Common question

Why does a vitiligo patch turn red?

A depigmented patch can redden quickly in the sun. Friction, a product, local treatment, inflammation or infection may also be responsible.

In brief

Key points

  • Sunburn is common
  • Consider irritation
  • Cool and protect
  • Seek help for blisters or severe pain
01

Consider the context

Recent UV exposure, a new product, rubbing, heat or prescribed treatment provide clues. Blisters, swelling, fever or rapid spread need prompt advice.

02

Prevent another burn

Move into shade, cool the area gently and avoid further exposure until recovered. Combine broad-spectrum sunscreen with clothing and shade.
