Vitiligo pattern over time: a 12-year observation

Many people ask a simple question:

“Does vitiligo follow a pattern?”

Most explanations focus on treatment or causes.
However, long-term observation suggests a different perspective.

Over a 12-year period, I documented how skin changes appeared over time.

Instead of random changes,
there were recurring patterns in how the condition progressed.

Some phases showed noticeable change,
while others remained stable for long periods.

This observation led to a structural framework called CS-NRRM™.

It is not a treatment model.

It describes how patterns appear and persist over time,
based on long-term observation.
