Key Takeaways
- Skin is the body's largest organ and is largely composed of water-filled cells, so dehydration directly impairs its function and appearance.
- When dehydrated, skin cells become less plump, causing dry texture, heightened wrinkle appearance, sunken eyes, and a more gaunt and aged look.
- The body prioritizes internal organs when water is scarce and pulls moisture from peripheral tissues like the skin, worsening surface dehydration.
- Drinking eight 8-ounce glasses of water daily helps maintain skin cell plumpness, which reduces the appearance of fine lines and supports a healthy glow.
- Staying hydrated works best as part of a comprehensive skin care routine that includes sunscreen, moisturizer, and professional treatments as needed.
We hear the advice everywhere, from the internet to our own doctors: drink more water. We should all be drinking eight, 8-ounce glasses of water every day in order to stay healthy. Along with the health benefits, drinking water is an essential part of having glowing, young-looking skin- but why? Lets discuss the reasons why drinking water is so important for your skin.
Your skin is the largest organ of your body. All your organs are made of cells, which are largely composed of water. As your cells lose water and it isnt replaced, they start to function less efficiently. In your skin, this translates in dry, itchy, tight sensations, and a heightened appearance of wrinkles. The skin cells are also less plump, which can in turn make you look more gaunt, and make your eyes and cheeks look more sunken. The net effect is that you look older than you are, and more tired, when youre dehydrated.
Your body will also pull water from your tissues (like your skin) when you are dehydrated in order to maintain the correct levels in your bloodstream. This exacerbates the problem of dry skin because it makes the skin even drier, more flaky, and more sunken.
Drinking eight glasses of water a day ensures that your internal organs and bloodstream are sufficiently hydrated, and not pulling water from your skin. It also sends water to your skin cells, plumping them up and increasing functionality, firmness, and elasticity.
You can increase the effect of proper hydration by using a moisturizer. Applying a moisturizer within two minutes of getting out of the shower is especially effective because your pores are still open and will more efficiently absorb the moisturizer you are applying. However, topical applications can only go so far if you are not ingesting the right amount of water for your body.

Frequently Asked Questions
Why is water so important for healthy-looking skin?
Skin is the body's largest organ and its cells are largely composed of water. When those cells lose water and it isn't replaced through adequate hydration, they function less efficiently, resulting in dry, tight, itchy skin with a heightened appearance of wrinkles and a more sunken, tired facial appearance.
How does dehydration make you look older?
Dehydrated skin cells are less plump than hydrated ones, which can make the face look thinner, more gaunt, and more wrinkled. The under-eye and cheek areas are particularly sensitive to dehydration, often appearing hollow or sunken when the body is not getting enough water.
How does the body prioritize water when you are dehydrated?
When the body lacks sufficient water, it pulls moisture from peripheral tissues, including the skin, to keep vital internal organs functioning. This means your skin is among the first areas to suffer the visible effects of dehydration, even before you may feel thirsty or unwell.
How much water should I drink daily for healthy skin?
The widely recommended guideline is to drink eight 8-ounce glasses of water per day. This helps maintain the plumpness of skin cells, supports the skin's natural barrier function, and contributes to an overall healthier, more radiant complexion.
Is drinking water enough to maintain healthy skin on its own?
Staying hydrated is essential but works best as part of a broader skin care routine. Sunscreen, moisturizer, and professional treatments like chemical peels or laser resurfacing address concerns that hydration alone cannot resolve. Combining good hydration with proper skin care gives you the best long-term results.
