The fraxel treatment tips do not delivery any energy and no treatment data is stored on the tip itself; there is no information to gather from their return.The exception to this would be if the fraxel tip plastic housing or component scratched the patient.For other reported events, tips are not a viable source of evaluation data.The system has no system/data logs that can be reviewed.The system has software safeguards (such as a power on self-test) that will trigger error/event codes should the system be outside of acceptable limits.The customer can also utilize the burn paper to confirm the system laser is providing correct pattern/coverage.The customer performed the burn paper test and review showed proper pattern/coverage.Product evaluation did not confirm the failure mode.The customer was advised to make certain that the hand piece, snout, lens, and tip are always cleaned prior to each use, and cleaned after each treatment as well.According to fraxel dual 1550/1927 laser system user manual, burns and blisters are known possible complication after fraxel treatment.Blistering or burns may develop over the treated areas.No non-conformities or anomalies found related to this complaint when reviewing the device history record.The lot history, trend analysis, risk analysis and directions for use review were considered acceptable, with the product performing within anticipated rates.This event is most likely unrelated to the device.Based off the available information, burns and blisters are known possible complication after fraxel treatment.No corrective action is necessary.
