Dry skin

Dry skin makes the skin look and feel rough, itchy, flaky or scaly. It's a common condition that affects people of all ages. The medical term for dry skin is xerosis.

Dry skin has many causes. Examples include cold or dry weather, sun damage, harsh soaps, and too much bathing.

You can do a lot on your own to improve dry skin. Self-care steps include moisturizing, choosing products that are gentle on your skin and protecting your skin from the sun. You may need to try a number of products and skin care routines to find what works best for you.

Symptoms of dry skin can include:

• A feeling of skin tightness.
• Skin that feels and looks rough.
• Itchiness.
• Slight to severe flaking. This causes the ashy look that can affect dry brown and Black skin.
• Scaling or peeling.
• Fine lines.
• Cracks in the skin, including deep cracks that may bleed.
• Skin that ranges from reddish on white skin to grayish on brown and Black skin.
• A feeling of pain, stinging or burning on the skin.

Dry skin happens because of water loss from the outer layer of skin. It might be caused by:

• Heat. Central heating, wood-burning stoves, space heaters and fireplaces all lower air humidity.
• Environment. Living in a climate that has low humidity raises the risk of developing dry skin.
• Too much bathing or scrubbing. Taking long, hot showers or baths or scrubbing your skin too much can dry the skin. Bathing more than once a day can remove the natural oils from your skin too.
• Harsh soaps and detergents. Many soaps, detergents and shampoos strip moisture from the skin because they are designed to remove oil.
• Other skin conditions. People with skin conditions such as atopic dermatitis or psoriasis are more likely to have dry skin. Atopic dermatitis also is called eczema.
• Medical treatments. Some people develop dry, thick skin after receiving treatment for cancer, having dialysis or taking certain medicines.
• Aging. As people age, the skin thins and makes less of the oils needed for the skin to hold water.

Anyone can develop dry skin. But you're more likely to develop the condition if you:

• Are older than 40.
• Live in climates that have low humidity.
• Have a job that requires you to put your hands in water often or use harsh soaps. Examples include nursing, hairstyling and dishwashing.
• Use your hands to work with cement, clay or soil.
• Have certain medical conditions, such as hypothyroidism, ichthyosis, diabetes or malnutrition.

Dry skin usually is harmless. But when it's not cared for, dry skin may lead to:

• Atopic dermatitis, also called eczema. If you're prone to developing atopic dermatitis, very dry skin may trigger the condition, causing a rash and cracking skin.
• Infections. Dry skin may crack, allowing bacteria to enter the body and cause an infection.

These health concerns are most likely to happen when the skin becomes so dry that it can't protect itself the way it typically does. For example, very dry skin can lead to deep cracks forming in the skin. Those cracks may open and bleed. That offers a way for bacteria to get into the body and cause an infection.

Try the following tips to help your skin hold in water.

Moisturize

Moisturizer seals in water to help keep the skin's protective barrier healthy. Use moisturizer throughout the day, especially on the hands. Before going outdoors, use a moisturizer that contains sunblock or a broad-spectrum sunscreen with an SPF of at least 30, even on cloudy days. Apply sunscreen generously and reapply every two hours. Use it more often if you're swimming or sweating.

Limit water exposure

Keep bath and shower time to 10 minutes or less. Use warm, not hot, water. Rinse and pat dry. Try to bathe or shower no more than once a day.

Use a gentle cleanser or allergen-free soap

Try a cleansing cream or shower gel instead of soap. Or use a moisturizing soap that doesn't have any fragrance or anything that can cause an allergic reaction. Those products are labeled noncomedogenic or hypoallergenic. Rinse thoroughly and pat dry. Apply a moisturizer while your skin is still damp.

Shave with care

Shaving can dry the skin. If you shave, use a lubricating agent before you start. Use a sharp blade, and rinse it with warm water after each stroke. When you're done, put moisturizer on your skin.

Cover as much skin as possible in cold or windy weather

Harsh weather can be especially drying to skin. Scarves, hats, and gloves or mittens help protect your skin when you're outdoors.

Wear gloves

Protect your hands when you're gardening, using harsh cleansers or doing other activities that can dry the skin.

Drink when you're thirsty.

Drink water or other noncaffeinated beverages each day to help keep all your body's tissues, including your skin, well hydrated.
