Rashes Q & A

What are rashes?

Rashes are red, irritated areas of skin that can be dry and itchy. They may even change the color of your skin. While some rashes subside on their own, many can become chronic disorders and break out unexpectedly. 

The double board-certified dermatologists at Pure Dermatology work with you to identify your triggers and develop a targeted treatment plan that meets your needs.


What causes rashes?

Cosmetics, dyes, fragrances, soaps, and poison ivy or oak can cause short-term rashes that usually resolve quickly with treatment. Many underlying skin conditions can also cause rashes, including:


Eczema is a chronic condition that causes red, itchy patches of skin. Also called atopic dermatitis, eczema can appear anywhere, but it commonly develops on the face, arms, legs, and trunk.


Psoriasis looks similar to eczema, but lesions are typically shiny and waxy. As an autoimmune disease, psoriasis is usually a lifelong condition that requires ongoing management.


Cellulitis is a bacterial skin infection that causes redness, swelling, pain, and pus-filled blisters. The affected skin may appear tight and shiny.


Shingles is a painful inflammatory rash that typically affects one side of the body. Caused by the same virus as chickenpox, shingles can cause long-term pain and discomfort without treatment.


Impetigo is a bacterial infection that usually affects children. It appears as red, swollen sores than can ooze.


Are there skin conditions that look like rashes?

Many skin conditions can resemble a rash, including:

  • Rosacea
  • Hives
  • Skin allergies
  • Vitiligo

Vitiligo is a chronic condition that causes the skin to lose pigment. It usually develops in patches and occurs when your body loses melanocytes, pigment-producing cells.


What are the treatments for rashes?

At Pure Dermatology, your dermatologist tailors your treatment toward your specific rash. The team also uses your skin type, medical history, and genetic makeup. After a comprehensive skin exam, your dermatologic team may recommend:

  • Hydrocortisone creams
  • Calamine lotion
  • Oral or topical antibiotics
  • Corticosteroids
  • Light therapy
  • Antihistamines

If you have a chronic condition, like eczema or psoriasis, your dermatologist works with you to help you avoid particular triggers.
