Does my psoriasis make me more prone to skin infections? It may. Bacteria normally live on our skin, and research shows that the same types of bacteria found on healthy skin are also found on psoriasis lesions (although on lesions they appear in greater numbers). Normally, however, this does not cause infection. However, if an aggressive type of bacteria called Staphylococcus aureus is present, then the risk of developing a skin infection increases. If you think you may have an infection, consult your doctor.
Vigourous scratching resulting from itchy scaling can also increase the risk of infections. If you scratch too strongly, you risk injuring the skin which then opens the door to a bacterial infection. If you find you cannot avoid hard scratching, ask your doctor to suggest different options for itch relief.
