Why Is Your Skin So Dry?

Your skin is your body’s largest organ and it relies on moisture and healthy oils to stay smooth and elastic. When that balance is disrupted, the outer layer loses water faster than it can replace it. The result is roughness, flaking and sometimes itching or redness. ¹

Environmental changes, over-cleansing, diet and certain medications can all play a part. But the good news is that dry skin is one of the most treatable skin concerns once you know what’s behind it.

Common causes of dry skin

1. Cold weather and central heating

Dryness often strikes hardest during autumn and winter. The air outside becomes cold and low in humidity, while indoor heating strips away even more moisture. ² This combination pulls water from your skin, leaving it feeling tight and uncomfortable.

A simple fix is to add a humidifier at home and use a thicker, barrier-repair moisturiser before bed.

2. Harsh cleansers and overwashing

It might feel satisfying to wash your face often, but doing it too frequently or with foaming cleansers can damage your natural protective oils. ³ Without those oils, moisture escapes easily.

Opt for gentle, pH-balanced cleansers or creamy formulas that clean without stripping.

3. Not drinking enough water

Hydration starts from within. If you’re not drinking enough water throughout the day, your skin won’t have the moisture it needs to stay supple. Aim for steady sips rather than downing large amounts at once, which your body quickly flushes away.

4. Nutrient deficiencies

Your skin depends on several key vitamins and fatty acids to retain moisture and repair itself. When these are low, dryness can set in quickly. ⁴

Vitamin E helps protect cell membranes and maintain the skin’s natural barrier. ⁵
Biotin contributes to the health of skin, hair and nails by supporting keratin production. ⁶
Omega 3 fatty acids nourish from within and help regulate oil production. ⁷
Collagen keeps skin firm and hydrated by improving its structure and elasticity. ⁸

5. Hot showers and baths

Long, hot showers feel relaxing but they remove natural oils from the surface of your skin. Lukewarm water is better for daily washing and applying body lotion straight after bathing helps trap in moisture.

6. Underlying conditions

If your skin stays persistently dry even after using moisturisers and drinking enough water, conditions such as eczema, psoriasis or thyroid issues might be involved. ⁹ In that case it’s best to consult your GP or dermatologist for tailored advice.

How to bring back hydration

Start by keeping your skincare simple. Use a gentle cleanser, apply a rich moisturiser while your skin is still slightly damp and protect it daily with sunscreen.

Internally, nourish your skin with a diet rich in healthy fats and colourful fruit and vegetables. Foods like salmon, avocado and walnuts deliver omega 3s, while almonds and sunflower seeds supply vitamin E.

If your skin needs extra support, look for supplements that provide biotin, collagen, omega 3 and vitamin E in one easy formula. These nutrients help rebuild your skin barrier and reduce dryness from the inside out.

And don’t forget lifestyle habits. Get enough sleep, manage stress and avoid smoking, as these all affect your skin’s ability to stay hydrated and heal.

Dry skin is often a sign your skin barrier needs care, both inside and out. By pairing gentle skincare with nourishing foods and targeted supplements, you can restore comfort and glow naturally.

The key is consistency. Hydrate, feed your skin with the right nutrients and give it time to repair. Within a few weeks, you’ll likely notice smoother, softer and more radiant skin.
