Your questions on psoriasis answered

How does psoriasis present itself?

Psoriasis is “characterised by the development of erythematous, indurated, scaly, sometimes pruritic, and often painful skin lesions,” explains Dr Armstrong. But, what does this mean? Well, essentially it translates to red, thickened, scaly, sometimes itchy, and often painful skin lesions. “These lesions, known as plaques, commonly appear on the elbows, knees, scalp, and lower back, but can affect any part of the body.”

What causes psoriasis?

While “the exact cause of psoriasis is not fully understood”, psoriasis is a product of rapid cell turnover. It can be a “combination of genetic and environmental factors, with the latter elements including (but not limited to) infections, stress, skin injuries, and certain medications”, notes Dr Armstrong.

Do steroid creams help psoriasis?

In short, yes. “They work by reducing the inflammatory response caused by the overactive immune system. Therefore, they reduce redness, swelling and discomfort of itching and irritation,” she notes, before adding that steroid creams work to reduce cell turnover and minimise scaling.

What does coal tar do for psoriasis?

It “reduces scaling, itching and inflammation,” says Dr Armstrong and, for those experiencing symptoms of psoriasis around their scalp, she recommends Neutrogena T Gel shampoo (£10.49, Lookfantastic.com) with coal tar extract. For coal tar body treatments, she’d recommend Exorex lotion (£16.99, Amazon.co.uk), which features a minimal and transparent ingredients list, including no less than five per cent coal tar solution.

Can you use soap with psoriasis?

“Traditional soaps can worsen psoriasis,” explains Dr Armstrong, because they “can contain harsh detergents, fragrances and preservatives that can strip the skin of its natural oily barrier, which is protective” and, therefore, cause dryness and irritation. Instead, she recommends soap substitutes such as a Cetraben wash (£7.99, Boots.com).
