Psoriasis is a chronic inflammatory skin condition that causes red, scaly patches on the skin. It most commonly affects the scalp, elbows, knees and lower back, but it can involve any area, including the nails and, in some patients, the joints (psoriatic arthritis).
The condition tends to fluctuate over time, with periods of flare and improvement. It is not contagious. While there is no permanent cure, modern treatments can control symptoms very effectively and, in many cases, achieve clear or almost clear skin.
At Atlas Dermatology, treatment is tailored to the severity of the condition, the areas involved, associated symptoms and your overall health.
Treatment options Topical treatments
For mild to moderate psoriasis, creams and ointments are often the first step. These may include:
- Corticosteroids to reduce inflammation
- Vitamin D analogues to slow skin cell turnover
- Combination treatments for improved effectiveness
- Tar-based or keratolytic preparations in selected cases
These treatments are effective when used correctly and consistently, and are often part of long-term maintenance.
Phototherapy
Medical phototherapy uses controlled ultraviolet light to reduce inflammation and slow excessive skin cell growth.
- Narrowband UVB is the most commonly used form
- Treatments are usually performed several times per week
- It is particularly useful for more widespread psoriasis
Phototherapy is a well-established and effective option when topical treatments alone are insufficient.
Systemic treatments
For more extensive or resistant psoriasis, tablets or injectable treatments may be required. These include:
- Methotrexate
- Ciclosporin
- Acitretin
- Apremilast
These medications work by reducing inflammation and controlling the overactive immune response driving psoriasis. They require monitoring and careful selection.
Biologic therapies
Biologic treatments are highly targeted therapies that block specific pathways in the immune system responsible for psoriasis.
Commonly used biologics include:
- Anti – TNF-alpha such as Adalimumab and Infliximab
- Anti – IL-17 such as Ixekizumab, Bimekizumab, Risankizumab
- Anti – IL-23 such as Guselkumab, Tindrakizumab
These treatments are very effective and can lead to significant or complete clearing of the skin in many patients. They are usually considered in moderate to severe psoriasis or when other treatments have not been effective or suitable.
General care
- Regular use of moisturisers to reduce dryness and scaling
- Avoiding known triggers such as skin injury, stress, infections and excessive alcohol
- Managing associated conditions such as obesity or metabolic syndrome
Frequently Asked Questions
Is psoriasis contagious?
No. Psoriasis cannot be passed from person to person.
Can psoriasis be cured?
Psoriasis is a long-term condition, but it can usually be controlled very well with appropriate treatment. Many patients achieve long periods of clear or almost clear skin.
Will I need treatment forever?
Treatment is often needed long-term, but it can be adjusted depending on how active the condition is. Some patients require only intermittent therapy, while others benefit from ongoing maintenance treatment.
What is psoriatic arthritis?
Some patients with psoriasis develop joint inflammation, known as psoriatic arthritis. Symptoms include joint pain, stiffness and swelling. Early diagnosis is important, as effective treatments are available.
Are biologics safe?
Biologic therapies are generally very well tolerated and have been extensively studied. They do, however, require careful screening and ongoing monitoring, which is part of specialist care.
When should I see a dermatologist?
You should seek specialist care if psoriasis is widespread, affecting your quality of life, involving sensitive areas such as the face or genitals, associated with joint symptoms, or not responding to standard treatments. A personalised treatment plan can make a significant difference.
