What is Psoriasis?

Psoriasis is a chronic autoimmune skin disorder characterized by the rapid buildup of skin cells. It causes the skin cells to multiply and accumulate at an accelerated rate, resulting in thick, red patches covered with silver-white scales. These patches, known as plaques, commonly appear on the elbows, knees, scalp, lower back, and other areas of the body.

Treating Psoriasis

Treating psoriasis involves a multifaceted approach aimed at managing symptoms, reducing inflammation, and slowing down excessive skin cell growth. Here are some common treatment options:

Topical Treatments: 

These medications are applied directly to the affected skin and are often the first line of treatment for mild to moderate psoriasis. They include corticosteroids, vitamin D analogues, retinoids, salicylic acid, and coal tar preparations


Phototherapy involves exposing the skin to ultraviolet (UV) light under medical supervision. UVB phototherapy and PUVA (psoralen plus ultraviolet A) are two common types of light therapy used for psoriasis treatment. 

Systemic Medications: 

For moderate to severe cases of psoriasis that do not respond to other treatments, systemic medications may be prescribed. These medications work throughout the body and can include oral retinoids, methotrexate, cyclosporine, and oral immunomodulators. 

What are the Types of Psoriasis?

There are several types of psoriasis, each with its own distinct characteristics. Here are the main types of psoriasis:

Plaque Psoriasis: 

This is the most common type, characterized by raised, red patches covered with silvery scales. These patches often appear on the elbows, knees, scalp, and lower back.

Guttate Psoriasis: 

Guttate psoriasis typically begins in childhood or early adulthood and is characterized by small, dot-like lesions on the skin. It is often triggered by a bacterial or viral infection, such as strep throat.

Inverse Psoriasis: 

Inverse psoriasis appears as smooth, red lesions in the folds of the skin, such as the armpits, groin, and under the breasts. It is more common in people who are overweight or have deep skin folds.

Pustular Psoriasis: 

Pustular psoriasis is characterized by raised, pus-filled blisters surrounded by red skin. It can be localized to certain areas of the body or generalized, affecting larger areas or even the whole body.

Erythrodermic Psoriasis: 

This is a rare but severe form of psoriasis that affects the entire body. It causes intense redness, shedding of scales, and can be accompanied by severe itching and pain.

Scalp Psoriasis: 

Scalp psoriasis affects the scalp, leading to red, itchy patches covered with thick scales. It can also extend to the forehead, back of the neck, and behind the ears.

Symptoms of Psoriasis

The symptoms of psoriasis can vary depending on the type and severity of the condition. Here are some common symptoms of psoriasis:

  • Red, raised patches of skin with silvery scales (plaque psoriasis).
  • Small, dot-like lesions on the skin (guttate psoriasis).
  • Smooth, red lesions in skin folds (inverse psoriasis).
  • Pus-filled blisters surrounded by red skin (pustular psoriasis).
  • Intense redness and shedding of scales affect the entire body (erythrodermic psoriasis).
  • Red, itchy patches on the scalp with thick scales (scalp psoriasis).
  • Dry, cracked skin that may bleed or be painful.
  • Itching, burning, or soreness in the affected areas.
  • Nail changes, such as pitting, discolouration, or separation from the nail bed.
  • Joint pain, stiffness, or swelling (psoriatic arthritis, a related condition).

Causes of Psoriasis

The exact cause of psoriasis is not fully understood, but it is believed to be a result of various factors. Here are some key points on the causes of psoriasis:

Genetic Predisposition: 

Psoriasis tends to run in families, indicating a genetic component. Certain genes associated with the immune system and skin cell regulation may contribute to the development of psoriasis.

Immune System Dysfunction: 

Psoriasis is considered an autoimmune disease, where the immune system mistakenly attacks healthy skin cells. This immune system dysfunction leads to the rapid growth of skin cells and the inflammation seen in psoriasis.

Environmental Triggers: 

Various environmental factors can trigger or exacerbate psoriasis symptoms. These triggers can include tension, infections (such as strep throat or skin infections), injuries to the skin, certain medications (such as beta-blockers or lithium), and smoking.

Koebner Phenomenon: 

Some people with psoriasis experience the Koebner phenomenon, where new psoriasis lesions develop at the site of skin injury or trauma, such as cuts, scrapes, or sunburn.

Lifestyle Factors: 

Certain lifestyle choices, such as obesity, smoking, excessive alcohol consumption, and poor diet, may contribute to the development or worsening of psoriasis.

How do you Stop Psoriasis from Spreading?

To stop psoriasis from spreading, it is essential to establish a consistent skincare routine, avoid triggers that worsen symptoms, protect the skin from injury, manage tension levels, and maintain a healthy lifestyle. By following these measures, individuals can minimize the risk of psoriasis flare-ups, reduce inflammation, and prevent the spread of the condition to unaffected areas of the skin.

Best Natural Ingredients For Psoriasis

Aloe Vera: 

Known for its soothing properties, aloe vera can help reduce redness, inflammation, and itching associated with psoriasis. Apply pure aloe vera gel directly to the affected areas or look for skincare products containing aloe vera.


Curcumin, the active compound in turmeric, has anti-inflammatory and antioxidant properties that may help alleviate psoriasis symptoms. It can be taken orally as a supplement or applied topically as a paste with turmeric powder and water.

Tea Tree Oil: 

Tea tree oil has antimicrobial and anti-inflammatory properties, which can help relieve itching and inflammation associated with psoriasis. Dilute tea tree oil with carrier oil (such as coconut or olive oil) and apply it to the affected skin.

Dead Sea Salts: 

Bathing in water with Dead Sea salts can help soothe and soften psoriasis plaques. The high mineral content in Dead Sea salts is believed to have beneficial effects on the skin.

Take Away

Psoriasis is a chronic skin condition causing red, scaly patches. It is influenced by genetics and immune system factors. Although there is no cure, treatments like topical medications and phototherapy can help manage symptoms and improve quality of life. Understanding the causes and available options empowers individuals to take control of their psoriasis and well-being.


Q: Where does psoriasis usually start?

A: Psoriasis typically starts on the elbows, knees, scalp, lower back, and nails, but it can occur anywhere on the body.

Q: Is Vaseline good for psoriasis?

A: Vaseline can provide temporary relief for psoriasis by moisturizing and soothing dry, itchy skin. It helps create a barrier to prevent moisture loss and can be particularly beneficial for areas with thick scales. 

Q: What vitamins are good for psoriasis?

A: Certain vitamins have shown potential benefits for psoriasis. Vitamin D, whether obtained through sunlight exposure or supplements, can help regulate the immune system and reduce inflammation. Omega-3 fatty acids, found in fish oil or flaxseed oil, may also have anti-inflammatory effects.
