Which skin conditions can be triggered by the Koebner phenomenon?
The Koebner phenomenon specifically refers to the development of new psoriasis lesions on previously unaffected skin after an injury or trauma. It occurs in about 25 percent of people with psoriasis and can trigger multiple types of psoriasis.
When your skin experiences damage from various sources, new scaly patches of psoriasis can appear in those exact spots. Common triggers include:
- Scratches and cuts
- Burns and sunburns
- Insect bites
- Tattoos
- Surgical scars
- Excessive scratching
- Irritants
- Pressure or friction (like from face masks or piercings)
- Hair removal (waxing, ingrown hairs)
A MyPsoriasisTeam member shared: "I get psoriasis wherever I cut myself. Ingrown hair, scrapes, or pimples all become new plaque psoriasis spots on me."
The phenomenon can appear in unusual places where you experience repeated pressure or injury. Once the initial wound heals, a new psoriasis patch typically develops in its place.
If you've noticed this pattern with your psoriasis, it's important to protect your skin from injury and discuss prevention strategies with your healthcare team.
