Psoriasis is a chronic inflammatory condition that affects the skin and, for some people, the joints. It can cause patches of skin that are thick, scaly, itchy, sore, or discolored. Although psoriasis can be frustrating and uncomfortable, a growing range of treatments can help control symptoms and improve quality of life.

Psoriasis is an immune-mediated disease. In psoriasis, an overactive immune response speeds up the normal cycle of skin-cell growth. Instead of shedding gradually, skin cells accumulate on the surface, creating the characteristic plaques and scales associated with the condition.

Psoriasis is not contagious. You cannot catch it by touching someone who has it, sharing clothing or towels, swimming in the same pool, or having close physical contact.

What Does Psoriasis Look Like?

Psoriasis can appear differently depending on the type of psoriasis and a person’s skin tone. Common symptoms include:

  • Raised or thickened patches of skin
  • Silvery-white, gray, or otherwise noticeable scaling
  • Itching, burning, tenderness, or soreness
  • Dry skin that may crack or bleed
  • Changes to the fingernails or toenails, including pitting, discoloration, thickening, or separation from the nail bed
  • Symptoms that improve for a period and then flare again

Commonly affected areas include the scalp, elbows, knees, lower back, hands, feet, and nails, although psoriasis can occur almost anywhere on the body.

What Causes Psoriasis?

There is no single cause of psoriasis. Genetics and the immune system both play important roles, and environmental factors can influence when symptoms appear.

Certain factors may trigger or worsen a flare in some people. These can include stress, skin injuries, infections, smoking, alcohol, weather changes, and certain medications. Triggers vary considerably from person to person, so identifying individual patterns can be useful when managing the condition.

Different Types of Psoriasis

Plaque psoriasis is the most common form and typically produces well-defined areas of inflamed, scaly skin.

Guttate psoriasis often causes numerous small, drop-shaped spots and can sometimes develop following an infection.

Inverse psoriasis affects skin folds, such as the armpits, groin, or underneath the breasts. The affected areas may appear smooth and inflamed rather than heavily scaled.

Pustular psoriasis causes pus-filled bumps surrounded by inflamed skin. Some forms can be serious and require prompt medical care.

Erythrodermic psoriasis is a rare, severe form that can affect a large portion of the body. It can be a medical emergency and requires immediate medical attention.

Psoriasis and the Joints

Psoriasis isn’t always limited to the skin. Some people develop psoriatic arthritis, which can cause joint pain, stiffness, swelling, and reduced mobility.

People with psoriasis who experience persistent joint symptoms should discuss them with a healthcare professional. Identifying psoriatic arthritis early is important because treatment can help reduce inflammation and protect the joints from damage.

How Is Psoriasis Treated?

Treatment depends on the type, location, and severity of psoriasis, as well as a person’s overall health and response to previous treatments.

Options may include topical treatments, such as corticosteroids and vitamin D-related medicines; phototherapy, which uses controlled ultraviolet light; oral or injected systemic medicines that affect inflammation throughout the body; and biologic medications, which target specific parts of the immune system involved in psoriasis.

A dermatologist can help determine which treatment is appropriate. Because psoriasis is a long-term condition, treatment sometimes needs to be adjusted over time.

Everyday Strategies for Living With Psoriasis

Alongside medical treatment, everyday habits may help some people manage their symptoms. Regularly moisturizing the skin can help reduce dryness and irritation. Avoiding known personal triggers, managing stress, following a balanced lifestyle, and avoiding smoking may also be beneficial.

It is important to be cautious about products or diets promoted online as a “cure.” Psoriasis currently has no cure, and natural does not necessarily mean safe or effective. Supplements and complementary treatments can also interact with medications, so they should be discussed with a healthcare professional.

When Should You See a Doctor?

Consider speaking with a healthcare professional if you develop persistent or unexplained skin changes, psoriasis is interfering with sleep or daily activities, symptoms are getting worse despite treatment, or you develop joint pain, swelling, or stiffness.

Seek urgent medical attention for severe symptoms affecting a large area of the body, particularly when accompanied by fever, chills, dehydration, or feeling seriously unwell.

The Bottom Line

Psoriasis is more than a cosmetic skin problem. It is a chronic immune-mediated condition that can affect physical comfort, confidence, daily activities, and, in some cases, joint health.

The good news is that treatment options have advanced significantly. With an accurate diagnosis, an individualized treatment plan, and ongoing care, many people with psoriasis can achieve substantial improvement and long periods of clearer skin.
