Psoriasis is a chronic autoimmune skin disorder that speeds up the life cycle of skin cells, causing them to build up rapidly and form thick, scaly patches. These raised plaques are often itchy, inflamed, and uncomfortable—and for many, they come and go in unpredictable flare-ups.
At Metropolis Dermatology in Pasadena, we offer advanced psoriasis treatments designed to reduce inflammation, slow down skin cell production, and provide lasting symptom relief. Our featured solution, the XTRAC Excimer Laser, is clinically proven to treat even the most stubborn plaques with precision.
What Is Psoriasis?
Psoriasis develops when the body’s immune system misfires, attacking healthy skin cells as if they were threats. This immune response dramatically increases the rate of skin cell growth. Instead of shedding naturally, skin cells pile up on the surface, resulting in flaky, red, or silvery plaques that may itch or crack.
What Triggers Psoriasis?
Psoriasis is a complex condition influenced by a range of internal and external factors. Common triggers include:
Genetic predisposition
Those with a family history of psoriasis are more likely to develop the condition.
Infections
Illnesses like strep throat can spark new flare-ups or worsen existing plaques.
Stress
Emotional and physical stress can contribute to or intensify breakouts.
Environmental factors
Dry, cold weather can cause skin to dry out and trigger inflammation.
Skin trauma
Scrapes, cuts, bug bites, or even sunburns can prompt new lesions to form—a phenomenon known as the Koebner response.
Common Psoriasis Symptoms
Psoriasis can appear in different forms, but common symptoms include:
- Thick, scaly patches of skin often found on the elbows, knees, scalp, or lower back
- Cracked or dry skin that may bleed or feel sore
- Persistent itching or burning, sometimes accompanied by redness and tenderness
- Nail changes, such as pitting, discoloration, or nail plate lifting
- Joint stiffness and swelling in people with psoriatic arthritis
XTRAC Excimer Laser Therapy for Psoriasis
Our Pasadena clinic proudly offers the XTRAC Excimer Laser, a non-invasive, FDA-approved light therapy that delivers narrowband UVB light directly to psoriasis plaques—without harming surrounding healthy tissue. This precision approach helps reduce redness, scaling, and plaque thickness while minimizing side effects associated with traditional phototherapy.
Why Patients Choose XTRAC Laser Treatment
- Pinpoint precision that treats only the affected areas
- Fewer side effects compared to full-body light treatments
- Highly effective on difficult-to-reach areas like the scalp, elbows, and knees
- Fast treatment times, with most sessions lasting just a few minutes
- Longer-lasting relief between flare-ups with consistent use
- FDA-approved technology backed by clinical research
- No downtime or recovery period—resume normal activity right away
Frequently Asked Questions About Psoriasis & Laser Treatment
Can psoriasis be permanently cured?
There is currently no cure for psoriasis. However, treatments like XTRAC Excimer Laser can manage symptoms and help reduce the frequency and severity of flare-ups.
Is psoriasis contagious?
No—psoriasis is not an infectious condition. It cannot be spread through skin contact, shared items, or proximity to someone with the condition.
How many XTRAC laser sessions will I need?
Most patients benefit from multiple treatments over several weeks. The number of sessions depends on the severity of the condition and how the skin responds to therapy.
Can psoriasis affect the joints?
Yes. A subset of individuals with psoriasis may develop psoriatic arthritis, which causes inflammation, stiffness, and pain in the joints—especially in the fingers, toes, and spine.
Does nutrition play a role in managing psoriasis?
While no specific diet can cure psoriasis, reducing inflammatory foods, maintaining a healthy weight, and avoiding known triggers may help minimize flare-ups and support overall skin health.
