Psoriasis: Causes, Symptoms, Treatment

Psoriasis is an enduring autoimmune skin ailment marked by the accelerated accumulation of skin cells, resulting in the development of thick, red, and scaly patches. This condition is non-contagious, and while its precise cause remains incompletely comprehended, it is thought to arise from a blend of genetic and environmental influences.


  • Genetics: A family history of psoriasis increases the risk of developing the condition.
  • Immune system dysfunction: Psoriasis is considered an autoimmune disease where the immune system mistakenly attacks healthy skin cells, leading to the rapid growth of skin cells.
  • Environmental factors: Triggers such as stress, infections, and certain medications can exacerbate or trigger psoriasis in susceptible individuals.


  • Red patches of skin: Often covered with silvery scales.
  • Dry, cracked skin: Itching and burning sensations may accompany the dryness.
  • Thickened or pitted nails: Psoriasis can affect the nails, causing changes in color and texture.
  • Joint pain: In some cases, a type of arthritis called psoriatic arthritis may develop, causing joint pain and swelling.

Types of Psoriasis:

  • Plaque Psoriasis: The most common form, characterized by raised, red patches covered with a silvery white buildup of dead skin cells.
  • Guttate Psoriasis: Small, dot-like lesions that often develop after a streptococcal throat infection.
  • Inverse Psoriasis: Smooth, red patches in skin folds, such as the armpits, groin, and under the breasts.
  • Pustular Psoriasis: White, pus-filled blisters surrounded by red skin.
  • Erythrodermic Psoriasis: Widespread redness, severe itching, and skin shedding over large areas of the body.


1. Topical Treatments:

  • Corticosteroids: Reduce inflammation and itching. You can consult a dermatologist like Sana Younas for further information.
  • Topical Retinoids: Derived from vitamin A, they help slow skin cell growth.
  • Calcineurin Inhibitors: Suppress the immune system and reduce inflammation.

2. Phototherapy (Light Therapy):

  • UVB Phototherapy: Exposure to UVB light to slow the growth of skin cells.
  • Psoralen plus UVA (PUVA): Combining a light-sensitizing medication with UVA exposure.

3. Systemic Medications:

  • Oral Retinoids: Synthetic forms of vitamin A to slow skin cell growth.
  • Methotrexate: Suppresses the immune system.
  • Biologics: Target specific parts of the immune system involved in psoriasis.

4. Lifestyle and Home Remedies:

  • Moisturizers: To alleviate dryness.
  • Avoiding Triggers: Identifying and avoiding factors that worsen symptoms.
  • Stress Management: Stress reduction techniques may help manage outbreaks.

It’s crucial to consult with a dermatologist for a proper diagnosis and personalized treatment plan based on the severity and type of psoriasis. The effectiveness of treatments can vary from person to person.
