Key Information:

  • The Root Cause: Psoriasis isn’t just a skin problem; it starts with your immune system.
    • The Security Team Analogy: Think of your immune system as a “security team.” In psoriasis, this team becomes over-protective and sends out incorrect signals.
    • Genetics: This is often linked to genes you inherit. It is not caused by poor hygiene or anything you have done.
  • The Pile-Up:
    • Normal Skin: Cells replace themselves over 3 to 4 weeks.
    • Psoriasis: The “security team” tells cells to grow too fast, in just a few days.
    • The Result: This rapid growth causes a “pile-up” of new cells on the surface, creating the plaques you see.

Important Facts

  • Not Contagious: Psoriasis is not an infection. You cannot catch it, and you cannot pass it on to anyone.
  • Manageable: While there is no cure yet, there are many safe and effective treatments to manage the symptoms.

When to Seek Advice Sooner

Psoriasis is a long-term condition, but you should contact us sooner rather than later if you experience:

  • Skin that becomes very painful.
  • Swollen or stiff joints (this can be related to the condition).
  • Signs of infection, such as weeping fluid or increasing redness/heat.
