Psoriasis is a disease of the skin that causes thick, itchy patches of red skin and silvery scaling. According to, this disease impacts just over 3% of adults in America, or over 7.5 million. But why does it occur in the first place? In this blog, we’ll discuss everything you need to know about psoriasis including causes, treatment, and more.

Psoriasis skin disease

The top two layers of the skin are called the epidermis and dermis. Typically, new cells at the bottom of the epidermis are consistently moving up and replacing the older cells above them over the span of one month. In psoriasis, however, the cells reach the skin surface in just six to eight days. This happens most often as a result of a poor immune system. However, it is also highly common in fair skin people and adults.

How Does Psoriasis Occur?

It is the common belief of scientists that the immune systems of those with psoriasis mistake different natural substances in the skin for foreign invaders. As a result, the immune system performs a counterattack also known as the body’s natural inflammatory response. When this occurs, a series of changes take place within the body, including enlarged and increased amounts of blood cells, an increase of immune cells in the area, and faster new skin cell production. Ultimately, this becomes a cycle that leads to thicker skin with raised, itchy and inflamed patches known as plaque.

In terms of its origins, Healthline explains that while people with no family history of psoriasis can get the disease, having a family member that has the disease does increase your chances. This is the case because the disease can be passed through parts of your DNA. If you’ve recently discovered that you have psoriasis, there are some triggers to consider avoiding, such as:

  • Skin injuries like bug bites, etc.
  • Dry skin or weather
  • Stress
  • Infections, such as skin or strep infections
  • Smoking
  • Certain medications
  • Alcohol

Types of Psoriasis

Psoriasis skin disease

Much like various other skin conditions, there are several different types of psoriasis, each with its own symptoms. Continue reading below to learn more about the various types of psoriasis.

Plaque Psoriasis

Plaque psoriasis is the most common form of this disease. It appears in the form of red, raised patches with a silvery-white buildup of dead skin cells that are often itchy and/or painful. More often than not, it shows up on the scalp, elbows, lower back, and knees. If the patches are allowed to dry to a point of cracking, they can bleed.

Guttate Psoriasis

Guttate psoriasis appears as small dot-like lesions. It is often seen in children and young adults. In addition to the triggers mentioned above, guttate psoriasis is also triggered by strep infections. In all, around 10% of psoriasis-affected people have guttate psoriasis, specifically.

Inverse Psoriasis

Inverse psoriasis appears in the form of red lesions found within the folds of the body. This usually means under the arm, behind the knees, or in the groin. On rare occasions, inverse psoriasis appears smooth and shiny.

Pustular Psoriasis

Pustular psoriasis is characterized by white pustules or blisters filled with non-infectious pus. Furthermore, it is often surrounded by red skin and tends to show up on any part of the body. Most commonly, however, it presents on the hands and feet.

Erythrodermic Psoriasis

This is a severe form of psoriasis that results in an extensive fiery redness that spreads all over most of the body. Its most notable symptoms include cause severe itching and pain.
