Ischemia after nasolabial fold filler
The exact dose of hyaluronidase, the route of administration, and the maximum time to infiltrate — everything must be available in seconds, not in Google searches.
Operational support for aesthetic medicine
When a complication strikes, acting fast changes the outcome.
Operational support platform for healthcare professionals in aesthetic medicine. Protocols for complications and emergencies, with step-by-step guides, timers, flashcards, and quick access on your phone.
Evidence-based protocols
Critical time always visible
Always with you, always ready
Secure, private and reliable
The reality of the office
Complications don't warn. And they won't wait for you to recall the protocol.
Every aesthetic practice coexists with the risk of adverse events. The difference between outcomes lies in the speed and precision of the initial response.
Anaphylactic reaction during the procedure
Does your team know where the epinephrine is? Do they know the correct dose per kg, the IM route in the vastus lateralis, and the criteria for dose repetition?
Sudden visual loss after glabellar filler
The therapeutic window is under 90 minutes. What are the first steps? Where to refer? What documentation is mandatory?
Systemic local anesthetic toxicity
Prodromal signs, maximum dose calculation, Intralipid 20% bolus and infusion indication. No room for clinical improvisation.
