What is the Koebner phenomenon?

ANSWER

For some people with psoriasis, even the littlest pinprick or a bite from a mosquito can trigger plaques to appear in new places. Anytime your skin is hurt or irritated, you can get a new patch of psoriasis.

Doctors call this reaction the Koebner phenomenon, and it happens to 1 out of 4 people who have psoriasis.
