What Plaque Psoriasis Looks Like And Treatment Options

Plaque psoriasis is a common chronic skin condition characterized by inflamed, red patches covered with silvery scales. Understanding its appearance and the available treatment options is essential for effective management.


Plaque psoriasis manifests as raised, inflamed, red patches on the skin, covered with silvery scales. It commonly affects the elbows, knees, scalp, and lower back.

Detailed Analysis

Common Signs Of Plaque Psoriasis

Symptom Description
Red Patches Raised, inflamed red patches on the skin, commonly found on elbows, knees, scalp, and lower back.
Silvery-White Scales Dead skin cells that build up, creating a silver or white layer on top of red patches.
Dry, Cracked Skin Affected areas may become very dry and crack, sometimes leading to bleeding.
Itching and Burning Intense itching, burning, or soreness in the affected areas.
Thickened and Pitted Nails Nails may become thickened, pitted, or ridged, and in some cases, may lift from the nail bed (onycholysis).
Joint Pain and Stiffness Up to 30% of people with psoriasis develop psoriatic arthritis, causing joint pain, stiffness, and swelling.

Commonly Affected Areas and Symptoms

Body Part Common Symptoms

What Cause Plaque Psoriasis?

Genetic Factors

  • Family History: Having a family member with psoriasis significantly increases the risk. About 30% of people with psoriasis have a close relative with the condition .
  • Specific Genes: Certain genes are associated with the immune system and its regulation, such as the HLA-Cw6 gene, which is strongly linked to plaque psoriasis .

Immune System

  • Autoimmune Response: Plaque psoriasis is an autoimmune disease where the body’s immune system mistakenly attacks healthy skin cells. This triggers an accelerated skin cell production cycle, leading to the buildup of cells on the surface of the skin .
  • T-Cells: T-cells, a type of white blood cell, play a critical role. In psoriasis, T-cells are mistakenly activated and become so active that they trigger other immune responses, resulting in inflammation and rapid turnover of skin cells .

Environmental Triggers

Common Triggers

  • Infections: Certain infections, such as streptococcal throat infections, can trigger psoriasis flare-ups​
  • Skin Injuries: Injuries to the skin, including cuts, scrapes, or sunburn, can trigger a reaction known as the Koebner phenomenon, where new plaques form at the site of the injury​ 
  • Stress: High levels of stress can exacerbate or trigger psoriasis symptoms​ 
  • Climate: Cold, dry weather can worsen psoriasis, while warm, sunny climates might improve symptoms.

Lifestyle Factors

  • Diet: While diet alone does not cause psoriasis, certain foods may exacerbate symptoms. Alcohol and a diet high in fatty foods can worsen the condition​ 
  • Smoking: Smoking is a risk factor for the development and exacerbation of psoriasis. It can also reduce the effectiveness of treatment​ 
  • Medications: Certain medications, such as lithium, beta-blockers, and antimalarial drugs, can trigger or worsen psoriasis symptoms .

Appearance of Plaque Psoriasis

Plaque psoriasis is the most common form of psoriasis, making up about 80-90% of all psoriasis cases. Its distinctive appearance includes:

  • Red Patches: Raised and inflamed areas of skin.
  • Silvery-White Scales: Dead skin cells build up, creating a silver or white layer on top of the red patches.
  • Thickness: Lesions are often thick and can be painful or itchy.
  • Size and Shape: The plaques can vary in size and shape, often merging to cover larger areas.

Questions and Answers (QA)

Q: What triggers plaque psoriasis?

A: Triggers can include stress, skin injuries, infections, and certain medications. Genetics also play a crucial role in its development.

Q: Is plaque psoriasis contagious?

A: No, plaque psoriasis is not contagious. It is an autoimmune condition that affects the skin.

Q: Can diet affect plaque psoriasis?

A: Yes, a balanced diet and maintaining a healthy weight can help manage symptoms. Certain foods may exacerbate or alleviate symptoms.

Treatment Options

Plaque psoriasis is a chronic autoimmune condition characterized by the rapid buildup of skin cells. This buildup of cells creates scales and red patches that are sometimes itchy and painful. Understanding what plaque psoriasis looks like and the available treatment options can help those affected manage the condition more effectively. In this guide, we explore the appearance of plaque psoriasis and four treatment options that can help alleviate its symptoms.

1Topical Treatments
0 votes
Topical treatments are often the first line of defense in managing plaque psoriasis. These medications are applied directly to the skin and include corticosteroids, vitamin D analogues, retinoids, calcineurin inhibitors, and salicylic acid. Corticosteroids help reduce inflammation and relieve itching, while vitamin D analogues slow the growth of skin cells. Retinoids, which are derived from vitamin A, can help normalize DNA activity in skin cells. Calcineurin inhibitors reduce inflammation and plaque buildup, and salicylic acid helps remove scales. These treatments can be very effective for mild to moderate psoriasis. It’s important to use these medications as directed by a healthcare provider to avoid potential side effects and ensure the best results.

2Lifestyle and Home Remedies

In addition to medical treatments, lifestyle changes and home remedies can help manage plaque psoriasis. Keeping the skin moisturized is essential to reduce dryness and scaling. Using gentle, fragrance-free moisturizers and taking regular baths with Epsom salts or oatmeal can soothe the skin. Avoiding triggers such as stress, smoking, and excessive alcohol consumption is also important. A healthy diet rich in fruits, vegetables, and whole grains can support overall health and potentially reduce flare-ups. Regular exercise and maintaining a healthy weight can improve symptoms and reduce the risk of associated conditions like heart disease and diabetes. It’s also beneficial to join a support group or seek counseling to cope with the emotional aspects of living with a chronic condition like psoriasis.

3Systemic Medications
0 votes
For moderate to severe plaque psoriasis that does not respond to topical treatments or phototherapy, systemic medications may be prescribed. These medications work throughout the body and include biologics, oral retinoids, methotrexate, cyclosporine, and newer oral treatments like apremilast. Biologics are a newer class of drugs that target specific parts of the immune system and are administered by injection or infusion. Oral retinoids can help reduce skin cell production, while methotrexate and cyclosporine suppress the immune system to reduce inflammation and slow down the overproduction of skin cells. Apremilast works by reducing inflammation through a different pathway. Systemic medications can be very effective but may have significant side effects, so they require careful monitoring by a healthcare provider.

Phototherapy, or light therapy, is a common treatment for moderate to severe plaque psoriasis. This treatment involves exposing the skin to ultraviolet (UV) light under medical supervision. The most common types of phototherapy include UVB phototherapy, narrowband UVB therapy, and PUVA (psoralen plus UVA). UVB phototherapy involves exposing the skin to UVB light, which slows the growth of affected skin cells. Narrowband UVB therapy uses a specific wavelength of UVB light that is more effective and requires fewer treatments. PUVA combines UVA light with a photosensitizing medication called psoralen to increase the skin’s sensitivity to the light. Phototherapy can be very effective in reducing symptoms and achieving long-term remission, but it requires consistent treatment sessions and can have side effects such as skin aging and an increased risk of skin cancer.

5What Plaque Psoriasis Looks Like

Plaque psoriasis typically appears as raised, red patches covered with a silvery white buildup of dead skin cells, known as scales. These patches, or plaques, can occur anywhere on the body but are most commonly found on the elbows, knees, lower back, and scalp. The affected skin is often dry, cracked, and may bleed. Plaque psoriasis can vary in severity from a few spots of dandruff-like scaling to major eruptions that cover large areas. The condition can also cause nail changes, including pitting, abnormal nail growth, and discoloration. Some people experience joint pain and swelling, a condition known as psoriatic arthritis. It’s important to consult with a healthcare provider for an accurate diagnosis and to determine the best course of treatment.
