Your skin behaves differently in winter – especially if you're in high altitudes or living in-land

Your skin is actually the biggest organ of the body. It's an intelligent one too.It tries to adapt and keep your body protected from external and environmental aggressors. But sometimes changes in weather and environment throw off the balance.

"Our skin responds directly to changes in temperature, humidity and environmental stressors. In winter, lower humidity and colder air can weaken the skin barrier, leading to increased dryness, sensitivity and dehydration," says Dr Unni.

These environmental factors can be even more pronounced in areas that are far in-land or places with a high altitude. "Inland and high-altitude regions tend to have lower humidity levels, which can accelerate moisture loss from the skin. Wind exposure and temperature extremes can further compromise the skin barrier and increase dryness," she says.

Do you really need to change your routine as a result?

When I asked Dr Unni if skincare routines should change for winter, her answer was clear: "definitely".

Since seasonal changes affect the specific needs of our skin, it's important to make small adjustments can help maintain a healthy, balanced complexion year-round. These changes can be more pronounced depending on your skin type too.

"Dry and sensitive skin types often need more intensive hydration and barrier repair during winter, while oily skin may simply require lighter adjustments. The key is listening to what your skin is telling you," says Dr Unni.

If your skin isn't getting what it needs, it will find a way to tell you. Itchiness and flaking are just some of the symptoms. Some people can even become more breakout prone as the skin overproduces oil to compensate for the dryness.

"The skin may become dry, tight, flaky, itchy or more sensitive than usual. Some people also notice increased redness, irritation or dullness. These are often signs that the skin barrier needs extra support and hydration," she says.

So, what does an ideal skincare routine looks like for the winter months?

There is no one ideal product for everyone as we have different skin types and sensitivities. But there are some key themes.

"A gentle cleanser, a hydrating serum, a nourishing moisturiser and daily sunscreen. At night, I recommend focusing on repair and hydration with ingredients that support the skin barrier and help lock in moisture.

"Don’t forget that winter sun can still cause significant skin damage, so sunscreen remains essential every day. Staying hydrated, maintaining a balanced diet, avoiding excessively hot showers and using a humidifier indoors can also make a noticeable difference to skin health."

Dr Unni in particular called out winter as the perfect time to switch to richer moisturisers and more nourishing serums. In terms of specific, look out for  ingredients ceramides, hyaluronic acid, glycerin and peptides – all of these are compounds that can help strengthen and hydrate the skin.

"I would add a barrier-supporting moisturiser and, if needed, a hydrating serum. I wouldn’t necessarily remove active ingredients completely, but I would be cautious about overusing exfoliants or harsh treatments if the skin is feeling sensitive or dry."
