Your skin is often the first place to show how healthy you really are. Have you suddenly noticed a dry patch, a dull complexion or wounds that are slow to heal? This can sometimes be simply due to cold weather, stress or a short night's sleep, but your skin can also be signalling that your body is lacking certain nutrients. By listening more closely to your skin, you can learn a lot about what your body needs. In this article, we will take you through common skin complaints and the deficiencies that may be behind them.

Functions of your skin
Your skin is more than just a protective layer: it is your largest organ and a real multitasker. It protects you from bacteria, sunlight and harmful substances, helps regulate your body temperature and plays a role in the production of vitamin D. In addition, a healthy skin barrier ensures that moisture is retained and external irritants are less likely to cause problems.
Healthy skin usually looks supple and smooth, is elastic and has a natural glow. If this changes, it may be a sign of deficiencies or imbalances.
Deficiencies that your skin may show
1. Dry skin → Possible deficiency in omega-3 and vitamin E
Tight, dry skin can be more than just a reaction to winter air, air conditioning or heating. It is often a sign of something going on inside the body. Dry and flaky skin can indicate a deficiency in essential fatty acids, vitamin A or zinc. These deficiencies can weaken the skin barrier, making the skin more prone to dehydration and irritation. They can also lead to reduced sebum production, which contributes to dry skin.
Healthy fats, such as omega-3, help keep your skin supple and support the natural barrier that retains moisture. Vitamin E is also a powerful antioxidant that protects your skin from harmful external influences, such as air pollution or sunlight. If you don't get enough of it, your skin can feel dry, flaky or dull more quickly. Borage oil is also known to naturally support skin health, especially for dry skin.
Food sources:
- Omega-3: oily fish (salmon, mackerel, sardines), linseed, chia seeds, walnuts, algae oil
- Vitamin E: almonds, hazelnuts, sunflower seeds, spinach, avocado
- Zinc: oysters, beef, pumpkin seeds, cashew nuts
- Vitamin A: carrots, sweet potatoes, spinach, liver

2. Dull, lifeless skin → Iron or vitamin B12 deficiency
Skin that loses its natural glow and looks pale or tired may indicate an iron or vitamin B12 deficiency. Both nutrients are essential for the production of red blood cells, which transport oxygen throughout your body and to your skin. If this process is impaired, your skin receives less nourishment and oxygen, making it look dull and lifeless. This often goes hand in hand with other signs, such as fatigue, low energy or cold hands and feet.
Food sources:
- Iron: red meat, chicken, eggs, legumes, green leafy vegetables
- Vitamin B12: meat, fish, dairy products, fortified plant-based milk
Vitamin C helps improve the absorption of iron from plant sources, so combine spinach with peppers or oranges, for example.
3. Slow wound healing or cracks → Zinc or vitamin C deficiency
Small wounds, cracks or irritated areas should normally heal fairly quickly. If you notice that this takes longer for you, it may be due to a zinc or vitamin C deficiency. Zinc plays a crucial role in tissue repair and the production of new skin cells. Vitamin C supports the production of collagen, a protein that ensures skin firmness and elasticity. Together, they help keep the skin stronger and more resilient, allowing it to recover better from minor damage.
Food sources:
- Zinc: oysters, beef, pumpkin seeds, cashews
- Vitamin C: citrus fruits, kiwi, strawberries, bell peppers, broccoli
4. Pimples or troubled skin → Possible vitamin A or zinc deficiency
Troubled skin with pimples or inflammation can have many causes, such as hormones, stress or diet. However, deficiencies can also play a role. Vitamin A supports skin cell renewal and helps keep the skin in balance. Zinc contributes to the regulation of sebum production and supports the skin's repair process. If you don't get enough of these nutrients, your skin may be more prone to blemishes and take longer to repair itself.
Food sources:
- Vitamin A: carrots, sweet potatoes, spinach, liver
- Zinc: oysters, meat, nuts, seeds
5. Wrinkles or sagging → Possible deficiency in collagen-supporting nutrients
Early wrinkles or loss of skin elasticity can be a sign that your skin is producing less collagen. Vitamin C, proteins and antioxidants are important for building and protecting collagen. A deficiency can contribute to premature ageing of the skin.
Food sources:
- Vitamin C: citrus fruits, kiwi, bell peppers, broccoli
- Protein: meat, fish, eggs, legumes, tofu
- Antioxidants: berries, green tea, nuts
6. Red, irritated skin or eczema → Possible deficiency in essential fatty acids or vitamin D
A deficiency in omega-3 fatty acids or vitamin D may play a role in eczema or red, irritated skin. Essential fatty acids support the skin barrier and vitamin D helps regulate the immune system, which can reduce skin inflammation.
Food sources:
- Omega-3: oily fish, linseed, chia seeds, algae oil
- Vitamin D: oily fish, eggs, fortified products, sunlight
What else is important for healthy skin
What you eat is reflected in your skin. Radiant skin starts from within: sufficient vegetables, fruit, healthy fats and protein-rich foods contribute to radiant skin. In addition, hydration, sleep and stress management play a major role.
In some cases, supplements can be an important addition. For example, in cases of vitamin C, zinc, omega-3 or vitamin E deficiencies, or in cases of increased need due to stress, illness or skin problems such as acne, dry skin or slow wound healing. Supplements help to replenish these deficiencies, support the skin's natural functions and can enhance the effect of a healthy diet.
Conclusion
Your skin tells you more than you think: it is a mirror of your health and is often the first to show when there are deficiencies or imbalances. By paying attention to the signals your skin gives you and ensuring a good foundation of healthy nutrition, sufficient hydration and a balanced lifestyle, you not only support your skin, but your entire well-being. This way, you will radiate from the inside out.
