Psoriasis is a chronic autoimmune skin condition that causes your skin cells to multiply too quickly, resulting in a buildup of red, scaly patches. These patches can be itchy, painful, and sometimes even bleed. The good news? It’s not contagious—you can’t catch it from someone else. It often shows up on areas like your elbows, knees, scalp, or lower back, but it can appear anywhere on your body.

*Types of Psoriasis -
There are several types of psoriasis, each with its own
unique symptoms:
- **Plaque Psoriasis**: The most common type, featuring
raised, inflamed patches covered with silvery-white scales.
- **Guttate Psoriasis**: Small, dot-like spots, often
triggered by infections like strep throat.
- **Inverse Psoriasis**: Red, shiny lesions in skin folds
(like armpits or under the breasts).
- **Pustular Psoriasis**: White, pus-filled blisters
surrounded by red skin.
- **Erythrodermic Psoriasis**: A rare, severe form causing
widespread redness and shedding of the skin.

What Causes It?
Psoriasis happens when your immune system goes haywire and
attacks healthy skin cells by mistake. While the exact cause isn’t fully
understood, a few factors play a role:
- **Genetics**: If it runs in your family, you’re more likely
to develop it.
- **Triggers**: Stress, skin injuries (like cuts or sunburn),
infections, and certain medications (like beta-blockers) can set it off or make
it worse.

*Treatment Options -
There’s no cure for psoriasis, but plenty of treatments can
help manage it:
- **Topical Treatments**: Creams and ointments like
corticosteroids or vitamin D analogs to reduce inflammation and slow skin cell
growth.
- **Phototherapy**: Controlled exposure to UV light to calm
the immune response.
- **Systemic Treatments**: Pills or injections (like
methotrexate or biologics) for more severe cases.
The right treatment depends on the type and severity of your
psoriasis, so it’s best to work with a dermatologist to figure out what works
for you.

*Living with Psoriasis -
Psoriasis isn’t just a skin problem—it can affect your whole
life. Physically, it can cause discomfort or pain. Emotionally, it might lead
to embarrassment, anxiety, or depression. It’s also linked to other health
issues like:
- **Psoriatic Arthritis**: Joint pain and stiffness.
- **Heart Disease** and **Diabetes**: Increased risk in some
cases.
*Tips to Manage It:
- Keep your skin moisturized to reduce irritation.
- Avoid triggers like stress, smoking, or harsh soaps.
- Maintain a healthy weight—extra pounds can worsen symptoms.
Psoriasis is a lifelong condition, but with the right
approach, you can keep it under control. It’s more than skin deep, so don’t
hesitate to seek support from a healthcare provider to improve both your skin
and your quality of life.
*Key Points -
- Psoriasis is a chronic skin condition causing red, scaly
patches, likely due to an overactive immune system.
- It seems likely that genetics and triggers like stress or
infections play a role, though research is ongoing.
- Treatment options include creams, light therapy, and
medications, with new options like roflumilast foam approved in 2025.
- The evidence leans toward psoriasis being manageable but
not curable, with varying severity and impact on quality of life.

*What is Psoriasis?
Psoriasis is a long-term skin condition where the immune
system causes skin cells to multiply too quickly, leading to thick, red, and
scaly patches. These patches can be itchy or sore and often appear on the
elbows, knees, scalp, or lower back. It’s not contagious, and while it can
affect anyone, it’s most common in adults aged 20–30 or 50–60.
---
*Causes and Triggers -
Research suggests psoriasis is an autoimmune disease, where
the body’s immune system attacks healthy skin cells. Genetics seem to play a
role, as it often runs in families, and triggers like stress, skin injuries,
infections (e.g., strep throat), or certain medications can worsen symptoms.
---
*Treatment Options -
Treatments aim to manage symptoms and include:
- **Topical treatments**: Creams like corticosteroids to
reduce inflammation.
- **Phototherapy**: UV light exposure to calm the immune
system.
- **Systemic treatments**: Pills or injections for severe
cases, such as biologics.
- In 2025, new treatments like roflumilast foam were approved
for plaque psoriasis, offering more options for patients.

Comprehensive Overview of Psoriasis -
Psoriasis is a chronic, non-contagious autoimmune skin
condition characterized by the rapid buildup of skin cells, leading to the
formation of thick, red, and scaly patches. These patches, often covered with
silvery-white or gray scales, can appear on various parts of the body, most
commonly the elbows, knees, scalp, and lower back. The condition affects
approximately 2% of people in the UK and 7.5 million adults in the US, with
symptoms typically starting between ages 15 and 25, though it can begin at any
age. It impacts men and women equally and varies in severity, from minor
irritation to significant quality-of-life challenges.
*Types of Psoriasis -
Psoriasis manifests in several forms, each with distinct
features:
- **Plaque Psoriasis**: The most prevalent type, accounting
for about 90% of cases, presents as raised, red patches with silvery-white
scales. On lighter skin, these appear red with white scales; on medium skin
tones, they may be coral or salmon-colored with silvery-white scales; and on
darker skin tones, they can be dark brown or purplish with gray scales.
- **Guttate Psoriasis**: Characterized by small, drop-shaped
lesions, often triggered by infections like strep throat.
- **Inverse Psoriasis**: Appears as smooth, red patches in
skin folds, such as the armpits or groin, without the typical scaling.
- **Pustular Psoriasis**: Features white, pus-filled blisters
surrounded by red skin, commonly on the hands and feet, and is non-infectious.
- **Erythrodermic Psoriasis**: A rare, severe form causing
widespread redness and shedding of the skin, which can be life-threatening.
It’s possible to have more than one type simultaneously or
experience different types over a lifetime, with treatment varying based on the
type and location.
*Causes and Triggers -
Psoriasis is classified as an immune-mediated disease, where
the immune system mistakenly attacks healthy skin cells, causing inflammation.
The underlying mechanism involves the immune system reacting to skin cells,
leading to their rapid multiplication and shedding every 3–4 days, compared to
the normal 10–30 days. While the exact cause is not fully understood, research suggests
a combination of genetic and environmental factors:
- **Genetics**: If one identical twin has psoriasis, the
other is three times more likely to be affected than if they were
non-identical, indicating a strong genetic predisposition. It often runs in
families, with studies showing a hereditary component.
- **Triggers**: Various factors can exacerbate or trigger
psoriasis, including:
- Stress, which can
worsen symptoms due to its impact on the immune system.
- Skin injuries, such
as cuts, burns, or sunburn, known as the Koebner phenomenon, where psoriatic
changes appear at the injury site.
- Infections,
particularly streptococcal infections, which can trigger guttate psoriasis.
- Medications like
beta-blockers, NSAIDs, and lithium, which may worsen the condition.
- Lifestyle factors,
such as smoking, obesity, and excessive alcohol consumption, are also linked to
increased severity.
Symptoms often worsen during winter, possibly due to reduced
sunlight exposure, and can fluctuate, with periods of flare-ups followed by
remission.
*Symptoms and Impact -
The symptoms of psoriasis can vary widely but commonly
include:
- Red, pink, or purple patches of skin, depending on skin
tone, covered with scales that may be silvery-white, gray, or darker brown.
- Dry, cracked skin that may bleed, especially if scratched.
- Itching, burning, or soreness, which can be particularly
distressing.
- Thickened, pitted, or ridged nails, affecting most people
at some point.
- In severe cases, joint pain and stiffness, indicative of
psoriatic arthritis, which affects about 30% of psoriasis patients.
Psoriasis is more than a skin condition; it can significantly
impact emotional well-being, leading to embarrassment, anxiety, or depression.
It’s also associated with increased risks of other health issues, such as heart
disease, diabetes, and inflammatory bowel disease, due to chronic inflammation.
*Diagnosis -
Diagnosis is typically based on the appearance of the skin
and medical history, with no specific tests required. Dermatologists may
perform a biopsy in unclear cases to rule out other conditions like eczema. The
Psoriasis Area and Severity Index (PASI) is often used to assess severity,
considering the extent of redness, thickness, and scaling.
*Treatment Options -
While there is no cure for psoriasis, a range of treatments
can manage symptoms and improve quality of life. The choice depends on the
type, severity, and individual patient factors:
- **Topical Treatments**: These are often first-line for mild
psoriasis and include:
- Corticosteroids,
such as hydrocortisone, to reduce inflammation and itching.
- Vitamin D analogs,
like calcipotriol, to slow skin cell growth.
- Retinoids, derived
from vitamin A, to normalize skin cell production.
- Salicylic acid to
remove scales and smooth the skin.
- **Phototherapy**: Involves controlled exposure to UV light,
either UVB or UVA, often combined with psoralen (PUVA therapy). It helps calm
the immune response and is effective for moderate psoriasis.
- **Systemic Treatments**: Used for moderate to severe cases,
these include:
- Oral medications
like methotrexate, which suppresses the immune system, or cyclosporine, an
immunosuppressant.
- Biologics, such as
adalimumab (Humira) or etanercept (Enbrel), which target specific parts of the
immune system, particularly TNF-alpha or IL-17/IL-23 pathways. As of recent
reports, there are over 13 FDA-approved biologic options for moderate to severe
psoriasis.
- **Emerging Treatments in 2025**: The landscape of psoriasis
treatment is evolving, with several new options showing promise:
- **Roflumilast Foam
(Zoryve)**: Approved by the FDA on May 22, 2025, for plaque psoriasis in adults
and adolescents aged 12 and older, particularly for scalp and body psoriasis. It’s
a topical foam already approved for other uses, offering a new option for
topical treatment.
- **Icotrokinra**: A
first-in-class oral peptide that selectively blocks the IL-23 receptor, showing
potential to set a new standard in plaque psoriasis treatment, with positive
results reported in early 2025.
- **AC-201**: A
selective TYK2/JAK1 inhibitor from Accropeutics, with phase 2 results showing
74% of patients achieving PASI-75 at 50 mg twice daily, indicating strong
efficacy.
- **AX-158**: Artax
Biopharma’s phase 2a results for plaque psoriasis were presented at SID2025,
suggesting another potential treatment option.
- **Tildrakizumab**:
Demonstrated efficacy for nail psoriasis, with significant improvements in
clinical scores at week 28, as reported at AAD 2025.
- **Imsidolimab**:
Vanda Pharmaceuticals added this anti-IL-36 antibody to its late-stage
portfolio for Generalized Pustular Psoriasis (GPP), with plans for marketing
approval.
- Additionally, a
light-activated drug, MRS7787, showed promise in modulating the immune system
for psoriasis treatment, with studies published in early 2025.
These advancements, particularly in biologics, small
molecules, and personalized medicine, are reshaping psoriasis management,
offering patients more tailored and effective options.
*Living with Psoriasis -
Managing psoriasis involves more than medical treatment;
lifestyle adjustments can significantly impact symptom control:
- **Skin Care**: Regular moisturizing helps reduce dryness
and irritation. Avoid harsh soaps and hot water, which can exacerbate symptoms.
- **Trigger Management**: Identifying and avoiding triggers,
such as stress (e.g., through mindfulness or therapy) or smoking, can help
prevent flare-ups.
- **Healthy Lifestyle**: Maintaining a healthy weight is
crucial, as obesity can worsen psoriasis. A balanced diet rich in
anti-inflammatory foods, like omega-3 fatty acids, may also help.
- **Support and Mental Health**: The emotional toll of
psoriasis can be significant, with many experiencing embarrassment or anxiety.
Support groups, counseling, or connecting with others via platforms like the
National Psoriasis Foundation can provide relief.
Psoriasis is also linked to comorbidities, such as psoriatic
arthritis (affecting joints), cardiovascular disease, and diabetes,
necessitating regular health check-ups to monitor for related conditions.
*Research and Future Directions -
The field of psoriasis research is active, with ongoing
studies exploring the role of the microbiome, epigenetics, and novel
therapeutic targets. The 2025 advancements, such as the approval of roflumilast
foam and promising results for Icotrokinra and AC-201, indicate a trend toward
more targeted and patient-friendly treatments. Patient-reported outcomes and
long-term safety data, like the five-year results for Sotyktu
(deucravacitinib), are also shaping treatment guidelines.
In summary, psoriasis is a complex, chronic condition with a
range of treatment options, from traditional topicals to cutting-edge biologics
and new approvals in 2025. While it remains incurable, the evolving landscape
offers hope for better management and improved quality of life for those
affected.
