Why ask?

Psoriasis is not the same for everyone

Psoriasis is an inflammatory condition that acts throughout the body, although its most visible effects are on the skin1.

Right now, around 2% of the population has psoriasis2, and the majority (around 90%) has plaque psoriasis3, a form of the disease which causes red, raised plaques on the skin, which cause pain, itch and burning1.

Psoriasis can be a variable disease that presents in different ways1,4, so your experience with it will be personal.

When was the last time you spoke to someone about your psoriasis?

Advances in dermatology mean there are more options available for people with psoriasis than ever before.

And, as our understanding of the science behind psoriasis and how to manage it improves, physicians have started to expect more from the treatments they prescribe5.

Some people even find that if their psoriasis improves enough with treatment, their everyday life is no longer affected by the condition.6,7.

So isn’t it time to start taking back the things that you miss?

How will a dermatologist assess your skin?

As well as talking to you about your psoriasis and looking at your skin, there are a number of tools that your dermatologist can use to measure how severe your psoriasis is, and how it is affecting you.

PASI (Psoriasis Area and Severity Index)8,9

The PASI is considered the current ‘gold standard’ used to assess psoriasis. It measures the area of the body covered by psoriasis, as well as the redness, thickness and scaliness of the plaques. The PASI gives a score out of 72, but in reality scores above 30 are rare.

BSA (Body Surface Area)8,9

The BSA score is simply the percentage of your body covered by psoriasis – it is a much simpler and quicker measurement than the PASI, but can sometimes lead to the severity of psoriasis being overestimated.

DLQI (Dermatology Life Quality Index)10

The DLQI is a questionnaire that your dermatologist may use to assess the impact that psoriasis is having on your daily life – it’s made up of 10 questions, which cover day-to-day activities, clothing, leisure, work and school, personal relationships and treatment

Your dermatologist may use one of these tools, or several, depending on their personal preference, and your score will be just one of the factors they consider when making a treatment recommendation.
