Contact Dermatitis Q & A


What is contact dermatitis?

Contact dermatitis is a condition that causes allergic reactions to substances that irritate the surface of your skin when in contact with it. Contact dermatitis typically causes skin reactions within 48-96 hours after exposure to irritating substances. The condition may develop at any time, regardless of age or life stage.


Which substances may cause contact dermatitis reactions?

Depending on what you’re allergic to, the following substances may cause contact dermatitis reactions:

  • Certain soaps
  • Rubber gloves
  • Solvents
  • Hair products
  • Bleaches
  • Detergents
  • Airborne substances
  • Pesticides
  • Fertilizers
  • Poison ivy or other plants 
  • Metals
  • Medications
  • Perfumes
  • Oral health products
  • Formaldehyde
  • Dyes
  • Cosmetic products

Children may develop allergic reactions after exposure to baby wipes, diapers, jewelry, clothing, or dyes. 


What are the symptoms of contact dermatitis?

Symptoms that may develop due to contact dermatitis include:

  • Red, itchy skin
  • Inflamed skin
  • Blisters
  • Tenderness
  • Burning
  • Rash
  • Hives
  • Scaly, dry, or cracked skin
  • Oozing 
  • Crusting

Symptoms might appear immediately, soon after exposure, later the same day, or within a few days. Such symptoms may be mild, moderate, or severe.


How is contact dermatitis diagnosed?

To determine if you have contact dermatitis and which substances you’re allergic to, the experts at Advanced Allergy, Asthma, & Immunology Center PA - Dr. Patricia Gomez Dinger discuss your symptoms, medical history, lifestyle, and more. They complete a physical exam and patch testing. 

During the test, your specialist places patches with allergens on your skin, leaves them there for 48 hours, removes the patches, and examines your skin to look for signs of an allergic reaction. They then customize your treatment plan. 


How is contact dermatitis treated?

Treating contact dermatitis may involve making lifestyle changes, scrubbing your skin with soap and water after exposure to allergens, and using prescribed creams, ointments, or oral medications. You can also avoid exposure to certain substances that cause skin irritation. 

Your specialist may suggest you avoid using irritating skin care products, other personal hygiene items, dyes, certain clothing materials, and some metals. Replace these items with others that don’t cause painful rashes on your skin.
