What is Psoriasis?
Psoriasis is an inflammation in the skin that is driven by the body’s own immune system. The inflammation in the skin causes the skin and creates red, itchy, and scaly lesions mainly around the elbows, knees and scalp. The chronic condition can appear as early as childhood. While it’s not contagious, psoriasis is a condition that is important to seek the help of a dermatologist.
What Are the Symptoms of Psoriasis?
Inverse Psoriasis
Inverse psoriasis appears in the armpits, groin, genital area, behind the knees, or underneath the breasts. Affected areas are moist, shiny, smooth and often an irritated red color. Hard to diagnose, inverse psoriasis can look like allergic reaction or a fungal infection.
Plaque Psoriasis
The most common type of psoriasis causes red, raised patches of skin, often covered with a white, plaque-like scale. These patches appear primarily on the knees, elbows, and scalp.
Guttate Psoriasis
Often appearing on the legs, arms, torso, face and scalp, guttate psoriasis consists of small red, scaly, teardrop spots that appear suddenly.
Pustular Psoriasis
Symptoms of pustular psoriasis are small pustules — blisters containing pus — in specific areas of the body or widespread throughout. This is a severe type of psoriasis and often appears quickly and in cycles.
Erythrodermic Psoriasis
The most severe and rarest form of psoriasis, erythrodermic creates fiery red skin that sheds in large pieces. This type of psoriasis destabilizes body temperature and can be life-threatening. If you believe you have erythrodermic psoriasis, seek medical attention immediately.
What Causes Psoriasis?
Caused by an overreaction of the immune system, psoriasis is a disease in which the body has been tricked into thinking an infection exists in the skin. A combination of genetic and environmental factors, the specific triggers of psoriasis vary for every individual.
When the immune system tries to treat the infection with the acceleration of skin cells, itchy plaques or other marks appear on the skin. While it may not be an aesthetically pleasing experience, psoriasis isn’t contagious and can be managed.
There are genetic links to psoriasis, and while it’s not 100% hereditary, it does tend to run in families. Typically, it’s a combination of these factors that causes psoriasis to appear. If you get it, you’re likely genetically predisposed to psoriasis and experiencing a stressor (emotional, physical, mental, or food-related) that triggered a reaction.
What Are the Treatment Options for Psoriasis?
Topical Steroids
For psoriasis, topical steroids are a mainstay treatment. A topical steroid may be all you need to clear up your condition. Often topical steroids can be used with other topical or systemic therapies. Topical steroids can be used to treat small areas that other treatments are not clearing.
Oral & Injectable Medication
Oral and injectable medications are systemic treatments for psoriasis. These systemic medications are typically the most effective therapies for clearing psoriasis. Systemic medications are prescribed to treat moderate to severe psoriasis. When 3-5% of the body’s surface area is covered by psoriasis, dermatologists typically consider systemic medications.
Dermatologists have a large number of options to consider when selecting a systemic treatment. Oral medications tend to target the inflammation caused by the immune system. Injectable or biologic drugs target the pathways that the body’s immune system uses that lead to inflammation. Biologic drugs selectively suppress the immune system in a very specific way to block the inflammation that leads to psoriasis. Most patients do not have problems of more colds but they do have more risk of certain health problems and need to be followed by their dermatologist every six months. These medications are very helpful for managing psoriasis, many patients can be completely clear of their plaques.
FAQs About Psoriasis
Is psoriasis contagious?
No. you cannot contract or spread it through physical contact.
My psoriasis improves after I’ve been in the sun. Can I use a tanning bed for treatment?
Before we understood the causes of skin cancer, doctors exposed patients to UV light to treat their psoriasis. Symptoms improved as the light calmed the immune system. However, we have more effective treatments and can avoid exposing patients to harmful UV rays.
Is there a difference between eczema and psoriasis?
Even though both conditions appear as red, scaly patches, eczema and psoriasis are not the same. Eczema can be found in the folds of the skin, like behind the knees and elbows, while psoriasis appears on the outside of those same areas.
Eczema patches have exaggerated skin lines, and the scales are thin with possible blisters. Cracking and weeping of the skin are more common in these areas.
Psoriasis, on the other hand, appears as well-defined plaques. The scales are thicker, stacked on top of each other, and turn extremely red. Occasionally, they’ll crack and bleed.
Can psoriasis be cured?
Research is constantly advancing around treatment for psoriasis, but currently, there is no known cure. However, with the assistance of your dermatologist, steroidal, non-steroidal and oral medication, psoriasis can be managed.
Do I Have Psoriasis or Seborrheic Dermatitis?
It’s easy to confuse these two scalp conditions. Sometimes they overlap, and they’re often treated similarly. But the causes and severity of the conditions differ.
Seborrheic dermatitis flares up because of a yeast that lives on the oils in the skin. The yeast causes mild irritation, redness, flaking, and itching. Usually, it occurs at the back of the scalp. (If it’s all over the scalp, it’s dandruff.) Other times, seborrheic dermatitis shows up as red, scaly areas in the eyebrows, around the nose, in the ear, or behind the ears.
Seborrheic dermatitis responds well to treatment and heals temporarily. But the yeast never goes away completely, and the oil your skin produces is unchangeable. So when it eventually comes back, you have to treat it again.
Psoriasis is more severe. You’ll notice similar, yet more intense, symptoms such as red, irritated, dry, flaky, itching skin.
Since no one treatment is effective for everyone, find a dermatologist that will work to find the best solution to your psoriasis symptoms. Whether it’s a pill or topical medication, there’s a treatment that will work for you.
