Staying hydrated matters for your health, but extra glasses of water won’t transform your skin on their own.
The gist
- Your body needs enough fluid to work well, but there’s limited evidence that extra water improves skin in healthy people.
- Dry skin is more often linked to weather, hot showers, harsh cleansers, age and genetics.
- Moisturizer applied to damp skin is one of the most effective ways to relieve dryness.
- Water and other unsweetened drinks are good everyday choices for your overall health.
“Drink more water” is one of the most common pieces of beauty advice. Hydration matters for your health, but its link to how your skin looks is weaker than many people think.
What the evidence says
Your body needs enough fluid to function, and serious dehydration can affect your skin. But for healthy people who already drink enough, there’s limited evidence that extra water makes a visible difference. The outer layer of your skin is affected more by your environment and your skincare routine.
What usually causes dry skin
| Cause | What helps |
|---|---|
| Cold, dry or windy weather | A richer moisturizer; a humidifier indoors |
| Long, hot showers | Shorter showers with warm water |
| Harsh soaps or cleansers | Gentle, fragrance-free cleansers |
| Age | More moisturizer, as skin makes less oil over time |
| Some skin conditions | Treatment from a dermatologist |
Habits that help dry skin
- Keep showers and baths short, and use warm rather than hot water.
- Apply moisturizer within a few minutes of washing, while your skin is still slightly damp.
- Choose creams or ointments over lotions if your skin is very dry.
- Use a humidifier when indoor air is dry.
Beauty tip
Keep a moisturizer by the sink so you can use it right after washing your hands or face. For many people with dry skin, that small habit makes a noticeable difference.
Hydration still matters
Even if water isn’t a skincare miracle, drinking enough supports your overall health. Water and other unsweetened drinks are simple everyday choices and a better habit than sugary drinks.
Worth remembering
See a doctor if you have very dry, cracked, itchy or bleeding skin that doesn’t improve with moisturizer. It may be a sign of eczema or another condition that needs treatment.
Focus on what works
For dry or dull-looking skin, a simple skincare routine, daily sunscreen and good sleep, covered in our guide to sleep and skin, are more reliable than extra glasses of water.
You asked
How much water should I drink?
Needs vary with your size, activity level and the weather. A simple guide is to drink enough that you rarely feel thirsty and your urine is pale yellow.
Can drinking water clear acne?
There’s no good evidence that drinking more water clears acne. Acne usually needs a consistent skincare routine and sometimes medical treatment.
Do face mists hydrate my skin?
They can feel refreshing, but water evaporating from your skin can leave it feeling drier. Follow with a moisturizer if your skin is dry.
