Quick Answer
Dry skin, known medically as xerosis, is a very common condition where your skin lacks enough moisture. It causes a rough, scaly, and flaky texture, often accompanied by itching and fine cracking. You might notice your skin looking ashy or grey. Dry skin typically worsens during the winter months when the air is cold and dry, or as you get older. Managing it usually involves simple lifestyle adjustments, such as switching to lukewarm showers, using gentle cleansers, and applying a thick moisturiser immediately after bathing to lock in hydration.

Frequently Asked Questions
What does severe dry skin look and feel like?
Dry skin typically feels rough, tight, and itchy. You may notice flaking, peeling, or an overall scaly texture. On some skin tones, the affected areas might look ashy or grey. In more advanced stages, fine cracks can form, which may become deep enough to bleed. The condition often feels much worse immediately after a long, hot shower, especially during the cold winter months.
Why is my skin suddenly getting so dry?
A sudden onset of dry skin is often linked to environmental changes, such as a drop in humidity during winter or turning on indoor central heating. Other common culprits include taking long, steamy showers, using harsh bar soaps that strip natural oils, or general dehydration. As we age, our skin naturally loses its ability to retain moisture, and certain underlying medical conditions can also contribute.
What is the best daily routine to fix flaky skin?
The most effective habit is to apply a thick, fragrance-free moisturiser immediately after getting out of the shower while your skin is still slightly damp. This helps to lock the existing water into your skin. Switch to lukewarm water instead of hot, limit your bathing time to five or ten minutes, and use a mild, gentle cleanser rather than harsh soaps. Running a humidifier can also help.
Will dry skin eventually go away on its own?
Dry skin often requires active management to resolve, especially if you live in a dry climate or the condition is age-related. While it might improve naturally when the weather gets more humid, you usually need to make consistent changes to your bathing habits and moisturising routine to see a lasting difference. If you stop daily moisturising, the roughness and flaking will likely return.
When should I see a doctor about my dry skin?
You should consult a healthcare professional if your dryness is severe, painful, or does not improve despite using thick moisturisers regularly. Also seek medical advice if the dry skin is accompanied by intense itching that disrupts your sleep, widespread inflammation, open sores from scratching, or signs of an infection like oozing. These symptoms might indicate a condition requiring prescription treatment.
How do I know if it is just dry skin or eczema?
While both conditions cause dry and itchy patches, eczema often presents with more intense inflammation, severe redness or pigmentation changes, and extreme itching. Eczema usually flares up in specific areas like the insides of elbows or behind the knees. Simple dry skin usually responds well to heavy moisturisers, whereas eczema often requires targeted medical treatments, such as prescription topical creams, to calm the flare.
Does drinking more water cure dry skin?
It is a common myth that simply drinking more water will cure dry skin. While severe dehydration can certainly cause your skin to lose elasticity and moisture, increasing your water intake beyond standard, healthy levels will not automatically plump up a dry outer skin layer. Environmental factors, bathing habits, and topical moisturisers usually play a much more significant role in managing ordinary dry skin.
