If you came looking for someone to ask, where to go depends on the question. Your health, a practitioner's license and a product-safety report need different kinds of help. This page points you toward those routes. There's no form here for sending personal information.
For a question about your own face
An appropriately licensed U.S. clinician can assess your personal situation. Take the proposed medicine or filler's name, its patient information and your questions. Ask how the proposal fits your medical history and what might make them advise against it.
You don't need to arrive with a decision. “I want to understand this” is a perfectly good reason for a conversation. The provider questions can help you prepare.
The toxin and filler chapters explain the different kinds of change. They can't decide which, if either, is right for you. You can ask for another explanation or another opinion.
For a concern after a procedure
After a botulinum toxin injection, trouble swallowing or breathing, double vision or muscle weakness need emergency medical help immediately. Don't wait for a website reply.
During or shortly after a filler procedure, unusual pain, vision changes or white, gray or blue skin near the treated area need immediate medical attention. Call 911 for breathing difficulty, and call 911 for suspected stroke, including sudden vision changes.
For other concerns after a procedure, contact the treating clinician promptly. This page can't tell you whether a symptom is harmless. More reading isn't a substitute for care.
For a licensing or product-safety concern
The state medical-board directory helps you find medical regulators. For a nurse or another profession, use that profession's state board. Keep the practitioner's full name and the concern clear in your notes.
FDA MedWatch is a route for reporting problems with medicines and medical devices. It doesn't arrange treatment or provide an emergency response. Get medical care first when you need it.
A licensing question and a product report aren't the same thing. Be clear about which issue you need help with when contacting a regulator.
For something you have read here
Open the linked source and check what it actually covers. Is it the same medicine or filler, use and age group you're asking about? The reference notes can help you find your way.
If the source leaves your personal question unanswered, take that question to a licensed clinician. General information can't give you a personal go-ahead.
