What Is Psoriasis?

Psoriasis is a chronic immune-mediated inflammatory skin disease that causes skin cells to grow much faster than normal.

Common types include:

• Plaque Psoriasis
• Scalp Psoriasis
• Nail Psoriasis
• Guttate Psoriasis
• Inverse Psoriasis
• Pustular Psoriasis

Common symptoms include:

• Thick red plaques
• Silvery-white scales
• Itching
• Dry cracked skin
• Skin pain
• Nail thickening or pitting
• Scalp flaking

Psoriasis is not contagious and cannot be spread through skin contact. It often follows a lifelong course with periods of flare-ups and remission. Stress, infections, skin injury, certain medications, alcohol, and smoking may trigger or worsen symptoms.

How Psoriasis Treatment Works

After evaluating the type, severity, body surface area involved, and any associated conditions, your dermatologist develops an individualized treatment plan.

Treatment options may include:

• Medical Moisturizers
• Topical Corticosteroids
• Vitamin D Analogues
• Topical Retinoids
• Calcineurin Inhibitors (selected areas)
• Salicylic Acid Preparations
• Narrowband UVB Phototherapy
• Excimer Laser (localized plaques)
• Oral Systemic Medications
• Biologic Therapy

Treatment aims to:

• Slow excessive skin cell growth
• Reduce inflammation
• Relieve itching
• Clear plaques
• Prevent flare-ups
• Improve long-term quality of life

Topical therapy remains the foundation for mild disease, while phototherapy, systemic medications, or biologics are considered for moderate to severe psoriasis.

Mild vs Moderate-to-Severe Psoriasis

Mild Psoriasis

Often treated with:

• Moisturizers
• Topical corticosteroids
• Vitamin D creams
• Salicylic acid
• Topical retinoids

Moderate-to-Severe Psoriasis

May require:

• Narrowband UVB phototherapy
• Excimer laser
• Oral medications
• Biologic therapy
• Combination treatment

The treatment plan depends on disease severity, body surface area involved, lesion location, previous treatments, and whether psoriatic arthritis or other medical conditions are present.

Combination Treatments

Psoriasis treatment may be combined with:

• Narrowband UVB Phototherapy
• Excimer Laser
• Medical Moisturizers
• Topical Prescription Therapy
• Biologic Therapy
• Psoriatic Arthritis Evaluation
• Lifestyle and Trigger Management

What Happens During Treatment?

Treatment generally includes:

• Dermatology consultation
• Skin examination
• Disease severity assessment
• Review of medical history
• Individualized treatment plan
• Prescription medications (when indicated)
• Regular follow-up

Most consultations take approximately 20–40 minutes.

Recovery and Long-Term Management

Psoriasis is a chronic condition that requires ongoing management rather than a one-time treatment.

Patients are encouraged to:

• Moisturize daily
• Use medications consistently
• Avoid known triggers
• Maintain a healthy lifestyle
• Attend regular follow-up visits

Many patients begin noticing improvement within 2–6 weeks, although biologic therapy and phototherapy may continue improving results over several months.

How Long Do Results Last?

There is currently no permanent cure for psoriasis, but modern treatments can achieve prolonged disease control and, in many patients, near-complete skin clearance. Long-term maintenance therapy helps reduce flare-ups and maintain remission.

Frequently Asked Questions

Can psoriasis be cured permanently?

No. Psoriasis is a chronic immune-mediated disease, but modern treatments can effectively control symptoms, reduce flare-ups, and allow many patients to achieve long periods of remission.

What is the best treatment for psoriasis?

The best treatment depends on the severity and type of psoriasis. Mild cases often respond to topical medications, while moderate to severe disease may require phototherapy, oral medications, biologics, or combination therapy.

Is psoriasis contagious?

No. Psoriasis cannot be spread from one person to another through physical contact, sharing towels, or other forms of close interaction.

Can stress trigger psoriasis?

Yes. Emotional stress is one of the most common triggers for psoriasis flare-ups, along with infections, skin injuries, smoking, alcohol, and certain medications.

Is phototherapy effective for psoriasis?

Yes. Narrowband UVB phototherapy is an established treatment for moderate psoriasis and can significantly improve skin lesions when performed under medical supervision.

When are biologic medications recommended?

Biologics are generally recommended for patients with moderate to severe psoriasis who have not achieved adequate control with topical treatments, phototherapy, or conventional systemic medications.
