Around 125 million people worldwide live with psoriasis, a chronic skin condition that affects not only the body but also mental and emotional well-being. In the UK, the Global Psoriasis Atlas estimates that it affects 2–3% of the population. 6 in 10 sufferers say it disrupts their daily lives.

Public figures such as Beyoncé, Kim Kardashian, Aljaž Škorjanec, and Cyndi Lauper have spoken openly about their experiences, helping to challenge stigma and raise awareness.

Psoriasis occurs when the immune system mistakenly attacks healthy skin cells, triggering inflammation and rapid cell turnover. This leads to the formation of red, scaly plaques, often appearing on the scalp, elbows, or knees, but it can affect any area, including the nails. Beyond these visible signs, the condition has been linked to higher risks of cardiovascular disease, metabolic syndrome, stroke, and depression.

“Psoriasis is a common, life-ruining skin disease that is associated with other serious medical conditions such as heart disease, arthritis, and depression,” warns Professor Chris Griffiths, consultant dermatologist at The Devonshire Clinic and one of the world’s leading experts in psoriasis care. “We need to move beyond the misconception that psoriasis is merely cosmetic. With the advent of powerful, targeted therapies, early diagnosis and treatment, coupled with greater public understanding, are vital to helping patients live healthier, more confident lives.”

Triggers that worsen psoriasis

Professor Griffiths explains that several lifestyle and environmental factors can cause flare-ups or make symptoms worse:

• Stress. Emotional strain increases inflammation and can trigger outbreaks.
• Skin injuries. Cuts, scrapes, or sunburn may lead to new patches.
• Infections. Bacterial or viral infections can activate the immune response.
• Irritants. Harsh soaps and fragrances may aggravate the skin.
• Unhealthy diet. Low fibre intake and excess processed foods can contribute to inflammation.
• Weight gain. Being overweight can make psoriasis more resistant to treatment.
• Smoking and alcohol. Both can increase the frequency and severity of flare-ups.

Lorraine Blumsum, 60, from London, has lived with psoriasis for more than 15 years. “Psoriasis has taken over my life,” she says. “It’s on my elbows, knees, scalp, stomach, and under my nails. There’s no escaping it. I’ve tried every cream, ointment, and medication, but nothing seems to make it go away.”

She adds, “Many think it’s just dry skin, but it’s incredibly painful, depressing, and embarrassing. I avoid wearing short sleeves, I had to ask for a different work uniform to hide my skin, and I dread social events. My daughter’s wedding is in Greece next year, and instead of being excited, I’m terrified about wearing a swimsuit. Psoriasis makes you feel trapped in your own skin.”

Treatment and lifestyle management

Professor Griffiths, who holds the Foundation for Skin Research Chair of Dermatology at the University of Manchester and leads the UK’s largest psoriasis clinic, says timely intervention can transform lives. Recent advances in biologic therapies, such as IL-17 and IL-23 inhibitors, have achieved clearance rates exceeding 90% in clinical trials, according to the British Association of Dermatologists and the National Institute for Health and Care Excellence (NICE).

He also highlights the importance of managing lifestyle factors alongside medical treatment:

• Exercise regularly. Physical activity improves circulation and reduces stress hormones.
• Eat an anti-inflammatory diet. Increase intake of fruits, vegetables, seeds, nuts, and oily fish while cutting down on red meat.
• Prioritise sleep. Adequate rest supports immune balance and skin recovery.
• Avoid smoking and excess alcohol. Both can worsen symptoms and slow treatment progress.
• Practise mindfulness. Meditation and deep breathing help manage emotional triggers.
• Spend time outdoors. Natural light can boost both skin and mood health.

Early diagnosis remains key, as untreated psoriasis can lead to psoriatic arthritis in up to 30% of cases, according to NHS guidance. “These strategies, combined with modern treatments, empower patients to take back control,” says Professor Griffiths.

For people like Lorraine, ongoing research offers hope. As scientific understanding of psoriasis and its psychological effects continues to grow, experts believe the outlook for patients’ quality of life will keep improving.
