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

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.
