The risk is most obvious with leave-on products, but rinse-off products can still transfer if residue remains on hands, hairline areas, towels, or pillowcases."]},{"heading":"Causes","paragraphs":["The bleaching comes from contact between benzoyl peroxide and dyed material or hair. Towels, pillowcases, collars, washcloths, and dark shirts are common places users notice the problem."]},{"heading":"Seriousness","paragraphs":["This is a cosmetic and household-care issue, not a medical emergency. It can still be frustrating because the color loss may be permanent on fabric."]},{"heading":"When to Seek Care","paragraphs":["Clinician care is not usually needed for fabric bleaching alone. Seek care if the skin itself becomes painful, swollen, blistered, severely irritated, or does not improve after stopping the irritating product."]}]}
