How does dehydration show on face?

Quick Answers

Dehydration can show on the face in various ways, including:

  • Dry, flaky skin
  • Wrinkles and fine lines becoming more noticeable
  • Dark circles under the eyes
  • Sunken eyes
  • Dry, chapped lips
  • Dull, lackluster complexion

Water is essential for the health and appearance of the skin. When the body becomes dehydrated, it shows in the face first. The skin relies on water to stay supple, firm, and glowing. When water intake drops, the complexion becomes drier, tighter, and lackluster. Fine lines and wrinkles become more pronounced as the skin loses elasticity. Under eye bags and dark circles can also develop as circulation slows. Lips chap and crack without adequate moisture. Learning to recognize the facial signs of dehydration allows you to take action to restore a radiant, hydrated complexion.

What Causes Dehydration?

There are several potential causes of dehydration including:

Inadequate Fluid Intake

Not drinking enough water is a common reason for dehydration. The Institute of Medicine recommends women consume 2.7 liters (91 ounces) of total water daily and men an average of 3.7 liters (125 ounces). This includes water itself along with other beverages and food. If your fluid intake falls short, dehydration can develop.

Intense Exercise

During intense or prolonged exercise, fluid loss occurs through sweating. If this fluid is not sufficiently replaced, dehydration can occur. Athletes and those who complete marathons and triathlons must be diligent about hydration before, during, and after exercise.

Hot Weather

Sweating helps cool the body in hot weather. But excessive sweating can lead to fluid deficits if you do not drink enough water to compensate. Outdoor workers and athletes must be aware of hydration needs during heat waves.

Illnesses Involving Vomiting, Diarrhea and Fever

When the body is fighting an infection or illness, fluid losses increase. Vomiting and diarrhea both deplete fluid volume. Fevers cause increased sweating. These symptoms make it important to stay well hydrated with water and electrolyte solutions.

Age-Related Changes

As we get older, our sense of thirst declines. Older adults often do not get adequate fluid intake as a result. Certain medications like diuretics also increase urination frequency and fluid loss. These factors put seniors at higher risk for dehydration.

Air Travel

The low humidity level during air travel can lead to increased fluid losses. Restrictions on bringing liquids through airport security may also limit how much water travelers drink. Dehydration is a common complaint after long flights.

Facial Signs of Dehydration

When the body lacks sufficient water, it manifests in the skin. Here are some of the key ways dehydration shows in the face:

Dry, Flaky Skin

Hydrated skin looks dewy, smooth, and supple. When skin becomes dehydrated it loses elasticity and moisture. The surface becomes dry and tight. This leads to flaky, peeling skin that feels rough to the touch. Dry patches and scales can develop anywhere on the face including the cheeks, nose, chin and forehead.

Exaggerated Fine Lines and Wrinkles

Facial skin has less structure and firmness when dehydrated. This causes fine lines and wrinkles to become more pronounced and noticeable. Areas around the eyes, mouth, and forehead are most affected. Young people may notice new fine lines that disappear when hydration is restored.

Dark Undereye Circles

With dehydration, skin loses some fullness and may become darker in color. This causes shadows under the eyes to appear more prominent. Circles or bags under the eyes look puffier and darker when you are dehydrated. Increased wrinkling from dehydration also contributes to darkened hollows under the eyes.

Sunken Eyes

The eyes may appear deep set and sunken when dehydrated. This happens because the skin loses elasticity and volume with inadequate moisture. The fatty tissue underneath the skin also shrinks, contributing to a hollow look around the eyes. Sunken eyes are a classic sign of dehydration.

Chapped Lips

The lips are vulnerable to drying and cracking when dehydrated. This causes chapped lips with a rough texture and surface fissures. Flaky skin may develop around the lips and mouth. Without adequate moisture, the lips lose plumpness and may appear smaller or thinner.

Dull, Lackluster Complexion

Dehydrated skin loses its glow and radiance. The complexion develops a lackluster tone without the light reflective quality of well-hydrated skin. Instead of looking plump and refreshed, facial skin appears dull and almost grayish when dry.

Increased Facial Puffiness

While sunken eyes occur in some, others may experience increased facial puffiness and swelling. When the body lacks sufficient water, it responds by holding onto whatever moisture it can. This causes fluid retention and puffy skin, particularly around the eyes and cheeks.

Dry, Cracked Lips

Lips have very little oil and moisture compared to the rest of the face. They readily dry and crack with inadequate hydration. Symptoms range from dry, peeling lips to deep cracks and fissures. This can be painful and increase risk of infection. Keeping lips hydrated prevents damage.

Premature Aging

Chronic mild dehydration accelerates facial aging over time. Ongoing loss of elasticity causes sagging jowls and deep wrinkles. The drying effects of dehydration add more lines and crepiness. A lackluster, worn appearance develops. Proper hydration helps maintain a youthful face as you age.

Tight Facial Skin

Notice if your facial skin feels tighter when you smile or make expressions. Taut skin that resists normal movement is a sign of dehydration. The skin loses elasticity and moisture when the body lacks sufficient water. Drink more fluids if your face feels stiff and tight.

Treating Dehydration

Reversing dehydration improves both health and appearance. Here are tips for regaining hydration:

Drink More Water

Increasing daily water intake is key to restoring hydration. Carry a water bottle as a reminder to drink frequently throughout the day. Drink a full glass upon waking and before meals. Choose water over coffee, soda, and alcohol that act as diuretics.

Consume Hydrating Foods

Some foods have high water content to help hydrate the body. Options include cucumbers, watermelon, cantaloupe, strawberries, grapefruit, peaches, oranges, yogurt, broth-based soups, and oatmeal. Incorporate these hydrating foods into your diet.

Apply Hydrating Face Mists

Spritzing your face with a hydrating mist provides an instant moisture boost. Look for formulas containing humectants like glycerin and hyaluronic acid. Apply face mist throughout the day over makeup for a quick pick-me-up.

Use Hydrating Skincare Products

Use cleansers, serums, moisturizers, masks, and other products that infuse moisture into the skin. Key ingredients to seek include ceramides, plant oils, shea butter, glycerin, and hyaluronic acid. Apply a thick night cream to deeply hydrate facial skin while you sleep.

Address Dry Indoor Air

Heated and air-conditioned environments cause moisture loss from the skin. Use a humidifier in your home and office to counteract dry air. This simple step makes a big difference in skin hydration and comfort.

Exfoliate Away Flakiness

Slough off dull, dry surface cells with facial exfoliation. This reveals fresher skin underneath. You can use a scrub with round soft beads or a cleansing brush. Follow with a hydrating toner to restore moisture balance.

Hydration Goal Daily Intake
Basic hydration 8 cups (64 ounces)
Moderate activity 10-12 cups (80-96 ounces)
Intense exercise 12-16 cups (96-128 ounces)

This table provides general daily water intake goals based on your activity level. Customize your own needs based on climate, size, and health factors.

When to Seek Medical Care

While mild dehydration responds readily to increased water intake, severe dehydration requires medical treatment. Seek prompt care if you experience:

  • Rapid heartbeat
  • Fainting or dizziness upon standing
  • Extreme thirst
  • Very dark, concentrated urine
  • Confusion, disorientation
  • Lack of sweating despite heat exposure
  • Dry mouth and throat
  • Weakness or lethargy
  • Low blood pressure

Intravenous fluid replacement may be necessary to restore hydration in advanced cases. Lab tests help assess the severity and guide treatment.

Preventing Dehydration

Making hydration a priority in your daily routine helps prevent deficits:

  • Drink water routinely throughout the day
  • Carry a water bottle with you
  • Choose water instead of sugar-sweetened beverages
  • Eat hydrating fruits and vegetables
  • Limit caffeine and alcohol intake
  • Drink more before, during and after exercise
  • Be vigilant about hydration during hot weather
  • Humidify air in your home
  • Apply moisturizer to boost skin hydration

Pay attention to signs of inadequate hydration like thirst, headache, fatigue, and dry or flaky skin. Increase fluid intake at the first hint your water levels are too low. Keeping the body well hydrated has huge benefits for both health and appearance.


Dehydration readily shows in the face. Dry, lackluster skin with more pronounced wrinkles and dark under eye circles indicate water deficits. Chapped lips, sunken eyes, and tightness in the skin are other telling facial signs. Boosting water intake counters dehydration to restore a supple, glowing complexion. Drinking adequate fluids daily is the best way to maintain great skin texture and radiance.
