The combination of less sunlight, cold winds, and heating can cause chapped, dry skin in winter. Your skin barrier weakens, and you may also be more susceptible to inflammation. There's often an increased focus on external hydration by applying extra cream or oil, while your skin actually needs support from within.

The influence of omega-3 on the skin

Omega-3 fatty acids are essential fats that your body can't produce on its own. In winter, you'll want to get enough of them because they play a significant role in preventing dull skin.

1. Reduces inflammation and redness

Cold outdoor air and dry indoor air can irritate and damage your skin. This can cause redness, tightness, or sensitivity, and can lead to increased inflammation. Omega-3 has powerful anti-inflammatory properties and helps soothe your skin. Perfect if you suffer more from sensitive skin, rosacea, or eczema in the winter. Read more tips for dry skin here.

2. Strengthens the skin barrier and prevents dryness

Your skin acts as a shield against harmful influences, keeping unwanted substances and bacteria out. Winter conditions can weaken this barrier. Omega-3 supports the development of a strong skin barrier, allowing your skin to retain moisture better and stay protected from the cold and wind. This results in smoother, less dry skin.

3. Protects against premature aging

Cold and temperature fluctuations can cause additional oxidative stress in the skin, which breaks down collagen and makes wrinkles appear more quickly. Omega-3 acts as a powerful antioxidant and protects your skin cells from this damage.

Vitamin C also plays a crucial role here, as it's necessary for collagen production and helps combat free radical damage. Astaxanthin can be a great addition, as it's one of the most powerful antioxidants for your skin. This helps keep your skin firm and your glow intact.

4. Helps with oily skin and blemishes

It may sound counterintuitive, but omega-3s also help with acne and oily skin. They regulate sebum production, reducing clogged pores. In winter, your skin often reacts to temperature fluctuations by producing more sebum, which can cause breakouts. Omega-3s help balance this out.

Vitamin D and the skin

In summer, the sun gives us all radiant, hydrated skin. But in winter, our vitamin D production declines, and that affects not only our immune system, mood, and energy levels, but also our skin.

1. Stimulates cell renewal and repair

Vitamin D plays a major role in the production and repair of your skin cells. A deficiency can lead to dull, gray skin and slower wound healing. Adequate vitamin D ensures fresher, healthier skin that heals faster.

2. Supports the skin barrier

A strong barrier is essential for healthy skin. Like omega-3, vitamin D helps keep your skin firm and resilient, reducing the risk of bacteria and fungi. This is especially important in winter, when your skin is more vulnerable.

3. Keeps your skin young and hydrated

Vitamin D also helps your skin retain moisture and protect against free radical damage. This keeps your skin supple, firm, and well-hydrated, even when it gets cold.

How do you get enough omega-3 and vitamin D?

To optimally nourish your skin, it's important to consume these nutrients regularly. The best dietary sources are:

  • Omega-3: oily fish such as (wild) salmon, mackerel, herring, sardines.
  • Vitamin D: Also found in oily fish, but also in eggs or (to a lesser extent) in mushrooms.

Unfortunately, in the Netherlands, we don't eat enough oily fish to get enough omega-3 and vitamin D. To ensure your skin remains protected, you can supplement your diet with supplements.

Supplement with the right supplements

Want to make sure your skin gets everything it needs?

The Daily Essential Bundle contains omega-3 and vitamin D, plus zinc and magnesium. Two minerals that are also important for healthy, radiant skin.

This combination not only supports your skin, but also your energy, immune system and overall well-being.

Finally

Beautiful, healthy skin starts from within. By getting enough omega-3 and vitamin D, your skin gets the nutrients it needs to shine through the winter. Of course, it's also nice to pamper your skin with a nice facial cream or oil, but be sure to supplement with foods that nourish your skin from within.
