Psoriasis is an autoimmune condition characterised by the rapid build-up of skin cells resulting in a scaly skin surface. The condition may come and go throughout your lifetime. Skin psoriasis can develop due to either inherited or environmental factors. The outer layer of skin (the epidermis) contains skin cells that are continuously being replaced. This process normally takes between three to four weeks. However, with psoriasis, skin cells divide more quickly, and cells are both formed and shed in as little as three to four days.

Psoriasis is a long-term condition that comes and goes throughout your lifetime. Both genetic and environmental factors play a role in the development of psoriasis.



Psoriasis causes red and scaly skin. The skin changes due to psoriasis (known as plaques) are well defined, slightly raised pink or red areas with silvery-white scales. Psoriasis can also affect the nails, joints, neck, scalp and face, as well as the skin.

In most cases, people with psoriasis can go through cycles of symptoms. Psoriasis can cause severe symptoms for a few days or weeks, and then, the symptoms can clear up and be almost unnoticeable. Psoriasis can flare up again and can be made worse by a psoriasis trigger such as alcohol, injury, stress, certain medications and infection.

Psoriasis is now considered a systemic disease rather than just a skin condition. The disorder is associated with cardiovascular disease, arthritis, skin cancer formation and other diseases. For this reason, it is important to visit a dermatologist for early diagnosis and management of psoriasis with appropriate referrals.


Dermatologists are experts in treating psoriasis, and Dr Jacobs has also published an article in a medical journal on the subject. Treatment of psoriasis depends upon your individual needs. Topical treatment applied to the surface of your skin is sufficient for most patients. For people with more severe psoriasis, Dr Jacobs may recommend ultraviolet light treatment (phototherapy), tablet treatment or injection treatment.
