Psoriasis Treatment

What Is Psoriasis?

Psoriasis is a common, long-term (chronic) inflammatory skin condition that causes the immune system to speed up skin cell turnover. This results in the build-up of thick, scaly patches of skin, often accompanied by redness, itching, or soreness. Psoriasis can appear at any age, although it commonly starts in young adults or middle age.

It is not contagious, but it can run in families. Many people with psoriasis also experience periods of improvement followed by flare-ups, often triggered by factors such as stress, illness, or changes in the weather.

​

Types of Psoriasis

There are several different types of psoriasis, each with its own appearance and affected areas:

​

Plaque Psoriasis (Psoriasis Vulgaris)

This is the most common form. It causes raised, red patches covered in silvery-white scales, typically appearing on the elbows, knees, scalp, and lower back.

​

Scalp Psoriasis

Psoriasis on the scalp can be mistaken for dandruff. It may cause flaking, thick crusts, and itchiness, sometimes extending beyond the hairline to the forehead, neck, or ears.

​

Guttate Psoriasis

Often triggered by infections like strep throat, guttate psoriasis presents as small, drop-like red spots, mainly on the torso and limbs. It is more common in children and young adults.

​

Inverse Psoriasis

This type affects skin folds — such as the armpits, under the breasts, groin, or buttocks — and appears as smooth, shiny red patches that may be worsened by friction and sweating.

​

Pustular Psoriasis

Characterised by white pustules (blisters filled with non-infectious pus) surrounded by red skin, this form can be localised to the hands and feet or, more rarely, widespread across the body.

​

Nail Psoriasis

Psoriasis can also affect the fingernails and toenails, causing pitting, discolouration, thickening, and even nail separation.

​

Psoriatic Arthritis

Around 30% of people with psoriasis may develop psoriatic arthritis — a condition that causes joint pain, stiffness, and swelling. Early diagnosis is key to preventing joint damage.

​

Common Psoriasis Symptoms

Psoriasis can vary significantly in severity and appearance, but common signs and symptoms include:

• Red, raised patches of skin with white or silvery scales

• Itching, burning, or soreness in affected areas

• Dry, cracked skin that may bleed

• Thickened or ridged nails

• Flare-ups triggered by stress, illness, or environmental factors

• Joint pain or stiffness (in psoriatic arthritis)

​

What Causes Psoriasis?

The exact cause of psoriasis is complex and not fully understood. It involves an overactive immune response that speeds up the life cycle of skin cells. Instead of taking weeks for new skin cells to develop and rise to the surface, this process happens in just days — leading to a build-up of cells on the skin's surface.

​

Psoriasis Triggers

• Stress: Emotional or physical stress is a major trigger for many people.

• Infections: Especially strep throat or skin infections.

• Injury to the skin: Cuts, sunburn, insect bites, or even tattoos (Koebner phenomenon).

• Cold, dry weather: Can worsen symptoms.

• Smoking and alcohol: Linked to increased psoriasis severity.

• Certain medications: Some medicines can aggravate psoriasis (your dermatologist will discuss these with you).

• Hormonal changes: Psoriasis may worsen during puberty, pregnancy, or menopause.

​

How Is Psoriasis Diagnosed?

A dermatologist can usually diagnose psoriasis based on a visual examination and a detailed discussion of your symptoms and health history. In rare cases, a skin biopsy may be needed to rule out other skin conditions such as eczema, fungal infections, or dermatitis.

​

At Domain Dermatology, your psoriasis assessment may include:

• A thorough medical and family history

• Review of your skin, scalp, nails, and joints

• Discussion about triggers and previous treatments

• Advice on lifestyle changes that may help manage symptoms

• A tailored treatment plan based on your goals

​

Psoriasis Treatment Options

There is currently no cure for psoriasis, but with the right treatment plan, most people can achieve long-term control and clear or nearly clear skin.

We offer a range of treatments depending on the type and extent of your psoriasis, your general health, and your preferences.

​

1. Topical Treatments

These are applied directly to the skin and are typically the first step for mild to moderate psoriasis. They may include anti-inflammatory creams, vitamin-based agents, or treatments that slow down skin cell growth and reduce scaling and redness.

​

2. Phototherapy (Light Therapy)

UVB light therapy or narrowband phototherapy is a proven treatment for widespread or stubborn psoriasis. This involves controlled exposure to ultraviolet light, either in a clinic setting or via a prescribed home-based phototherapy unit.

​

3. Systemic Treatments

For moderate to severe psoriasis or psoriatic arthritis, systemic therapy may be recommended. These are prescription treatments taken orally or by injection that target the immune system. Your dermatologist will guide you through the risks and benefits of these therapies and provide careful monitoring.

​

4. Scalp and Nail-Specific Therapies

Specialised treatments for scalp psoriasis may include medicated shampoos, foams, and solutions. Nail psoriasis may require long-term treatment and monitoring, sometimes involving systemic therapy.

​

Psoriasis and Lifestyle: What You Can Do

• Moisturising regularly to prevent dryness and cracking
