What causes psoriasis?
Psoriasis is an autoimmune condition, which means it is caused by an overactive immune system.2,7
This causes immune cells to constantly act as though they are fighting an infection or healing a wound.5,6 This leads to the abnormally rapid rate of skin cell multiplication, leading to these scales and patches.6
While the causes of psoriasis are unknown, there are a variety of triggers that can make it worse, including:
- Cold weather
If any of these triggers sound familiar to you, make sure you talk to your healthcare professional.
