Is Psoriasis Hereditary ? Understanding the Genetic Link and How to Manage It

Psoriasis is one of those conditions that often runs in families — but not everyone who has a parent or sibling with psoriasis will develop it themselves. This raises an important question many Australians ask: is psoriasis hereditary?

Let’s explore what science says about the genetic and environmental causes of psoriasis, how it’s passed down through families, and — most importantly — how to manage it effectively using natural, dermatologist-trusted products from Australian Psoriasis and Eczema Supplies.


What Is Psoriasis?

Psoriasis is a chronic autoimmune condition that causes the rapid buildup of skin cells, leading to dry, scaly, and inflamed patches on the skin. These patches — often referred to as “plaques” — can appear on the scalp, elbows, knees, back, or even under the nails.

It’s not contagious, but it’s often genetically influenced and can flare up due to triggers like stress, weather changes, skin injury, and certain medications.


Is Psoriasis Hereditary? The Genetic Evidence

The short answer is yes — psoriasis has a strong hereditary component.

Researchers estimate that up to 40% of people with psoriasis have a close family member who also has the condition. However, the presence of psoriasis genes doesn’t guarantee that you’ll develop symptoms — it simply increases your risk.

The Role of Genes

Scientists have identified more than 25 genetic regions linked to psoriasis, known as PSORS (Psoriasis Susceptibility) genes. The most notable is PSORS1, located on chromosome 6, which plays a key role in immune system regulation and skin cell growth.

If one parent has psoriasis, a child has about a 10% chance of developing it. If both parents have psoriasis, the risk can rise to 50% or more.

That said, genetics are only part of the story. Many people with psoriasis-related genes never develop symptoms at all — meaning something else must “switch on” the condition.


Triggers That Activate Psoriasis

Even with a hereditary predisposition, psoriasis often requires environmental or immune triggers to appear. Common triggers include:

1. Stress and Anxiety

Emotional stress is one of the most common triggers for flare-ups. High stress levels increase inflammatory responses in the body, which can worsen psoriasis symptoms.

💡 Tip: Incorporating daily relaxation techniques like meditation or light exercise can help keep stress hormones under control.

2. Infections and Illness

Throat infections, skin infections, or viral illnesses can trigger psoriasis, especially in people with the genetic markers for it.

3. Skin Injury (Koebner Phenomenon)

Cuts, burns, or even sunburn can cause new psoriasis patches to develop on previously unaffected skin.

4. Cold Weather

Dry air and reduced sunlight during winter can lead to itchy, flaky skin. This is why many Australians notice their psoriasis worsening in cooler months.

5. Medications

Certain drugs — including beta-blockers, lithium, and some anti-inflammatories — can cause or worsen psoriasis.


Is Psoriasis Hereditary ? Can You Prevent Psoriasis if It’s in Your Family?

While you can’t change your genetic makeup, you can influence how your genes express themselves. This concept, known as epigenetics, means that lifestyle and environmental factors play a huge role in determining whether psoriasis develops or remains dormant.

Here’s what you can do to reduce your risk and manage flare-ups effectively:

Stay Hydrated and Moisturised

Keeping your skin barrier healthy is crucial. Regularly applying deeply hydrating creams helps lock in moisture and reduce inflammation.

At Australian Psoriasis and Eczema Supplies, some of the most effective options include:

  • Soothing Skin Relief Cream – a rich, natural formula designed to calm irritation, reduce redness, and support the skin’s natural healing process.

  • Sea Salt Shampoo – perfect for those experiencing scalp psoriasis. The mineral-rich salts help cleanse buildup while restoring balance to the scalp.

  • UVB Light Therapy Lamps – clinically proven to reduce psoriasis lesions by slowing abnormal skin cell growth using narrowband UVB light.

Avoid Harsh Soaps and Detergents

Choose gentle, non-fragranced cleansers that won’t strip your skin’s natural oils.

Manage Stress Levels

Chronic stress can trigger the immune response that leads to psoriasis. Incorporating breathing exercises, yoga, or regular walks can help regulate cortisol levels.

Get Moderate Sunlight

Natural sunlight provides UVB rays, which can help clear psoriasis patches in small doses. Just be careful to avoid burning — too much exposure can worsen symptoms.

Maintain a Balanced Diet

Omega-3 fatty acids, antioxidants, and vitamin D support healthy skin and reduce inflammation. Avoid excessive alcohol and highly processed foods, which can exacerbate flare-ups.


Understanding Genetic vs. Environmental Psoriasis

It’s important to note that hereditary psoriasis differs from triggered psoriasis.

Type Description Typical Triggers
Genetic Psoriasis Runs in families; may appear early in life; associated with immune system genes. Activated by stress, infections, cold weather, or skin trauma.
Environmental Psoriasis Occurs without a family history; often linked to lifestyle or environmental causes. Diet, alcohol, smoking, and medication use.

Both types respond to the same general treatments — but understanding your genetic background helps you anticipate and manage potential triggers early.


The Role of the Immune System

Psoriasis is primarily an autoimmune condition, meaning the body’s immune system mistakenly attacks healthy skin cells. This causes overproduction and inflammation, leading to the red, scaly patches typical of psoriasis.

If you’re genetically predisposed, your immune system may overreact to certain triggers — which is why targeting both skin and immune balance is key.

How Natural Skincare Can Help

Using products that calm inflammation and support skin regeneration is essential.

Australian Psoriasis and Eczema Supplies offers a curated selection of creams and treatments specifically chosen for sensitive, psoriasis-prone skin. Many of these products:

  • Contain natural botanical extracts to soothe irritation.

  • Are free from harsh chemicals and artificial fragrances.

  • Are Australian-made and dermatologist-tested for long-term use.


Is Psoriasis Hereditary and What If Psoriasis Runs in Your Family?

If your parents or siblings have psoriasis, you’re not destined to develop it — but you should take proactive care of your skin and lifestyle.

Here’s a practical routine to follow:

Morning Routine

  1. Cleanse gently with a mild, fragrance-free wash.

  2. Moisturise immediately after showering using a cream like Soothing Skin Relief Cream to seal in hydration.

  3. Protect your scalp with Sea Salt Shampoo or other scalp-care treatments.

Evening Routine

  1. Use lukewarm showers — avoid hot water, which can strip oils.

  2. Apply a rich emollient before bed to calm and hydrate.

  3. Consider UVB Light Therapy a few times per week, as recommended by your healthcare provider.


Can You Inherit Psoriasis Severity?

Interestingly, genetics don’t just affect whether you develop psoriasis — they may also influence how severe it becomes.

Certain gene variations (like HLA-Cw6) are linked to early onset and more aggressive flare-ups. However, lifestyle management plays a major role in determining how frequent and intense those flares are.

With consistent care and early intervention, people with hereditary psoriasis can experience long, symptom-free periods.


Emotional Impact: Breaking the Family Cycle

Watching multiple generations struggle with psoriasis can be emotionally draining. Many Australians find it affects confidence, relationships, and mental health.

That’s why holistic care — addressing both the physical and emotional aspects — is crucial.

💬 Remember: Psoriasis isn’t your fault. It’s not caused by poor hygiene, diet, or laziness — it’s a complex interplay of genetics and immunity.

Taking charge with the right treatments and mindset can help you break that generational pattern of frustration and discomfort.


When to Seek Professional Help

If your psoriasis is spreading, painful, or affecting your daily life, consult a dermatologist. They can confirm whether your condition is genetically influenced and suggest medical or light-based treatments.

For ongoing management between visits, Australian Psoriasis and Eczema Supplies offers a full range of supportive products designed to:

  • Reduce itching and redness

  • Restore moisture and comfort

  • Improve the appearance of plaques

  • Support skin’s natural healing barrier


Key Takeaway:  Is Psoriasis Hereditary?

So, is psoriasis hereditary?
Yes — but having the genes doesn’t mean you’re destined to develop it. Genetics may set the stage, but your environment, lifestyle, and skincare choices determine whether psoriasis actually appears or flares up.

By combining smart lifestyle management with gentle, effective products like those from Australian Psoriasis and Eczema Supplies, you can manage psoriasis symptoms and take back control of your skin health — regardless of family history.
