Different types of rashes - Huntington NY Area

Rashes can be itchy, frustrating, and potentially embarrassing. The symptoms can impact your everyday life. There are many different types of skin rashes, and their causes and treatments may vary. At the Dermatology & Cosmetic Laser Center in Huntington, New York, we take the time to assess your condition to understand the underlying cause of your rash and determine the most appropriate treatment solution.

Different types of rashes

A rash typically refers to a red patch of skin. It may itch, be flat or raised, and can be located anywhere on the body. Rashes can stem from allergic reactions, medications, heat, infections, or immune system disorders. The most common rashes include eczema, psoriasis, and rosacea. Skin conditions should be assessed by a dermatologist to determine the exact cause. 

Symptoms and causes of common skin rashes

Eczema is a common skin condition involving red, itchy patches. Although it is commonly found in young children, older children and adults can be affected. Eczema is commonly caused by irritants or allergens, hay fever, asthma, or genetics. Symptoms of eczema can vary but may include the following:

  • Dry skin
  • Red patches
  • Itchiness
  • Patches of skin that are dark colored
  • Rough or scaly skin
  • Crusting
  • Swelling

Psoriasis is a chronic, autoimmune skin condition that impacts adults and children. In psoriasis, skin cell production occurs more rapidly than normal. Cells multiply and regenerate faster than the body can eliminate them, resulting in an excess of dry skin. Psoriasis may flare up and go away at random. Symptoms may include rashes, dry skin, or flaking skin. Common causes of this skin rash include stress, infections, medication, dry air, sun exposure, alcohol, or smoking. 

A patient with rosacea may look flushed or as though he/she has a facial rash or acne. Redness or small bumps may appear on the cheeks, chin, nose, or forehead. Additionally, blood vessels on the face may swell and become visible through the skin. Although the cause of rosacea is unknown, environmental factors and genetics contribute to the problem.
