Psoriasis: Understanding Your Triggers

Psoriasis: Understanding Your Triggers

Psoriasis is a chronic inflammatory skin disorder that is initially activated by primary triggers1. Whilst the exact cause of psoriasis is unknown, the immune system and genetics are known to play a major role in its development2

The main types of primary triggers for psoriasis include:

  • Koebner Phenomenon– Injury or trauma to the skin i.e. burns, insect bites, surgical wounds, sunburn and tattoos.
  • Stress– anxiety, depression and other psychological illnesses (see the “Stress and Skin: Are They Connected?” blog.
  • Medications: Taking or cessation of certain medications such as beta blockers, lithium, non-steroidal anti-inflammatories and antimalarials.
  • Systemic infections – Including strep throat, tonsillitis, shingles and other viral/bacterial infections.


Once it has been activated, psoriasis can manifest in different forms, including:

  • Plaque (Chronic)
  • Guttate
  • Flexural (Inverse)
  • Psoriasis Annularis
  • Pustular
  • Palmo-Plantar
  • Erythrodermic EEC
  • Scalp
  • Nail
  • Psoriatic Arthritis

During a psoriasis flare, secondary triggers play a role in the continued exacerbation of the condition. In his research, Prof. Tirant discovered that such factors were often related to lifestyle, dietary and chemical exposure.

Management of triggers can play an important role in reducing the frequency and severity of psoriasis flare ups.  If you would like to learn more about how to manage your psoriasis triggers, please visit the Psoriasis Eczema Clinic at or contact the clinic for a personalized consultation 03) 9770 5337.
