What is psoriasis?

Psoriasis is a chronic disease that usually causes excessive skin peeling and pruritus. It is characterized by periods of skin scale severity and remission.

Psoriasis is NOT contagious! It cannot be spread from person to person.

Psoriasis can take different stages of severity, depending on the person.

Skin lesions forms red lumps, clearly separated from the healthy skin, and creating crusty patches. They normally appear on elbows, knees, lower back and scalp, but they can also appear anywhere on your body.

The exact causes of psoriasis are not fully understood. Research shows that genetic factors play an important role, however, external issues (environmental, dietary, stress-related) are also significant.

Psoriasis can start at any age but mostly develops during puberty and in the 50s. Men and women are affected with equal frequency.

Psoriasis affects around 2% of people in the UK – so do not be afraid – you are not alone!

Why does psoriasis appear?

1. Healthy skin

Healthy skin is a strong, tight and elastic barrier which provides the proper protection against external factors. What is more, it is a protection against the excessive water loss and penetration of allergens. It is built of symmetrically arranged layers of cells and a cementing substance that connects them.

2. Skin affected by psoriasis

In people with psoriasis, the skin structure is damaged. This is accompanied by the excessive thickening of the outermost layer – stratum corneum. There is a harmony in person with no skin diseases between the process of multiplication and exfoliation of the epidermis. Skin with psoriasis is red, dry and covered with the excessively peeling epidermis, which grows in layers and creates a scaly outer layer.

What are the symptoms of psoriasis?

  • Red, flaky, crusty patches of skin covered with silvery scales,
  • Itching in the area where lesions occur,
  • Skin lesions can be painful (especially after scratching them),
  • In mild cases, the skin is only dry, red and flaky,
  • In more severe conditions the skin may break, scratching impairs the healing process and increases the risk of infections,
  • Excessive scratching causes more pruritus, creating a vicious circle (pruritus – scratching – pruritus).

Where are the skin lesions located?

Skin lesions mostly appear on:

  • elbows,
  • knees,
  • scalp,
  • face,
  • hands,
  • lower back,
  • fingernails and toenails,
  • the genital area.

How to avoid factors that worsen the symptoms of psoriasis?

To avoid factors that can cause irritation, you have to be aware of its main causes. These could be perfumed soaps, some cosmetics or perfumes, detergents, or even wearing itchy fabrics like wool. Other factors triggering psoriasis lesions are intensive stress and scratching abnormal skin patches.

You can avoid it by replacing traditional soap with gentle cleansing emulsion, not using perfumed cosmetics, wearing light clothes made of soft fabrics, and using suitable topical treatments recommended for people suffering from psoriasis.

How to support psoriasis therapy?

It is important in psoriasis to make a habit of moisturising the skin at least twice a day. Do not stop this routine during remission – that means when your lesions are healed.

The fundamental rule in psoriasis therapy is moisturising and replenishing the skin systematically by everyday care routine with the right products. The special formula of non-irritant Mediderm products makes it safe and skin-friendly for people suffering from psoriasis. Mediderm was developed to improve the quality of our patients’ lives.

Mediderm products should be applied while bathing (Mediderm BATH OIL) or while showering (Mediderm BODY WASH), and immediately after washing the body – on dried skin (Mediderm CREAM). It will allow reducing irritations caused by detergents or soap.
