Psoriasis
Affecting the skin but rooted in the immune system, this chronic condition moves through unpredictable cycles of flare-ups and remission. Severity varies widely, but with consistent management, patients can control inflammation and maintain long-term skin clearance.
What Is Psoriasis?
Psoriasis is a chronic skin disease that accelerates the natural growth cycle of skin cells and causes cells to build up rapidly on the surface of the skin, forming thick, silvery scales and itchy, dry, red patches that can be painful.
While the condition is rooted in genetics, environmental factors play a massive role in how often and how severely the condition presents.
Expert Management
At Core Dermatology, we frequently observe that Denver’s high altitude, low-humidity climate increases the severity of flare-ups for local patients compared to those living in more humid regions. This has allowed our team to become experts in psoriasis treatment.
Common Symptoms of Psoriasis
Symptoms can vary depending on the type of psoriasis you have, but most patients experience cycles where symptoms flare up for weeks or months and then subside. Common signs include:
- Red patches of skin covered with thick, silvery scales.
- Small scaling spots (commonly seen in children).
- Dry, cracked skin that may bleed or itch.
- Itching, burning, or soreness around the patches.
- Thickened, pitted, or ridged nails.
- Swollen and stiff joints.
The most common type of psoriasis is plaque psoriasis which manifests with large plaques, commonly affecting the elbows, knees, and lower back.
What Causes Psoriasis?
Psoriasis is caused by a malfunction in the immune system where T cells (a type of white blood cell) trigger inflammatory signaling in the skin. This triggers the body to produce new skin cells in days rather than weeks, leading to the characteristic buildup of thick, scaly plaques.
While genetics provide the foundation for the disease, external factors known as “triggers” usually activate the condition. Common triggers include:
- Stress: High stress levels can induce the first outbreak or worsen existing ones.
- Injury: Cuts, scrapes, or severe sunburns (the Koebner phenomenon).
- Infections: Such as strep throat.
- Weather: Cold, dry conditions.
How Does Denver’s Climate Impact Psoriasis?
In cold dry climates like Denver’s, we find that weather is a primary trigger for our patients. Colorado’s rapid temperature shifts and distinct lack of moisture in the air are significant factors that can activate the condition or make management more difficult without professional intervention.
In the arid environment of Denver, the symptom of dry, cracked skin is often the first warning sign. Many patients initially mistake this for simple “winter dry skin” before seeking a professional diagnosis.
Types of Psoriasis
Each variation of the disease should prompt a customized treatment approach based on the severity and location of the breakout.
Plaque Psoriasis
This is the most common form of the disease. It causes dry, raised, red skin lesions (plaques) covered with silvery scales. The plaques might be itchy or painful and can occur anywhere on the body.
Guttate Psoriasis
This type primarily affects young adults and children. It is usually triggered by a bacterial infection such as strep throat. It is marked by small, water-drop-shaped, scaling lesions on the trunk, arms, or legs.
Inverse Psoriasis
This mainly affects the skin in the armpits, groin, under the breasts, and around the genitals. Inverse psoriasis causes smooth patches of red, inflamed skin that worsen with friction and sweating.
Pustular Psoriasis
This uncommon form can occur in widespread patches or in smaller areas on your hands, feet, or fingertips. It generally develops quickly, with pus-filled blisters appearing hours after your skin becomes red and tender.
Treatment Options for Psoriasis
Medical treatment for psoriasis typically follows a “step-up” approach, starting with the mildest treatments and progressing to stronger therapies only if necessary. The goal of any treatment is to reduce inflammation, stop the skin cells from growing so quickly, relieve symptoms such as scaling and itch, and maintain long-term disease control.
Topical Therapies
-
Corticosteroids
The most frequently prescribed medications for treating mild to moderate psoriasis. They work by reducing inflammation and relieving itching.
-
Vitamin D Analogues
Synthetic forms of Vitamin D that slow down the growth of skin cells.
-
Retinoids
Derived from Vitamin A, these can decrease inflammation but may increase sensitivity to sunlight.
Phototherapy (Light Therapy)
-
Broadband & Narrowband UVB
Specific wavelengths of light used to treat single patches or widespread psoriasis.
-
Excimer Laser
A targeted laser for chronic, localized plaques (often on elbows or knees) that doesn’t affect the surrounding healthy skin.
Systemic Medications
-
Biologics
These are protein-based drugs (usually injections) that target specific parts of the immune system that fuel the psoriasis.
-
Oral Retinoids
Used to reduce the production of skin cells.
-
Methotrexate
A traditional medication that suppresses the immune system and slows down skin cell production.
Tips to Help Manage Psoriasis in Denver’s Climate
Living in the Rocky Mountains requires specific lifestyle adjustments to keep psoriasis under control. Based on our experience treating patients in Denver, we recommend the following:
-
Humidify Your Home
The dry mountain air sucks moisture from the skin. Running a whole-home humidifier or portable units in bedrooms helps maintain the skin barrier.
-
Smart Sun Exposure
Denver boasts 300 days of sunshine. While moderate sunlight (Vitamin D) can improve symptoms, sunburns can trigger a flare (Koebner phenomenon). Use broad-spectrum sunscreen on non-affected areas.
-
Heavy Moisturizing
In our climate, lotions often aren’t enough. We advise patients to switch to thicker ointments or creams, especially during winter, to lock in moisture more effectively.
Frequently Asked Questions (FAQ) About Psoriasis
Is psoriasis contagious?
No, it is not contagious. You cannot catch psoriasis from touching someone, sharing towels, or swimming in the same pool. It is an immune mediated skin disease, not an infection.
Why does my psoriasis get worse in the winter in Denver?
Cold air holds less moisture than warm air. When combined with indoor heating, this environment dries out the skin barrier rapidly, triggering inflammation and itching.
Is there a cure for my psoriasis?
There is currently no medical cure for psoriasis, but our dermatologists can help you achieve “clear” or “almost clear” skin. With consistent care and an appropriate treatment plan, most patients can remain symptom-free for many years.
