Injuries to the Skin
Asides from the causes as mentioned above, trauma to the skin can also cause psoriasis, although this will only happen at the site of the injury. Injuries like cuts, scrapes, bruises, burns, bumps, vaccinations, tattoos and other skin conditions can cause the symptoms of psoriasis to flare up. Before you know it, the site of the injury is developing a dry and flaky surface, and as the skins are replaced more quickly than usual, psoriasis occurs. [8]
