psoriasis aftercare at home

Overview

Psoriasis is a long-lasting skin condition where the body makes skin cells too quickly, causing raised, scaly patches. It is not contagious, and it is not caused by poor hygiene.

Yes, psoriasis is a common condition. According to the UK's National Health Service, about 1 in 50 people have it.

It can appear at any age, but it most often starts in people between 15 and 30 years old. Both men and women can get it.

Symptoms

Common symptoms

• Thick, red, scaly patches of skin (called plaques) usually on elbows, knees, scalp, lower back, or nails
• Patches that itch, burn, or feel sore
• Dry skin that may crack
• Nails that become thick, pitted, or ridged
• Dandruff-like scaling on the scalp

Symptoms in children

• In children, patches may be smaller and more numerous
• Scalp psoriasis is common
• Small, teardrop-shaped spots can appear suddenly, often after a sore throat – this is sometimes called guttate psoriasis

Symptoms in older adults

• In older adults, skin may look less red and scaling may be lighter
• Patches can be drier and itchier
• Joint pain and swelling (arthritis related to psoriasis) are more likely

Causes

Main causes

• Psoriasis happens when the immune system (the body's defense system) mistakenly attacks healthy skin cells. This makes skin cells grow too fast and pile up into patches.
• Genetics play a part, meaning it can run in families.
• Certain triggers can cause a flare-up in someone who already has psoriasis.

Risk factors

• Family history of psoriasis
• Stress
• Skin injuries such as cuts, scrapes, or severe sunburn
• Infections, especially strep throat
• Cold, dry weather
• Heavy alcohol use and smoking
• Some medicines (such as those for malaria, high blood pressure, or mood disorders) – talk to your doctor about your medicines

When to see a doctor

See a doctor urgently if:

• If you have a painful flare that makes it hard to sleep or do daily tasks
• If you have signs of infected skin
• If you develop sudden joint pain and swelling
• If a large area of your body becomes red and tender

Book a routine appointment if:

• If you notice patches that do not go away
• If your symptoms bother you or get in the way of daily life
• If over-the-counter moisturizers are not helping
• If your scalp or nails are affected
• If you want help finding a treatment plan that works for you

Diagnosis

A doctor or skin specialist will usually recognize psoriasis by looking at your skin, scalp, and nails. They will ask about your family history, symptoms, and any triggers you have noticed.

Tests that may be done

• A skin biopsy – a small sample of skin taken and checked under a microscope – is sometimes done to rule out other conditions
• In some cases, blood tests or an X-ray may be needed if joint symptoms are present

What to expect at your appointment

When you see a doctor, they will ask you to describe your symptoms and show areas that bother you. They may use a lamp or magnifying glass to look closely. The visit usually takes 15–30 minutes, and you can ask questions.

Treatment

There is no cure for psoriasis yet, but treatments can help clear patches, reduce itching, and prevent flare-ups. Your treatment plan will depend on how severe your psoriasis is, where it appears, and how it affects your life.

Self-care at home

• Moisturize daily with a thick, fragrance-free moisturizer, especially after bathing
• Take short, warm baths or showers (not hot) with gentle cleansers
• Pat your skin dry – do not rub
• Avoid scratching; use a cold compress or anti-itch lotion (ask your pharmacist for options)
• Get a little sunlight on your skin, but avoid sunburn
• Wear loose, soft clothing to avoid irritating patches
• Manage stress with relaxation, breathing exercises, or talking with someone you trust

Medical treatments

Doctors use a range of treatments. Mild psoriasis may be treated with creams, ointments, and shampoos you put on your skin. For moderate or severe psoriasis, light therapy (careful use of ultraviolet light) or medicines that work throughout the body may be offered. Your doctor will explain the options, including how to use them and possible side effects. You should never start or stop a treatment without speaking to your doctor.

Living with this condition

Living with psoriasis means caring for your skin daily and watching for triggers that cause flare-ups. It can take time to find a routine that works for you. Keep your skin moisturized, protect it from cuts and sunburn, and continue your treatment even when your skin looks clear.

Lifestyle tips

• Find ways to lower stress, such as meditation, yoga, hobbies, or talking to a friend
• If you smoke, consider quitting – smoking can make psoriasis worse
• Limit alcohol, as it can trigger flare-ups in some people
• Stick to a gentle skin care routine
• Get enough sleep to support your overall health

Diet and exercise

There is no 'psoriasis diet' that works for everyone, but eating a balanced diet with plenty of fruits, vegetables, whole grains, and healthy fats can help your overall health. Regular exercise helps control weight and relieve stress, which may reduce flare-ups. If joints are painful, choose low-impact activities like walking, swimming, or cycling.

Mental health and emotional wellbeing

Psoriasis can affect how you feel about yourself, especially if it is on visible parts of your body. It may cause worry, frustration, or low mood. These feelings are normal. It can help to talk openly with your doctor, friends, or family. If you feel overwhelmed, consider asking for a referral to a counselor or therapist who understands chronic conditions.

Prevention

Psoriasis cannot be prevented, but you can often avoid or reduce flare-ups by learning what triggers your symptoms. Common triggers include stress, skin injury, infections, cold weather, smoking, and heavy drinking.

Vaccines

Stay up to date with recommended vaccinations, such as the annual flu shot. Talk to your doctor about which vaccines are right for you, especially if you are taking medicines that affect your immune system.

Screening programmes

People with psoriasis may have a higher risk of heart disease and diabetes. Your doctor may suggest regular checks of your blood pressure, cholesterol, and blood sugar to keep your heart healthy.

Complications

If left untreated

• Psoriatic arthritis – joint pain, stiffness, and swelling – may develop even if skin symptoms are mild
• Skin infections from cracked or scratched skin
• Emotional stress, low self-confidence, and depression
• Increased risk of heart disease and high blood pressure in some people

Long-term outlook

Psoriasis is a long-term condition, but most people live full and active lives. With modern treatments and good self-care, many people achieve clear or nearly clear skin. It may take time to find the right plan, but there is good hope for controlling symptoms and feeling better.
