A red, itchy rash appears where the substance landed. We've put together this "Easy Guide to Treating Skin Allergy" so you can prevent, combat, and cure Sensitive and irritated skin.

Skin Allergy: Causes and Treatments



Rashes are characterized by changes in the color, feel, or texture of your skin.


Alternative Names

Skin redness or inflammation; Skin lesion; Rubor; Skin rash; Erythema; Skin Allergies; Skin Irritants



The appearance and symptoms of a rash can often reveal the cause. Skin testing, such as a biopsy, can also aid in diagnosis. Sometimes the cause of the rash is unknown.


What Causes Skin Allergies?

It takes at least 10 days after your first contact with something to become sensitive to it. You might even be able to touch something for years before becoming allergic to it. Dermatitis, which means skin inflammation, refers to a simple rash.

But once you develop an allergy, you could have a reaction within a few minutes of coming into contact with it. Or it might take a day or two.


The most common causes of skin allergies include:

  • Nickel, a metal used in jewelry and snaps on jeans, makeup, lotions, soaps, and shampoos
  • Sunscreens and bug sprays
  • Medications you put on your skin, like antibiotics or anti-itch creams
  • Fragrances
  • Cleaning products
  • Plants, including poison ivy
  • Latex, which is used in stretchy things like plastic gloves, elastic in clothing and balloons
  • Chemicals


Seborrheic dermatitis is a rash that appears as red and scaling patches around the brows, eyelids, mouth, nose, trunk, and behind the ears. If it occurs on the scalp, it is known as dandruff in adults and cradle cap in infants.

This harmless but bothersome condition is exacerbated by age, stress, fatigue, weather extremes, oily skin, infrequent shampooing, and alcohol-based lotions.

Other common causes of a rash include:

  • Eczema (atopic dermatitis) -- Tends to happen in people with allergies or asthma. The rash is generally red, itchy, and scaly.
  • Psoriasis -- Tends to occur as red, scaly, patches over joints and along the scalp. It is sometimes itchy. Fingernails may also be affected.
  • Impetigo -- Common in children, this infection is from bacteria that live in the top layers of the skin. It appears as red sores that turn into blisters, ooze, then for a honey-colored crust over.
  • Shingles -- A painful blistered skin condition caused by the same virus as chickenpox. The virus can lie dormant in your body for many years and re-emerge as shingles. It usually affects only one side of the body.
  • Childhood illnesses such as chickenpox, measles, roseola, rubella, hand-foot-mouth disease, fifth disease, and scarlet fever.
  • Medicines and insect bites or stings.

Many medical conditions can cause a rash as well. These include:

  • Lupus erythematosus (an immune system disease)
  • Rheumatoid arthritis, especially the juvenile type
  • Kawasaki disease (inflammation of the blood vessels)
  • Certain body-wide (systemic) viral, bacterial or fungal infections


Home Care (How You Can Treat Skin Allergy at Home)

The majority of simple rashes will improve with gentle skin care and avoidance of irritating substances. Follow the following general guidelines:

  • Avoid scrubbing your skin
  • Use gentle cleansers
  • Avoid applying cosmetic lotions or ointments directly on the rash.
  • Use warm (not hot) water for cleaning. Pat dry, don't rub.
  • Stop using any recently added cosmetics or lotions.
  • Leave the affected area exposed to the air as much as possible.
  • Try calamine medicated lotion for poison ivy, oak, or sumac, as well as for other types of contact dermatitis.

Hydrocortisone cream (1%) is available without a prescription and may soothe many rashes. Stronger cortisone creams are available with a prescription. If you have eczema, apply moisturizers over your skin. Try oatmeal bath products, available at drugstores, to relieve symptoms of eczema or psoriasis. Oral antihistamines may help relieve itchy skin.
