Noninfectious skin rashes which are commonly seen are; Eczema, psoriasis, contact dermatitis, drug rash, Hives (Urticaria), pityriasis rosea (Christmas tree rash) and Heat rash (Miliaria).

  • Eczema (Atopic dermatitis)



Eczema (Atopic dermatitis) comes under chronic common skin rashes seen in children but also in adults. It is a long term disease and tends to have exacerbations (flares) and remissions (healed stage). Eczema can run in families and may associate with Hay fever and Asthma.

Eczema can be dry or wet. When it is dry there are red patches, thickened due to scratching. The area becomes scaly sometimes cracked and associated with dry skin. In wet eczema, there is oozing from lesions with crusting. There is a possibility of infection. The lesions are raw and angry looking. There is intense itching in eczema where sometimes your sleep can get disturbed.

Eczema usually starts in childhood and may continue to have flare-ups on and off throughout life. Continuous and habitual scratching can lead to thick, leathery and discolored lesions.


There is no cure for eczema however it can be controlled, but the disease can go in to complete remission anytime.

  • Moisturize your skin well with a good emollient regularly, especially to damp skin after a bath.
  • Avoid strong soaps and detergents which can worsen eczema
  • Apply over the counter medications like 1% Hydrocortisone cream or prescribed creams or ointments such as Betamethasone or Mometasone over the lesions once or twice a day
  • Avoid scratching to prevent damage to skin and subsequent infection
  • Use an OTC antihistamine to prevent itching

Ex: Cetirizine, Fexofenadine, Chlorpheniramine or Loratadine

  • Identify and avoid the triggers which can cause flares like excessive sweating, strong soaps, and detergents, pollen, certain foods, smoking, dust, stress etc.
  • Psoriasis


Psoriasis also comes under chronic common skin rashes which can appear on and off in a person’s lifetime. Skin cells are formed at a faster rate than they are shed. These skin cells accumulate as thick scales or plaques on skin surface. The lesions are dry and itchy. The rash is red or purplish in color with silvery scales. Itching can be mild to severe. As the skin is very dry, there can be a burning or stinging sensation.

There is a genetic predisposition to psoriasis and also a disturbance in the immune system. Certain triggers like excessive stress, smoking, sunburn and various infections can cause exacerbations. Psoriasis can associate with arthritis (Inflamed, painful, swollen joints) commonly in fingers and knees. The nails, scalp, and eyes can get affected too.

There are severe forms like pustular psoriasis where tiny blisters appear which are filled with pus and Erythrodermic psoriasis where the whole body appears red and peeling (Exfoliative dermatitis) with itching and severe burning sensation. Both these conditions are severe but luckily not common.

Heat Rash is characterized by tiny, red or white raised dots or lumps on the skin which can be very itching and irritable. Although it is commonly seen in babies, it can affect children and adults too. It is also called “Prickly heat”, because of the warm and prickly feeling. Sweat glands in the skin produce sweat or perspiration which comes out to the skin surface through pores or sweat ducts. When these pores are blocked, sweat is trapped under the skin.

It is common during warm and humid weather conditions (summer months) and in people living in tropical countries. Heat rash will spontaneously recover with time, especially once the weather conditions are reversed.
