What do the average citizen and Kim Kardashian have in common? If you’re one of the 7.5 million people in the United States who suffer from psoriasis, you and KK are in the same boat. She is one of an increasing number of celebrities who have spoken out about their battles with the skin disorder. Psoriasis affects millions of people worldwide, but the disease is still widely overlooked.

10. It’s more than a rash

Psoriasis causes itchy, flaky, red skin that looks like a rash, but it’s not just dry skin. It’s an autoimmune disorder in which the body is unable to distinguish between healthy cells and foreign bodies. Due to that, the body begins to attack its own organs and cells, which can be painful and difficult to deal with. This attack triggers an increase in the development of new skin cells in the case of psoriasis, resulting in dry, hardened patches on the skin’s surface.

9. Psoriasis is not something you can catch.

While psoriasis can appear infectious on others, don’t be afraid to shake hands or contact someone who has it. Even if a close relative eperiences psoriasis and you develop symptoms, it isn’t because you “caught” the disease from them. Since some genes have been related to psoriasis, having psoriasis-affected relatives increases the chances of developing it. The bottom line is that psoriasis is not infectious, so there is no risk of “catching” it.

8. Currently, there is no cure.

Psoriasis, like other autoimmune disorders, has no known cure. Psoriasis flare-ups can occur without warning, but there are many therapies that can reduce the number of flare-ups and bring about remission (a period of time when symptoms disappear). The disease may go into remission for weeks, months, or even years, depending on the person.

7. It affects even supermodels.

In addition to Kim Kardashian, celebrities like Art Garfunkel and LeAnn Rimes have publicly shared their psoriasis stories to aid others maintain a positive outlook. Cara Delevingne, a supermodel and actress, has been one of the most vocal, claiming that the modeling industry led to her having the disease. It eventually contributed to her public support for psoriasis.

Cara also acknowledged the common misunderstandings about the disease. People would put on gloves and refuse to touch me because they thought I had leprosy or something, she told The Times in London.

6. Triggers come in a variety of sizes and shapes.

A stressful career choice, whether modeling or anything else, may probably cause someone’s psoriasis to flare up, but it’s far from the only one. Other factors that may cause psoriasis flare-ups include skin injuries, infections, too much heat, smoking, and even alcohol consumption. For those living with the condition, it’s vital to recognize your triggers and take steps to protect your skin.

5. Psoriasis may affect any part of the body.

Psoriasis is an unpredictable condition that can affect any part of the body, but the head, hands, knees, elbows, and feet are the most popular sites. Facial psoriasis is possible, but it’s uncommon compared to other parts of the body. When the disease affects the face, it usually manifests itself along the hairline, brows, and the skin  area between the nose and the upper lip.

4. In the winter, symptoms can worsen.

Cold weather may also cause skin to become dry and inflamed. But here’s where things get complicated: in order to protect themselves from the cold, many people spend most of the time in their house during the winter months, which limits their sun exposure. Sunlight contains plenty of UVB and natural vitamin D, both of which have been shown to help avoid or alleviate psoriasis flare-ups. Each session should be limited to 10 minutes. Although the cold can be damaging to your skin, it’s always important to get some sun exposure.

3. Psoriasis usually occurs in your adult years

According to the National Psoriasis Foundation, the condition usually appears between the ages of 15 and 35, and both women and men are affected equally. About 10 to 15% of people with psoriasis are diagnosed before they reach the age of ten.

2. There are several types of psoriasis.

Plaque psoriasis is the most experienced type, characterized by elevated, red patches of dead skin cells. Other forms with distinct lesions include:

Furthermore, up to 30% of people with psoriasis may have psoriatic arthritis. Psoriasis of this kind causes arthritis symptoms such as joint inflammation and skin irritation.

1. The majority of people have mild cases.

Despite the fact that the severity of psoriasis varies from person to person, the good news is that 80% of people have a mild form of the disease, with only 20% having moderate to severe psoriasis. When psoriasis affects more than 5% of the body’s surface area, it is considered serious. If you think you’re having psoriasis symptoms, make an appointment with your doctor as soon as possible so they can assess your condition.
