Dry skin isn't usually serious, but it can be uncomfortable and unsightly. Fortunately, most dry skin is caused by environmental factors that can be at least partially controlled. These factors include hot or cold weather, low humidity, and soaking in hot water. (Serious dry skin conditions — an inherited group of disorders called ichthyosis — should be evaluated by a physician or health care provider.)
The good news: you can do a lot on your own to improve your skin, including using moisturizers and avoiding harsh, drying soaps.
Let's start with the symptoms of dry skin. Dry skin is often temporary — you get it only in winter, for example — but it may be a lifelong condition. Signs and symptoms of dry skin depend on your age, your health, where you live, time spent outdoors and the cause of the problem. Dry skin is likely to cause one or more of the following:
- A feeling of skin tightness, especially after showering, bathing or swimming
- Skin that feels and looks rough
- Itching (pruritus)
- Slight to severe flaking, scaling or peeling
- Fine lines or cracks
- Gray, ashy skin
- Deep cracks that may bleed
When to see a doctor. Most cases of dry skin respond well to lifestyle and home remedies. See your doctor if:
- Your skin doesn't improve in spite of your best efforts
- Dry skin is accompanied by redness
- Dryness and itching interfere with sleeping
- You have open sores or infections from scratching
- You have large areas of scaling or peeling skin
Anyone can develop dry skin. But you may be more likely to develop the condition if you:
- Are in your 40s or older. The risk increases with age — more than 50 percent of older adults have dry skin.
- Live in dry, cold or low-humidity climates.
- Have a job that requires you to immerse your skin in water, such as nursing and hairstyling.
- Swim frequently in chlorinated pools.
So, what causes dry skin. Most dry skin (xerosis) is caused by an environmental issue. Certain diseases also can significantly affect your skin. Potential causes of dry skin include:
- Weather. Skin tends to be driest in winter, when temperatures and humidity levels plummet. But the season may not matter as much if you live in desert regions.
- Heat. Central heating, wood-burning stoves, space heaters and fireplaces all reduce humidity and dry your skin.
- Hot baths and showers. Taking long, hot showers or baths can dry your skin. So can frequent swimming, particularly in heavily chlorinated pools.
- Harsh soaps and detergents. Many popular soaps, detergents and shampoos strip moisture from your skin as they are formulated to remove oil.
- Other skin conditions. People with skin conditions such as atopic dermatitis (eczema) or psoriasis are prone to dry skin.
Dry skin is usually harmless. But when it's not cared for, dry skin may lead to atopic dermatitis (eczema). If you're prone to develop this condition, excessive dryness can lead to activation of the disease, causing redness, cracking and inflammation. Dry skin may crack, allowing bacteria to enter, causing infections. Complications are most likely to occur when your skin's normal protective mechanisms are severely compromised.
So what can you do to help prevent dry skin? Try these tips to keep skin from getting excessively dry:
- Moisturize. Moisturizer seals skin to keep water from escaping.
- Limit water exposure. Keep bath and shower time to 10 minutes or less. Turn the dial to warm, not hot. Try to bathe no more than once a day.
- Skip the drying soap. Try cleansing creams, gentle skin cleansers and shower gels with added moisturizers.
- Cover as much skin as possible in cold weather. Winter can be especially drying to skin, so be sure to wear a scarf, hat and gloves when you go out.
- Wear rubber gloves. If you have to immerse your hands in water or are using harsh cleansers, wearing gloves can help protect your skin.
