Dry, itchy skin is a common problem that can affect anyone. While dry skin may have various causes, staying hydrated is often touted as an easy solution. But does drinking more water actually hydrate your skin and alleviate dryness? This article examines the link between drinking water and skin hydration.
We’ll look at whether ingesting water impacts skin moisture at all, healthy hydration practices, common causes of dry skin, and effective solutions for combating dryness. Read on to learn the facts about hydrating your skin from the inside out.
Does Drinking Water Hydrate Skin At All?
The notion that drinking extra water improves skin hydration is not entirely unfounded. Water makes up a significant portion of our body weight, and being in a state of dehydration can potentially cause dryness.
But does routinely drinking more water than needed provide hydrating benefits for the skin? According to scientific research, the answer is more complicated than a simple yes or no. While the body needs adequate water intake to function properly, there is little evidence that increasing water consumption leads to measurable improvements in skin hydration.
The few small studies that exist have had inconsistent results. Some found a minor benefit, while others found no difference in skin hydration between people who drank more versus less water daily.
Importantly, these studies focused on healthy people who already drank normal amounts of fluids daily. For those with a truly inadequate fluid intake, drinking more water can help return the body and skin to a normally hydrated state.
However, once properly hydrated, further increasing water consumption does not appear to confer additional skin moisture benefits.
This is because the fluid concentration in our bodies is under homeostatic control – meaning intake and losses are kept in balance through tightly regulated physiological mechanisms.
In reality, the outermost layer of the skin, known as the stratum corneum, contains very little fluid. It is comprised of dead skin cells and lipids that provide a barrier function. Therefore, skin hydration is influenced much more by the skin’s own barrier integrity and sebum production than the amount of water circulating in the body.
While essential for overall health, fluid intake has little direct impact on skin dryness according to the scientific literature.
For this reason, topical moisturizers are generally considered vastly more effective than drinking extra water to hydrate the skin.
Healthy Hydration Practices
While chugging glass after glass of water is unlikely to moisturize your skin, staying properly hydrated is still important for overall health.
Here are some tips for healthy hydration habits:
Drink when thirsty. Let your body’s internal cues guide your fluid intake.
💠Consume plenty of water and other unsweetened beverages like herbal tea. Avoid sugary drinks which can contribute to empty calories.
💠Eat hydrating foods like fruits and vegetables which have high water content.
💠Don’t wait until severely thirsty to drink. Carry a refillable water bottle for easy accessibility.
💠Choose beverages based on your needs. Sports drinks can replenish electrolytes lost during intense exercise.
💠Limit diuretics like caffeine and alcohol which can lead to dehydration.
Remember, unless medically advised to restrict fluids, there’s no set amount of water everyone needs daily. Healthy individuals who eat a normal diet typically get adequate hydration through normal eating and drinking habits.
What Causes Dry Skin?
While drinking more water doesn’t provide measurable skin moisturizing benefits, dryness is still a problematic skin condition for many. What causes this bothersome issue? Dry skin generally results from:
💠Disruption of the stratum corneum skin barrier – This outermost layer of skin keeps moisture in and irritants out. Harsh cleansers, over-exfoliation, and picking can damage this protective barrier and lead to water loss and dryness.
💠Reduced sebum production – Skin naturally lubricates itself with oil from sebaceous glands. Aging and other factors can decrease sebum production causing dryness.
💠Cold, dry air – Low humidity, especially in winter, draws moisture from the skin. Long hot showers can also deplete natural oils.
💠Sun exposure – UV radiation damages skin cells, thinning the stratum corneum.
💠Medications – Drugs like acne treatments, diuretics, and antihistamines can dehydrate skin as a side effect.
💠Underlying medical conditions – Diseases affecting organs like the kidneys, liver, and thyroid may result in dry skin.
💠Genetics – Some people are just predisposed to drier skin types.

Solutions For Dry Skin
If you’re suffering from dry, flaky skin the following tips can provide relief:
🔶Use gentle cleansers without harsh surfactants that can strip the skin. Avoid very hot showers.
🔶Apply thicker, oil-based moisturizers like OTC creams containing petrolatum, mineral oil, or dimethicone. These occlusive ingredients prevent water evaporation from the skin surface.
🔶Look for moisturizers, toners, and serums containing humectant ingredients like glycerin, hyaluronic acid, and panthenol to draw in hydration.
🔶Take shorter, lukewarm showers instead of long hot ones. Pat skin partially dry and apply moisturizer immediately after bathing to lock in water.
🔶Install a humidifier during dry winter months.
🔶Avoid overly vigorous scrubbing and use of drying acne treatments like benzoyl peroxide if not needed.
🔶Apply moisturizer frequently throughout the day. Very dry skin may require prescription creams with urea.
🔶If dryness persists see your doctor to rule out any underlying conditions. Prescription creams may be warranted for more severe cases.
Conclusion
Does drinking extra water hydrate your skin? Despite the pervasive belief that downing more H2O moisturizes skin, current scientific evidence does not support this claim. Consuming sufficient fluid is vital for overall health, but won’t counteract a damaged moisture barrier or other causes of dryness.
Sticking to healthy hydration habits and using topical skin treatments like moisturizing creams and ointments are your best bets for combating lackluster skin. While hydrating well is advisable, you likely don’t need copious amounts of water to achieve soft, supple skin.
Frequently Asked Questions
No, water intake has no direct effect on acne. Effective acne treatments are applied topically.
Fruits and vegetables with high water content like cucumbers, watermelon, tomatoes, and lettuce can contribute to skin hydration.
Adequate hydration promotes general health, which can have positive anti-aging effects. But drinking extra water doesn’t directly affect skin aging.
Increased water consumption does not decrease wrinkles. Moisturizers and retinoids are better anti-wrinkle treatments.
