What Can Trigger Psoriasis?

Psoriasis can be uncomfortable and unpredictable. Some people experience long periods with mild symptoms, while others notice sudden flare-ups involving itching, scaling, inflammation, soreness, or new patches of affected skin.

Psoriasis is a chronic immune-mediated condition rather than a contagious skin infection. Although there is no single trigger that affects every patient, understanding common causes of flare-ups may help people recognize patterns and work with a qualified medical provider on a long-term management plan.

Diagnosis and treatment of active psoriasis should be managed by a dermatologist or another appropriate healthcare professional. Cosmetic skin procedures should not replace medical evaluation or prescribed treatment.

What is psoriasis?

Psoriasis develops when immune system activity causes skin cells to reproduce more rapidly than usual. These extra cells build up on the skin's surface and may form thickened, scaly, inflamed, or discolored patches.

Psoriasis commonly affects:

• The elbows
• The knees
• The scalp
• The lower back
• The hands and feet
• The nails
• Skin folds and other areas of the body

The appearance of psoriasis varies across different skin tones. Areas may look red, pink, purple, gray, brown, or darker than the surrounding skin. Scaling may appear white or silvery.

Is psoriasis contagious?

Psoriasis is not contagious. It cannot be spread through touching, hugging, sharing clothing, using the same towels, or having close contact with someone who has the condition.

Because some plaques may resemble infections, eczema, or other skin conditions, a professional diagnosis is important before beginning treatment.

What can trigger a psoriasis flare-up?

A flare-up occurs when existing psoriasis becomes more active or new areas appear. Triggers vary from person to person, and more than one factor may be involved.

Common psoriasis triggers may include:

• Skin injuries
• Infections
• Emotional or physical stress
• Certain medications
• Cold or dry weather
• Sunburn
• Smoking
• Excessive alcohol use
• Hormonal changes
• Harsh or irritating skin care products

Can skin injuries trigger psoriasis?

New psoriasis plaques may develop in areas where the skin has been injured or repeatedly irritated. This response is sometimes called the Koebner phenomenon.

Possible skin-related triggers include:

• Cuts and scrapes
• Burns
• Sunburn
• Insect bites
• Repeated scratching
• Friction from tight clothing
• Tattoos and piercings
• Aggressive cosmetic procedures

Protecting the skin, treating minor injuries carefully, and avoiding unnecessary irritation may help reduce this risk.

Can infections cause psoriasis symptoms to worsen?

Certain infections may activate the immune system and contribute to a flare. Strep throat is a well-known trigger for guttate psoriasis, particularly in children and younger adults.

Patients should contact a healthcare professional when a psoriasis flare occurs together with:

• Fever
• A persistent sore throat
• Unusual fatigue
• Signs of a skin infection
• Rapidly worsening symptoms

Treating an infection does not always make psoriasis disappear immediately, but appropriate medical care can reduce complications and support the overall treatment plan.

How does stress affect psoriasis?

Emotional and physical stress are frequently reported psoriasis triggers. Stress may influence inflammatory activity and can also make itching, discomfort, and sleep problems feel more intense.

Psoriasis itself may cause emotional strain, especially when symptoms are visible or interfere with work, sleep, exercise, or social activities.

Stress-management strategies may include:

• Maintaining a regular sleep routine
• Practicing breathing exercises
• Using meditation or mindfulness techniques
• Participating in suitable physical activity
• Seeking support from family or patient groups
• Speaking with a mental health professional when needed

Can medications trigger psoriasis?

Some medications may trigger psoriasis or worsen existing symptoms in certain patients. Examples may include selected beta-blockers, lithium, antimalarial medications, and other prescription drugs.

Suddenly stopping some systemic medications may also cause serious worsening.

Patients should never stop or change a prescription medication without speaking with the healthcare professional who prescribed it. A dermatologist and prescribing clinician can review whether a medication may be contributing to symptoms and discuss possible alternatives.

Can weather changes cause a flare?

Cold, dry weather may remove moisture from the skin and make itching, cracking, and scaling more noticeable. Indoor heating can further reduce humidity and increase dryness.

Helpful cold-weather habits may include:

• Applying a fragrance-free moisturizer regularly
• Using a humidifier indoors
• Taking brief showers with warm rather than hot water
• Wearing soft and breathable clothing
• Protecting exposed skin from cold wind

Some patients notice improvement with moderate sunlight, but excessive ultraviolet exposure and sunburn may trigger new plaques or worsen existing symptoms.

Can smoking and alcohol worsen psoriasis?

Smoking is associated with inflammation and may make psoriasis more difficult to manage in some patients.

Frequent or excessive alcohol consumption may also contribute to flare-ups and can interfere with certain prescription treatments.

Patients taking medication for psoriasis should ask their healthcare provider whether alcohol may interact with their treatment.

Can hormonal changes affect psoriasis?

Some patients notice changes in symptoms during puberty, pregnancy, after childbirth, or around menopause. Hormonal changes do not affect every patient in the same way.

Patients who are pregnant, breastfeeding, or planning a pregnancy should review all prescription medications, topical products, and supplements with their healthcare provider.

Can skin care products irritate psoriasis?

Harsh skin care products may increase dryness, irritation, or inflammation. Products containing strong fragrance, alcohol, abrasive particles, or aggressive exfoliating ingredients may be difficult for sensitive skin to tolerate.

A gentle routine may include:

• A mild, fragrance-free cleanser
• A thick moisturizer or ointment
• Warm rather than hot water
• Patting the skin dry instead of rubbing
• Daily sun protection
• Products recommended by a dermatologist

Patients should avoid picking, scratching, or forcefully removing scales because this may damage the skin and increase inflammation.

Does diet trigger psoriasis?

There is no single food or universal diet that causes or cures psoriasis in every patient. Some people notice individual food-related patterns, but these experiences vary.

A balanced diet and healthy weight may support general health and make certain treatments easier to manage. Restrictive diets, herbal products, and supplements should be discussed with a healthcare professional, especially when prescription medications are being used.

How can you identify personal triggers?

Keeping a symptom diary may help patients identify patterns. Useful information to record includes:

• The date a flare began
• Recent illnesses or infections
• Stressful events
• New medications or dosage changes
• Skin injuries or sunburn
• Changes in weather
• Smoking or alcohol use
• Changes in skin care products
• Sleep quality and overall health

This information can be reviewed with a medical provider to guide treatment and prevention strategies.

How is psoriasis medically treated?

Treatment depends on the type and severity of psoriasis, the location of the plaques, the patient's medical history, and whether the joints are affected.

A healthcare professional may recommend:

• Prescription topical medications
• Medically supervised ultraviolet phototherapy
• Oral medications
• Injectable biologic medications
• Treatment for joint pain or stiffness
• A combination of therapies

Medically supervised ultraviolet phototherapy is different from tanning beds, IPL photofacials, Pico lasers, and ordinary cosmetic laser treatments.

Can Pico laser or IPL treat active psoriasis?

Pico lasers, IPL photofacials, and cosmetic hyperpigmentation procedures should not be presented as standard treatments or cures for active psoriasis.

Applying cosmetic light or laser energy to inflamed, irritated, or actively affected skin may increase discomfort or cause additional skin changes. Medical clearance and a professional assessment are necessary before any cosmetic procedure is considered.

After psoriasis is medically controlled, some patients may have residual discoloration or unrelated cosmetic concerns. These concerns should be evaluated separately.

Information about treatment for suitable pigmentation concerns is available through  Hyperpigmentation Treatment  ,  but active psoriasis should not be treated as ordinary hyperpigmentation.

Patients may also review  IPL & Laser Skin Resurfacing    for information about cosmetic light and laser procedures used for other appropriate skin concerns.

When should you contact a medical professional?

Arrange a medical evaluation when psoriasis is spreading, painful, difficult to control, affecting sleep, or interfering with daily activities.

Prompt medical attention may be necessary when symptoms include:

• Rapidly spreading redness
• Widespread peeling
• Severe tenderness
• Pus-filled bumps
• Fever or chills
• Signs of infection
• New joint pain, swelling, or stiffness
• Eye pain or vision changes
• A severe reaction after starting or stopping medication

Take a personalized approach to psoriasis management

Psoriasis triggers differ from one patient to another, and it may not be possible to prevent every flare. Identifying personal triggers, following a prescribed medical plan, protecting the skin, and attending regular follow-up appointments may help reduce the frequency or severity of symptoms.
