The Claim

Vitiligo is sustained by a failure of immune resolution and impaired tissue regeneration, characterized by persistent melanocyte-specific tissue-resident memory T cells (TRM) maintained by IL-15 trans-presentation from keratinocytes, leading to chronic inflammation and inability to restore cutaneous homeostasis despite clinical stability.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Vitiligo persists due to ongoing immune activity targeting skin pigment cells, driven by signaling molecules from skin cells that maintain destructive immune cells in the skin, preventing restoration of normal skin tissue balance.

Why this might work

Skin color cells get damaged by too much chemical stress, which makes them look dangerous to the immune system. This triggers immune cells to attack and kill the color cells. The immune system then remembers these cells as targets and keeps sending killer cells back to the skin, even after the damage stops. These killer cells are kept alive and active by signals from skin cells, which also call in more killer cells to the area. The skin cannot repair itself because the immune system keeps destroying any new color cells that try to grow back.

  1. Study: Vitiligo as a Failure of Immune Resolution and Tissue Regeneration: From Stress Signals to Targeted Immune Modulation

    This study says vitiligo doesn't go away because the body's immune system keeps attacking skin color cells, even when it should stop, and the skin can't repair itself — like a broken alarm that won't turn off and a wall that won't heal.
