Psoriasis: Myth-busting and must-known facts Post Date : July 31, 2025 Dermatology , Skincare 3 minutes read Psoriasis is a common skin condition that affects around 2–3% of the UK population, yet it remains widely misunderstood. Here, we set the record straight with key facts and important health advice for anyone living with psoriasis or supporting someone who is. Myth 1: “Psoriasis is just a skin condition” Fact: Psoriasis is more than skin deep. It’s a lifelong, immune-mediated condition that speeds up skin cell turnover. In people without psoriasis, skin cells are replaced roughly every 28 days. In psoriasis, this can happen in as little as 3–7 days. This accelerated skin production overwhelms the body’s ability to keep up with nutrient delivery and moisture balance, which leads to thick, dry, scaly patches on the skin, especially on the elbows, knees, scalp and lower back. Myth 2: “It’s not inherited” Fact: Psoriasis has a strong genetic component. If a close relative has psoriasis, your risk of developing it increases significantly. In fact, approximately 40 – 50% of people with psoriasis have a family history of the condition. Myth 3: “Psoriasis only affects the skin” Fact: Psoriasis can also affect the joints. Up to 30% of people with psoriasis develop a related condition called psoriatic arthritis. It can cause pain, stiffness, and swelling, often in the larger joints like knees, ankles, or fingers. If left untreated, it can lead to permanent joint damage and deformity. Early diagnosis and treatment are essential. If you have psoriasis and start to notice joint pain or swelling, speak to your healthcare provider as soon as possible. Myth 4: “Psoriasis is just a cosmetic issue” Fact: Psoriasis is linked to serious health risks, particularly cardiovascular disease. People with psoriasis are more likely to develop conditions like high blood pressure, high cholesterol, and heart disease. This means lifestyle choices really matter: – Don’t smoke – Maintain a healthy BM – Stay physically active – Eat a balanced diet – stress levels low, as stress can also trigger flare-ups Taking care of your overall health not only supports your heart and joints, it can also improve your skin and reduce flare-ups. Myth 5: “It can be cured with the right cream” Fact: Psoriasis is a lifelong condition, but the good news is there are many effective treatments, from topical therapies to phototherapy, tablets, and biologic injections. While there’s no cure, many people achieve excellent control and long periods of remission with the right treatment plan. In Summary Psoriasis is a complex condition that affects more than just the skin. It’s genetic, systemic, and potentially linked to joint and heart disease. But with the right support, lifestyle choices, and treatment, people with psoriasis can live full, healthy lives. If you have psoriasis and any concerns, particularly about joint pain or general health, speak to your GP or dermatologist. Early action makes a big difference.
