Itchy skin is not only uncomfortable but also causes damage to the skin, and can be caused by many reasons. Below are skin diseases that cause itching and how to treat them.

Dry skin

Dry skin causes roughness, flaking, itching, but no rash. This condition can occur anywhere on the body, dry skin and itching on the face are more likely in cold, dry weather.

To remedy this, use a gentle cleanser and moisturizer containing ceramides. These help strengthen and restore the skin barrier, thereby preventing transepidermal water loss.

Eczema

Eczema is a chronic non-contagious skin disease, related to genetic factors, constitution, and contact substances. The disease causes lesions on the skin that are dry, red, and itchy. Eczema has many types such as nummular eczema, contact eczema, atopic eczema, which can appear in episodes, persistent or recurrent.

Moisturizers should be applied regularly to keep the skin hydrated. Patients should see a doctor for medication to control symptoms.

Seborrheic dermatitis

Seborrheic dermatitis appears in oily areas of the skin such as the T-zone (nose, forehead), behind the ears, eyebrows, neck and chest. Some manifestations include pinkish-red rash, scaly, greasy, itchy surface. According to the American Academy of Dermatology (AAD), anyone can be affected, but this condition occurs more in people over 50, especially men and people with dark skin.

The doctor prescribes topical medications to reduce the extent of skin damage. If the inflammation is severe and widespread, the patient is prescribed oral medications. In severe, prolonged cases where medication is ineffective, the doctor may treat with light therapy to clear the scales and improve the skin condition.

Contact dermatitis

If your skin is itchy and has a red rash that appears after using a new cleanser, soap, lotion, or cosmetic product, you may have contact dermatitis. It usually clears up within a few days to a few weeks of avoiding the irritant. During this time, you can apply a cool compress for 10-15 minutes at a time to relieve the itching or use a moisturizer.

Other causes

Sometimes itching on the face or other parts of the body is caused by taking new medications such as aspirin, blood pressure medications, pain relievers, or radiation therapy for cancer.
