The Device Malfunction Mid-Session
During a 30-minute radiofrequency facial on a 58-year-old client, the handpiece suddenly delivers an intense heat spike to the left cheek. The client flinches and reports sharp pain. On inspection there is a 1.5 cm area of marked erythema with a small raised wheal but no blister or broken skin. The device display shows no error code and the treatment has run for 18 minutes at settings used previously on this client without incident. The clinic's only other practitioner is with a client. The device was serviced seven months ago and the logbook shows no faults. The client is shaken, asking whether she will be scarred, and wants to continue so she does not waste the session.
1. Set out your immediate clinical and equipment actions in priority order, with reasoning.

Priority one is stopping and cooling. Terminate the treatment, remove the handpiece from the skin and switch the device off at the mains so it cannot be reactivated accidentally. Assess the injury: 1.5 cm of marked erythema with a wheal and intact skin suggests a superficial thermal injury without epidermal loss, which is reassuring but still requires cooling. Apply cool, not icy, compresses for 10 to 15 minutes, avoiding direct ice contact, and keep the area clean and dry. Do not apply actives, acids, retinoids or occlusive balms. Photograph the area with consent and a scale reference, and record the time, settings, duration, anatomical site and the client's reported sensation.
Priority two is the client. Reassure her calmly, explain what you see and what you are doing, and answer the scarring question honestly: with intact skin and prompt cooling, scarring is unlikely, but pigmentation change is possible and will be reviewed. Do not promise a perfect outcome.
Priority three is the device. Quarantine it: label it out of service, remove it from the treatment room and record the incident in the device logbook with time, settings, fault description and your name. Do not attempt another treatment on it, and do not let a colleague use it before inspection. Report to the device supplier or service agent for investigation, and check whether the fault is notifiable to the relevant regulator or insurer under your jurisdiction's rules. Complete an incident report the same day.
2. The client asks to continue the session. How do you respond, and what follow-up and documentation plan do you put in place?

I decline to continue, and I explain why in terms she can accept: the skin has just received an uncontrolled thermal dose, and further energy over or near that area would compound injury and make the outcome harder to predict. Continuing would not recover value from the session; it would risk converting a minor injury into a significant one. I offer to credit the unused portion of the session to a future appointment once the skin has settled and the device has been cleared, so she is not financially disadvantaged.
Follow-up: give written aftercare instructions (cool compresses as needed, gentle cleanser, bland moisturiser, daily SPF 50, no heat, exercise, alcohol, exfoliation or actives for at least 72 hours), and warn her to contact the clinic or seek medical review if blistering, increasing pain, spreading redness, fever or open skin develops. Arrange a review in 48 to 72 hours, in person or by photograph, and a further review at two weeks to assess pigmentation. Provide the clinic's contact details and out-of-hours guidance.
Documentation: an incident report covering the timeline, device settings, injury description, photographs, first aid given, advice provided, the client's decisions, the device quarantine and the referral for inspection; a clinical note in the client record; and notification to the clinic owner and insurer as required. If the injury worsens or the client requests it, support referral to a medical practitioner. I also review whether my own technique or the treatment parameters contributed, without defensiveness, as part of the incident review.
