Psoriasis is a long-term inflammatory skin condition that can cause patches of dry,
itchy, sore or flaky skin. The patches may look different depending on your skin
tone, and symptoms often fluctuate, with periods of improvement and flare-ups. Although
psoriasis cannot currently be cured, treatments can help control symptoms and improve
quality of life.

## What does psoriasis look like?

Psoriasis can cause raised, scaly patches that may appear on the scalp, elbows, 
knees, trunk, hands, feet or skin folds. On lighter skin, patches may look pink 
or red with pale scales; on darker skin, they may look darker, violet or grey and
can leave changes in skin colour after a flare. Nails may develop small dents, thickening
or discolouration.

## What causes psoriasis?

Psoriasis happens when the immune system affects the skin’s renewal process, causing
skin cells to build up too quickly. Genes can contribute, and it is not something
you can catch from another person. Possible flare triggers include stress, skin 
injury, some infections, smoking, alcohol and certain medicines. Triggers vary, 
so a simple symptom diary may help identify personal patterns.

## Treatment options

Treatment depends on the location and severity of symptoms. A clinician may recommend
moisturisers (emollients), vitamin D preparations, topical corticosteroids or scalp
treatments. More extensive psoriasis may need supervised light therapy or prescription
medicines that work throughout the body. Do not start, stop or share prescription
treatments without professional advice.

## Practical skin-care tips

 * Use fragrance-free moisturisers regularly and apply them gently.
 * Choose lukewarm rather than very hot showers and avoid harsh scrubbing.
 * Try to recognise personal triggers, manage stress and avoid smoking.
 * Follow instructions for prescribed creams, including where and how long to use
   them.

Emollients can make fabrics more flammable, so keep treated skin, clothing and bedding
away from cigarettes, naked flames and other ignition sources.

## When to seek medical advice

Speak to a GP or dermatologist if you think you have psoriasis, if treatment is 
not helping, or if you develop recurring joint pain, stiffness or swelling. Seek
urgent medical care if your skin rapidly becomes widespread and inflamed or develops
pus-filled bumps, especially with fever or feeling very unwell.

## Key takeaways

Psoriasis is not contagious, and a tailored treatment plan can make symptoms easier
to manage. Early assessment helps confirm the diagnosis and identify an appropriate
treatment approach.
