What is a skin rash?

A skin rash is a skin problem that causes dry and flaky skin. A skin rash occurs when the skin becomes red, inflamed, and itchy. Some skin rashes are dry and itchy, while others are painful. Skin rashes can be caused by many factors, including viruses, bacteria, allergens, and skin conditions such as eczema.

Almost everyone has experienced a skin rash at least once in their life. Extremely often, itching is sometimes felt or red, flaky skin appears for a while.

What causes a skin rash?


Skin rash is an almost daily occurrence. Healthy skin sheds an average of 30 to 40,000 dead cells a day, allowing new ones to form. When a skin rash occurs, too many skin cells begin to shed. When the oily and moist layer that covers the surface of the skin dries out, it flakes off. In addition to dryness, skin rashes can be caused by eczema, allergic rashes, psoriasis, or other conditions.

  • Contact dermatitis: This type of dermatitis occurs when your body reacts to a substance it doesn’t like. Many people are allergic to fragrances, preservatives, nickel (common in jewelry) and poison ivy. Common irritants include soaps, detergents, chemicals, and household cleaners.
  • Eczema: Eczema, also called atopic dermatitis, usually develops during infancy and usually resolves as the child grows. People with asthma or allergies are also more prone to eczema.
  • Hives: Urticaria, also called hives, causes raised, red, and itchy skin. If you have an allergic reaction to airborne allergens or insect bites, you may have hives. Sudden changes in temperature and some bacterial infections can also cause hives.
  • Psoriasis: This lifelong skin disease causes a thick, scaly rash. The rash usually occurs on the elbows, knees, lower back, scalp, and genitals. Psoriasis can be inherited.
  • Widespread: A skin rash is a common symptom of many common illnesses, including chickenpox, measles, molluscum contagiosum, and dryness.

Skin rash symptoms vary depending on the type and cause. The rash can develop in one area or all over the body. Symptoms of a skin rash include:

  • Redness and peeling of the skin
  • burning or stinging
  • Extreme hardness and crusting on the skin
  • Swelling and inflammation of the skin
  • Dry skin and excessive itching
  • Skin tingling and soreness

How does a skin rash go?


The first step in treating a skin rash begins with the skin restoring the moisture it needs. First of all, you can start treating a skin rash by drinking plenty of water and moisturizing your body. If you have an itchy skin rash, it’s in your best interest not to scratch the area and keep it away from water. In other cases, the cause must be found before the skin rash is treated. If the skin rash lasts longer than 7 days, looks red, and hurts, you should see a dermatologist.

How is a skin rash diagnosed?

Diagnosis can be difficult as many things can cause a skin rash. Your doctor will examine the rash, evaluate your symptoms, and find the cause of the rash. Sometimes, however, some tests are needed to find the cause of the rash.

  • Biopsy: Your doctor may take a small sample of your skin or other tissue to check for a virus or bacteria.
  • Allergy test: Allergy tests, such as prick tests and patches, detect allergens. The prick test is helpful in diagnosing hives, and the patch is helpful in diagnosing allergic contact dermatitis. In these tests, your doctor exposes your skin to small amounts of allergens and watches for reactions. You may only be tested for a few or a few allergens at a time. If the skin becomes red, swollen, or red, you have an allergy.
  • Blood tests: Some skin conditions can be caused by antibodies circulating in the blood and can be detected with blood tests. Other rashes may be a sign of another systemic disease, so blood tests are needed to check for damage to other organ systems.
