Quick version
Dry skin in winter is often caused by cold and dry air, indoor heat, hot water and reduced sunlight. This affects the skin's natural protective barrier and can lead to itching, irritation and flaking. In addition to using moisturizing skin care products, you can strengthen your skin by:
- Adjusting the indoor climate with a humidifier and lowering the temperature at night
- Drinking enough water every day
- Eating a nutritious diet with omega-3, antioxidants, vitamins A, E and D
- Protecting your skin from cold and wind with clothing and barrier creams
- Taking vitamin D supplements during the winter months if you are getting too little through the sun and diet
A holistic approach where you combine external skin care with internal nutrition gives the best results in preventing and relieving winter dry skin.
Why does skin become dry in winter?
The skin’s protective barrier is affected when temperatures drop and humidity levels decrease. As a result, the skin retains less moisture and the risk of irritation, itching, and flaking increases. Here are some factors that affect our skin health:
- Cold and dry outdoor air: these conditions dry out the skin and affect the lipid layer that normally protects against moisture loss.
- Indoor heating: air becomes drier due to radiators, underfloor heating, and air conditioning, which are used more frequently during winter – especially in bedrooms and office environments.
- Hot water: showers or baths can have a negative effect, as hot water strips the skin of its natural oils.
- Reduced sweat production: during winter, this can lead to a buildup of dead skin cells on the surface.
- Less sunlight: and lower levels of Vitamin D and other vitamins can indirectly affect the condition of the skin.
What can you do – beyond a good skincare routine?
Using moisturising creams is of course important – but there are additional ways to support the skin at a deeper level. Here are five effective steps you can start with today:
1. Review your indoor climate
Using a humidifier can be beneficial, especially in the bedroom, and slightly lowering the temperature at night can help, as the skin recovers better in cooler environments.
2. Drink enough water
Many people drink less water in winter than in summer, which can affect the skin’s moisture balance. Aim to stay well hydrated by drinking around 1.5–2 litres of water per day.
3. Eat a moisturising and vitamin-rich diet
Diet plays an important role in skin health. Focus on nutrients that strengthen the skin barrier. In addition to vitamin D, which you can get from supplements or fatty fish such as salmon, consider the following:
- Omega-3: from fatty fish, chia seeds, flaxseeds, and walnuts helps the skin retain moisture.
- Antioxidants: from berries, spinach, tomatoes, and kale protect the skin from oxidative stress.
- Vitamin A: supports cell renewal and strengthens the skin barrier. Found in carrots, sweet potatoes, and eggs.
- Vitamin E: protects skin cells and improves moisture balance. Found in avocados, nuts, and vegetable oils.
4. Protect your skin outdoors
- Use a scarf or neck gaiter over your cheeks and mouth to reduce the impact of cold wind.
- Apply a moisturiser with protective ingredients (such as ceramides or shea butter) before going outside.
- Choose a gentle cleanser that does not further dry out the skin.
5. Top up on vitamin D during the winter months
Vitamin D is important for both skin health and immune system function. During winter, sunlight is not a sufficient source in Sweden, and many people have lower-than-optimal levels without them being low enough to be classified as Vitamin D deficiency.
- Consider a vitamin D supplement, preferably in combination with omega-3.
- Vitamin D may help the skin maintain its normal structure and res
