What Can Cause Psoriasis to Flare Up?

Living with psoriasis can be challenging, especially when an unexpected flare causes itching, scaling, discomfort, or visible changes in the skin.

Psoriasis is a chronic immune-mediated condition. Symptoms may improve for a period of time and then return after exposure to certain triggers. Because triggers vary from person to person, identifying individual patterns can be an important part of long-term management.

Psoriasis should be evaluated and managed by a qualified medical professional. Cosmetic skin treatments should not replace diagnosis, prescription treatment, or ongoing care from a dermatologist or other appropriate healthcare provider.

What is psoriasis?

Psoriasis develops when immune system activity causes skin cells to multiply more rapidly than usual. The extra skin cells build up on the surface, creating inflamed, thickened, or scaly areas.

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

Symptoms and appearance vary among patients and across different skin tones. Plaques may appear red, pink, purple, brown, gray, or darker than the surrounding skin. Scaling may look white or silvery.

Psoriasis is not contagious. It cannot be spread through touching, sharing personal items, or close contact.

What is a psoriasis flare-up?

A flare-up is a period when existing psoriasis becomes more active or new areas appear. Patients may notice increased itching, scaling, inflammation, cracking, soreness, or changes in the size and number of plaques.

A flare may last for days, weeks, or longer. The severity and duration depend on the patient's type of psoriasis, medical treatment, general health, and exposure to personal triggers.

Can stress trigger psoriasis?

Emotional and physical stress are commonly reported psoriasis triggers. Stress can influence inflammatory activity in the body and may make itching or discomfort feel more intense.

Psoriasis itself can also create stress, especially when plaques are uncomfortable or visible. This may create a cycle in which stress contributes to a flare and the flare causes additional emotional strain.

Helpful stress-management strategies may include:

• Maintaining a regular sleep schedule
• Practicing breathing or relaxation exercises
• Participating in appropriate physical activity
• Using meditation or mindfulness techniques
• Talking with a mental health professional when needed
• Seeking support from family, friends, or patient groups

Can infections cause psoriasis to flare?

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

Other illnesses may also be associated with worsening symptoms. Patients should contact a healthcare professional when they have signs of infection, such as fever, persistent sore throat, unusual fatigue, or worsening skin symptoms.

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

Can skin injuries trigger new psoriasis plaques?

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

Possible triggers include:

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

Protecting the skin and treating minor injuries gently may help reduce unnecessary irritation.

Can medications worsen psoriasis?

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

Abruptly stopping some systemic medications, including certain corticosteroids, may also cause serious worsening.

Patients should not stop or change a prescription medication without speaking with the healthcare professional who prescribed it. A dermatologist and prescribing clinician can work together to assess whether a medication may be contributing to the flare and whether an alternative is appropriate.

How can weather affect psoriasis?

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

Some patients improve during warmer, more humid months, but excessive sunlight and sunburn can make psoriasis worse.

Helpful cold-weather habits may include:

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

Can smoking or alcohol contribute to flare-ups?

Smoking may increase inflammation and is associated with more difficult-to-control psoriasis in some patients. Frequent or excessive alcohol consumption may also worsen symptoms and interfere with certain psoriasis treatments.

Alcohol may interact with prescription medications, so patients should discuss safe limits with their healthcare provider.

Reducing smoking and excessive alcohol use may support overall health as well as psoriasis management.

Can hormonal changes affect psoriasis?

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

Pregnant patients or those planning a pregnancy should review all psoriasis medications and topical products with their healthcare provider, because some treatments may not be appropriate during pregnancy or breastfeeding.

Can skin care products cause a flare?

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

A gentle skin care routine may include:

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

Patients should avoid picking or forcefully removing scales, because this can injure the skin and increase inflammation.

Does diet cause psoriasis flare-ups?

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

Maintaining a balanced eating plan and a healthy weight may support general health and may make certain treatments easier to manage. Restrictive diets or supplements should be discussed with a healthcare professional, particularly when prescription medication is being used.

How can you identify your personal triggers?

Keeping a symptom record may help identify patterns. Patients can record:

• When a flare begins
• 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 and general health

The record can be reviewed with a dermatologist to help guide treatment and prevention strategies.

How is psoriasis medically treated?

Psoriasis treatment depends on its type, severity, location, symptoms, medical history, and whether the joints are affected.

A medical professional may recommend:

• Prescription topical medications
• Medically supervised phototherapy
• Oral medications
• Injectable biologic medications
• Treatment for associated joint symptoms
• A combination of therapies

Medically supervised phototherapy uses controlled ultraviolet light. It is different from tanning beds, IPL photofacials, and ordinary cosmetic laser procedures.

Can cosmetic laser treatment cure psoriasis?

Cosmetic lasers and IPL photofacials should not be presented as a cure or standard treatment for psoriasis. Active plaques require appropriate medical assessment, and applying heat or light-based cosmetic energy to inflamed skin may cause irritation.

Once psoriasis is medically controlled, some patients may have lingering discoloration or unrelated cosmetic concerns. These should be assessed separately.

Patients seeking care for residual dark marks may review  Hyperpigmentation Treatment  ,  but active psoriasis should not be treated as ordinary hyperpigmentation.

Information about cosmetic light and laser procedures for other appropriate skin concerns is available through  IPL & Laser Skin Resurfacing  .  Medical clearance and a professional skin assessment are necessary before treating skin with a history of psoriasis.

When should you contact a medical professional?

Patients should arrange medical evaluation when psoriasis is spreading, painful, difficult to control, interfering with sleep, or affecting daily activities.

Prompt medical attention is especially important when symptoms include:

• Rapidly spreading redness
• Widespread peeling or 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 skin health

Psoriasis triggers differ between patients, and avoiding every flare may not be possible. However, identifying personal triggers, following the prescribed treatment plan, protecting the skin, and maintaining regular medical follow-up may help reduce the frequency or severity of symptoms.
