In the skin

Immune signals speed up the production of skin cells. The cells accumulate in thickened, inflamed plaques with surface scale.

Immune inflammation accelerates skin-cell production and shedding. Small, scattered scaly patches develop; the rash itself is not contagious.

Daily care

Habits that help

Moisturize regularly with a plain fragrance-free product
Apply after washing and when skin feels dry or tight.
Keep washing gentle and water lukewarm
Use a non-soap cleanser and pat dry rather than rubbing.
Protect sore skin from friction and minor injury
Comfortable clothing and gentle handling reduce avoidable irritation.
Keep a manageable record of flares and symptoms
Note new medicines, infections or joint symptoms to discuss at review.
Follow the plaque psoriasis care plan
Use bland moisturizer, avoid rubbing and follow a site-appropriate treatment plan.
Discuss phototherapy or systemic-treatment assessment
More extensive or disabling psoriasis may need supervised light treatment or prescription systemic therapy.

Avoid

Avoid: Picking scale or scratching plaques
Injury can worsen psoriasis and create breaks in the skin.
Avoid: Unsupervised tanning or harsh home exfoliation
Sunburn and irritation can trigger worsening; prescribed phototherapy is different from tanning.

Report a recent sore throat or signs of infection
Assessment may be needed; skin moisturization does not treat an active throat infection.
Follow the guttate psoriasis care plan
Use bland moisturizer, avoid rubbing and follow a site-appropriate treatment plan.

Treatment differences

Evidence labels come from each condition’s own treatment list.

Treatment

Prescription topicals

Topical corticosteroid and vitamin D treatment

Common options for localised plaques; selection depends on site and thickness.

Outlook

Long term

Plaque psoriasis often alternates between flares and quieter periods. Treatment can achieve good control, but maintenance is commonly needed and the tendency to psoriasis remains.

Many episodes clear within about 3–4 months. It can recur, and some people later develop persistent plaque psoriasis; follow-up is useful if spots do not settle.

Complications

Possible complications

Psoriasis can accompany inflammatory joint disease. Report persistent joint stiffness or swelling.

When to get help

Seek care for painful cracks, widespread flares, joint symptoms or uncertain diagnosis.

Arrange assessment for a first widespread eruption or a recent sore throat; antibiotics treat confirmed infection rather than reliably clearing the rash.
