Psoriasis is a chronic skin disorder that is marked by patches of intensely itchy and flaky skin that doesn’t go away with regular moisturizers the way most ordinary dry skin will. It can affect any part of the body, even the scalp and nails, and can be mild, moderate or severe. Most medical experts agree that it is a genetic condition, though a number of environmental factors — stress and physical injury chief among them — can cause flare-ups. People who suffer from the condition are often very self-conscious about it, particularly when skin aberrations occur on the face, hands, or other highly visible parts of the body. It is not contagious and can’t be transmitted to others, but it often looks unsightly and is usually very uncomfortable, too. Certain medicated creams and other lifestyle choices can help reduce the appearance and severity of the condition, but there isn’t usually any way to completely cure it.

Basic Symptoms

Skin itchiness and general discomfort are the two things people most commonly associate with the disease, and it often starts out as no more than brief rashes over certain parts of the body that look like little more than dry skin. As the condition worsens, though, those dry patches tend to get increasingly red and to grow; ultimately, the surface of the skin will dry out and form rough scales that often have a blistered look. Sometimes they flake off, either on their own or as a result of itching. The condition often covers large swaths of the body, and can move around, too.

Main Types

There are usually five recognized types of the disorder, each with its own intensity and symptom specifications. Plaque psoriasis causes red, silvery-white, scaly skin lesions, and this is the most common variety. The condition can also come in pustular form, which causes blisters to erupt on the skin that can leak pus or other fluids. This variation is most common on the hands and feet.

Erythrodermic versions of the condition lead to severe redness and shedding of the body surface, and the skin becomes excessively flaky, often coming off in large patches. In its guttate form, the disease appears as red, drop-like dots on the skin and a condition known as “inverse psoriasis” causes smooth, inflamed lesions in body creases, most commonly elbows, knees, and underarms.

Triggers and Causes

The condition is caused by genes, and is usually recognized by those in the medical profession as an inherited genetic disorder. Not everyone who carries the genes for the disorder will necessarily suffer from it, though, which is where environment begins to play a very big role.

Climate and weather, cold and dry temperatures in particular, can trigger the disease in many people. Physical trauma can also be to blame. Psoriatic lesions often develop at the site of a skin injury, usually right where things are healing and the skin is trying to regenerate itself. In a similar vein, infections can also be causes, either internal like respiratory conditions or external like infected cuts or blisters.

Most practitioners also think that stress and emotional health play a role in symptom suppression and flare-ups. People who are under a great deal of stress often see the condition appear for the first time, or worsen if it is already present. Certain pharmaceutical drugs, particularly those containing lithium, can also make the condition worse for many people.

Treatment Options

There isn’t usually any way to completely cure the condition, insofar as it is not medically possible to re-code peoples’ genetic predispositions. Certain medications and treatment regimens can help keep flare-ups suppressed, though, and can dramatically alter patients’ quality of and enjoyment of life. Skincare experts usually start by looking for ways to reduce triggers. Medicated creams and ointments are commonly prescribed, and in some cases UV light therapy, also known as “phototherapy,” can be useful, particularly for people who live in relatively dark and cold climates or who spend most of their days indoors away from natural sunlight. A number or oral medications can be prescribed to try to treat the condition internally, though these often have a number of side effects and are typically only used in extreme cases.

Psoriasis on the face can be devastating for people, but there are some things you can do to help promote healing. Putting cashew nut oil on the damaged skin after a good washing can help calm the skin and make it look healthier. Also, making a facemask out of cabbage leaves, minus the thick veins, has been proven to be an effective home remedy.

If you don’t have cabbage to make a mask, trying a mud mask can work as well, as the mud can pull out impurities from the skin improving its condition.

Finally sunlight has been known to help the skin recover from psoriasis in safe doses. Don’t allow yourself to get burned though, or you can make things worse.

Does anyone else have any good tips on how to treat psoriasis?

If you have psoriasis it can be very embarrassing, and people will often do everything they can to cover the areas displaying symptoms.

For many, their arms have red scaly lesions, which they feel is unattractive and will cause people to avoid them, so they wear long sleeves.

There are some things you can do to help the condition. Never scratching, and wearing natural fabrics can help your skin. Also, if you suspect your skin gets worse when you eat certain food, you may need to cut back or eliminate it all together.

Some believe that taking high doses of Vitamin E can help with the appearance of psoriasis, lessoning the severity of lesions.

The outside layer of regular skin is replaced every thirty days. In case of psoriasis it is replaced much faster, something like three to four days. The patches on the skin are dry, dead skin cells that keep accumulating.

Apparently sunbathing is effective in controlling psoriasis. Avoiding and controlling stress can help keep psoriasis in check too.
