What should you look for?

  • Fine lines become more visible as skin loses moisture.
  • Small flakes, scaling or peeling appear on the surface.
  • The texture feels rough rather than soft.
  • Dry patches look lighter or darker than your usual skin tone, or red to purple.
  • With severe dryness, cracks can become deep enough to bleed.

Appearance is only part of the picture. Dry skin can feel tight, and excessively dry skin can itch much of the time. Cracked or raw skin can hurt, sting or burn when touched, even by water. Dryness can affect a small patch or a larger area, including the face, hands and legs.12

Is dehydrated skin different from dry skin?

Dry skin lacks moisture in its outermost layer, called the stratum corneum, and can develop surface cracks. Excessively dry skin has lost enough moisture to be noticeably dehydrated. Dryness and dehydration describe overlapping signs, despite skincare vocabulary's enthusiasm for separate departments. A rough patch or visible fine lines alone cannot tell you why the skin has lost moisture; the symptoms and circumstances matter too.123

Low humidity in winter can make skin excessively dry. Some medicines can also cause severe dryness, including diuretics and statins. Frequent hand washing, outdoor work and cold or dry climates increase the risk of dry skin. If dryness starts after a medication change, mention that timing to your clinician rather than treating it as just a cosmetic change.24

What should you do about it?

Moisturizers are the main treatment for most dry skin: they soften the surface, help prevent cracking and support the skin's protective barrier. Moisturizers come as creams, lotions, ointments and oils, so the category has already held its naming meeting.2

  1. 1Choose a fragrance free moisturizer designed for the affected area, such as your face or body.
  2. 2Apply moisturizer after a shower or bath while your skin is still damp.
  3. 3Apply moisturizer again when you wake up and before bed.
  4. 4Arrange a dermatologist appointment if dryness does not go away or keeps returning.

When does skin need medical attention?

Seek medical care for painful, bleeding cracks or itch that disrupts sleep or daily activities. Yellow crusts, leaking pus or other fluid, swelling and discoloration are signs of a possible skin infection. Breaks in excessively dry skin allow germs to enter, so these changes need more than another application of moisturizer.1

Does dry skin mean your whole body is dehydrated?

Body dehydration means losing more fluid than you take in. Dry skin can accompany it, but look for other symptoms: thirst, a dry mouth, dark urine, urinating less, tiredness or dizziness. Sunken eyes can also occur. These symptoms call for fluid replacement, not just skincare. Start with small sips if nausea makes drinking difficult; a pharmacist can advise on oral rehydration solutions after vomiting or diarrhea.56

A skin pinch checks skin turgor, meaning how quickly skin returns to shape. Skin that stays raised or returns very slowly can indicate significant fluid loss. Elasticity can also change for reasons unrelated to body fluid, so a pinch is not a diagnosis of facial dehydration. Seek prompt medical help if slow return accompanies vomiting, diarrhea or fever, or you cannot drink enough.7

Get medical help immediately for dehydration with confusion, fainting, no urination, rapid breathing or a rapid heartbeat. Cold skin, difficulty breathing or being difficult to wake can signal shock and require emergency care.56
