Understanding Psoriasis: What It Is, What Causes It and How to Care for Your Skin

August 5, 2026

If you or someone you know lives with psoriasis, you'll understand that it's much more than just dry skin. Psoriasis is a long-term skin condition that can cause patches of red, inflamed skin covered with silvery scales. While symptoms vary from person to person, one thing remains the same – looking after your skin every day can make a real difference to comfort and confidence.

In this guide, we'll explain what psoriasis is, what can trigger flare-ups and how a gentle skincare routine can help keep your skin feeling its best.

What Is Psoriasis?

Psoriasis is a chronic autoimmune skin condition that causes skin cells to renew much faster than normal. Instead of taking around a month for new skin cells to develop, the process can happen in just a few days. This leads to a build-up of skin cells on the surface, creating raised, flaky patches known as plaques.

Psoriasis isn't contagious, so you can't catch it from another person or pass it on through touch.

Although there's currently no cure, many people successfully manage their symptoms through a combination of medical treatment, lifestyle choices and good skincare.

Common Symptoms

Psoriasis affects everyone differently, but common symptoms include:

Red patches of skin
White or silvery scales
Dry, cracked skin that may bleed
Itching or burning sensations
Thickened or ridged nails
Soreness around affected areas

Symptoms often come and go, with periods of improvement followed by flare-ups.

Where Does Psoriasis Usually Appear?

Psoriasis can develop anywhere on the body, but it's most commonly found on:

Elbows
Knees
Scalp
Lower back
Hands
Feet

Some people experience small patches, while others may have larger areas affected.

What Can Trigger a Flare-Up?

Although the exact cause isn't fully understood, certain triggers are known to make psoriasis worse.

These can include:

Stress
Cold, dry weather
Skin injuries such as cuts or sunburn
Certain medications
Infections such as sore throats
Smoking
Excessive alcohol consumption

Keeping track of your triggers can help you better manage future flare-ups.

Why Moisturising Matters

One of the simplest yet most effective ways to support psoriasis-prone skin is by keeping it well moisturised.

A good moisturiser can help:

Reduce dryness
Improve skin comfort
Minimise cracking
Soften rough, scaly patches
Support the skin's natural protective barrier

Applying moisturiser after bathing, while your skin is still slightly damp, helps lock in hydration.

Choosing the Right Skincare Products

When your skin is sensitive, choosing gentle skincare products becomes even more important.

Look for products that:

Are fragrance-free or lightly scented for sensitive skin
Help replenish moisture
Support the skin barrier
Contain nourishing ingredients suitable for dry skin
Avoid harsh exfoliants or strong alcohol-based formulas

At SEB Skincare, we believe skincare should work with your skin, not against it. Gentle, nourishing products can help maintain hydration and leave skin feeling softer and more comfortable as part of your everyday skincare routine.

Everyday Tips for Caring for Psoriasis-Prone Skin

Small daily habits can have a big impact.

Keep Showers Warm, Not Hot

Hot water may feel soothing, but it can strip away your skin's natural oils. Warm showers are usually a better choice.

Moisturise Every Day

Consistency is key. Even when your skin feels good, regular moisturising helps maintain the skin barrier.

Avoid Scratching

Scratching can damage the skin and may worsen irritation. Instead, try applying a moisturiser if your skin feels itchy.

Wear Soft Clothing

Natural, breathable fabrics such as cotton are often more comfortable than rough or tight-fitting materials.

Stay Hydrated

Drinking enough water supports your overall health and helps maintain healthy-looking skin.

Can Diet Help?

There's no single diet that cures psoriasis, but many people find that eating a balanced diet rich in fruit, vegetables, whole grains and healthy fats supports their overall wellbeing.

Some people also notice that reducing alcohol or maintaining a healthy weight helps reduce flare-ups, although everyone's experience is different.

If you're considering major dietary changes, it's always worth discussing them with your GP or healthcare professional.

When Should You See a Doctor?

If your psoriasis becomes painful, spreads rapidly, affects your daily life or you develop swollen, painful joints, it's important to seek medical advice.

A healthcare professional can recommend treatments tailored to your individual needs, which may include medicated creams, light therapy or prescription medicines.

Looking After Your Skin Every Day

Living with psoriasis can be challenging, but developing a gentle daily skincare routine can help improve comfort and support healthier-looking skin.

Simple habits like moisturising regularly, avoiding harsh products and understanding your personal triggers can all play a part in keeping your skin feeling its best.

At SEB Skincare, we're passionate about creating skincare that supports dry and sensitive skin with gentle, nourishing ingredients. While skincare isn't a cure for psoriasis, choosing products that help maintain your skin's natural barrier can become an important part of your everyday self-care routine.
