What Causes Dry Skin?
Dry skin is an uncomfortable condition marked by scaling, itching, and cracking. It can occur for a variety of reasons. You might have naturally dry skin. But even if your skin tends to be oily, you can develop dry skin from time to time.
Dry skin can affect any part of your body. It commonly affects hands, arms, and legs. In many cases, lifestyle changes and over-the-counter moisturisers may be all you need to treat it. If those treatments aren’t enough, you should contact your doctor.
Exposure to dry weather conditions, hot water, and certain chemicals can cause your skin to dry out. Dry skin can also result from underlying medical conditions.
Dermatitis is the medical term for extremely dry skin. There are several different types of dermatitis.
Contact dermatitis develops when your skin reacts to something it touches, causing localized inflammation.
Irritant contact dermatitis can occur when your skin’s exposed to an irritating chemical agent, such as bleach.
Allergic contact dermatitis can develop when your skin is exposed to a substance you’re allergic to, such as nickel.
Seborrheic dermatitis occurs when your skin produces too much oil. It results in a red and scaly rash, usually on your scalp. This type of dermatitis is common in infants.
Atopic dermatitis is also known as eczema. It’s a chronic skin condition that causes dry scaly patches to appear on your skin. It’s common among young children.
Dry skin can affect anyone. But some risk factors raise your chances of developing dry skin, including:
- Age. Older adults are more likely to develop dry skin. As you age, your pores naturally produce less oil, raising your risk of dry skin.
- Medical history. You’re more likely to experience eczema or allergic contact dermatitis if you have a history of these conditions or other allergic diseases in your family.
- Season. Dry skin is more common during the fall and winter months, when humidity levels are relatively low. In the summer, higher levels of humidity help stop your skin from drying out.
- Bathing habits. Taking frequent baths or washing with very hot water raises your risk of dry skin.
Your doctor’s recommended treatment plan will depend on the cause of your dry skin.
In some cases, they may refer you to a skin specialist or dermatologist. Along with lifestyle remedies, they may recommend over-the-counter or prescription ointments, creams, or lotions to treat your symptoms.
Simple lifestyle changes can help prevent and relieve dry skin. Try to:
- avoid using hot water to bathe or shower
- shower every other day instead of every day
- keep your shower time to less than 10 minutes
- use a moisturising soap when you bathe or shower
- apply moisturiser immediately after bathing or showering
- pat, rather than rub, wet skin dry with a soft towel
- avoid itching or scrubbing dry skin patches
- use a humidifier in your home
- drink plenty of water
It’s also important to choose the right kind of moisturiser for your skin type.
If you experience occasional dry skin, you can likely prevent and treat it using simple lifestyle changes and good quality moisturisers. If you develop severe dry skin, make an appointment with your doctor.
If left untreated, dermatitis can get worse. Early treatment will help you to feel comfortable sooner. It will also lower your risk of complications, such as open wounds from scratching and skin infections.
