Wrinkle alert is an app that uses the 3D scan technology in an apple IPhone to measure the activity of the facial muscles precisely and consistently. By measuring specific zones in the face before and after Botulinum Toxin treatment we can compare the respective muscle activity and thus quantify the effect of the treatment. The app can be used to objectively measure the effect of different toxins and different doses at specific moments in a timeframe. The app is thus very useful for scientific and comparative studies. The app can also be used by patients to tell them the status of their botulinum toxin treatment and inform them when to go back to their practitioner. The user can send his data for analysis. The practitioner can provide a personalized wrinkle alert app license to their patients. In this way wrinkle alert is an ideal tool to recruit, inspire and keep your patient loyal to the practice.
