Why does the Koebner phenomenon happen?

ANSWER

  • Doctors aren’t exactly sure what makes your skin respond to an injury with plaques. You can have a Koebner response from anything that changes your skin on the outside or the inside, including: Injuries such as animal bites, stings, burns, cuts, bumps, or rubbed skin
  • Conditions like diaper rash, eczema, infection, scabies, warts, or dermatitis
  • Allergic reactions or skin irritations
  • Sunburn or radiation You can also trigger the condition when you get a tattoo, vaccinations, or acupuncture. Even everyday activities like shaving can cause a flare-up. The weather also plays a role; the Koebner phenomenon happens more often during cold winter months and less often in warm summer months.
