Serious cosmetic reaction: what should a UK buyer do?
Ask the user to stop using the cosmetic and seek medical help, alert the Responsible Person, preserve product and medical evidence, and assess affected stock. Report a serious undesirable effect to OPSS without delay while investigating. Factory records can be gathered by the China-based staff of Cambridge China Bridge.
Protect the user and recognise a serious case
Ask the affected person to stop using the product and seek appropriate medical help. If there appears to be an immediate threat to life, direct them to emergency care. Do not ask them to try the cosmetic again to prove the reaction. Record when your business first heard about the incident and appoint someone to coordinate the response.
For Great Britain, official guidance treats reactions causing temporary or permanent inability to carry out usual daily tasks as serious undesirable effects. Other examples include disability, hospitalisation, congenital abnormalities, risk to life and death. Assess the outcome, not simply whether the complaint says allergy or irritation. This guide covers England, Scotland and Wales.
Bring in the Responsible Person immediately
Send the incident details to the Responsible Person named on the packaging and involve the cosmetic safety assessor. Confirm who will submit the report and who will provide updates. Official guidance requires the Responsible Person or distributor to report serious undesirable effects without delay. Passing a complaint to the Chinese factory is not a substitute for arranging that report.
Check your role against the existing cosmetics sourcing guide, which explains the Responsible Person and pre-sale safety file. Keep supplier reimbursement discussions separate from user protection. Alert your insurer using your policy's reporting arrangements; our importer liability guide explains why factory assurances do not resolve your exposure.
Preserve the product and medical account
Ask for photographs of the product, packaging, batch code and affected area where appropriate. Preserve the used container, remaining contents and an unopened sample from the same batch if available. Keep samples labelled and separate from saleable stock. Record purchase details, use dates, application method, symptoms, onset, duration and outcome. Distinguish the person's account from a clinician's findings.
Ask what treatment was received and whether there was hospital admission or disruption to daily activities. With the person's agreement, obtain relevant medical documents through an agreed secure route. Record other products used alongside the cosmetic and relevant history without diagnosing the cause. Limit access to sensitive records and give the factory a case summary rather than circulating identifiable medical files.
Complete and submit the OPSS report
Check the official cosmetic serious undesirable effect reporting page listed in Sources and confirm with OPSS which form is appropriate for Responsible Persons and distributors. Official guidance asks for the Responsible Person's details, all serious effects experienced, the cosmetic's name and batch number, and corrective measures taken. Submit the completed form to the reporting email address given on that page.
As a practical approach, prepare a dated chronology and distinguish confirmed facts, reported information and unknowns. Do not delay reporting while waiting for the factory to accept blame or finish testing. Ask OPSS how to supply outstanding information and subsequent updates. Keep the submitted form, attachments, sending record and correspondence together. Local Trading Standards or your primary authority can help with the form.

Assess corrective action and control the restart
As an initial precaution, hold suspect stock while the Responsible Person and safety assessor examine the risk and batch scope. A report alone does not establish the cause or determine the recall boundary. Official guidance requires the Responsible Person to take appropriate corrective action, withdrawal or recall where there is reason to believe the cosmetic is non-compliant. A product presenting a human-health risk also requires immediate notification to, and cooperation with, competent authorities.
Ask the China factory for the actual batch formula, ingredient lots, production and release records, retained samples, test results and any process or packaging changes. Check related batches rather than assuming the complaint batch is the entire scope. Use the imported-product recall guide for customer notices and recovery. Feed adverse-effect information into the safety report and product information file; document the assessor's review, corrective evidence and restart decision.
Frequently asked questions
Does every cosmetic allergy need an OPSS report?
Assess the outcome. An allergy causing hospitalisation or inability to carry out usual daily tasks can be serious. Record other reactions too and ask the Responsible Person or safety assessor to review uncertain cases.
Can I wait for the Chinese factory's investigation?
Do not let the factory investigation delay a serious undesirable effect report. Report without delay, explain what remains unknown and ask OPSS how to provide further information.
What if the customer cannot find the batch code?
Preserve packaging photographs, purchase records and remaining product. Trace the sale through warehouse and shipment records. Mark the batch as unknown until supported by evidence.
Does a serious reaction automatically mean a recall?
Assess the risk and affected scope with the Responsible Person, safety assessor and relevant authority. Corrective action may involve withdrawal or recall. Keep suspect stock on hold while deciding.
