Med spas in most states are required to have an MD or DO as the medical director. They collect a monthly fee and take responsibility for all the protocols. A lot of docs willing to do it just want the money and only agree on super conservative protocols that don't yield results.
There are a lot of hands in the medical cosmetics cookie jar from manufacturers to suppliers and providers. It's impossible to navigate without a lot of experience or a lot of expensive mistakes. Fortunately, my wife has a lot of experience and knew her stuff. Most don't.
Becoming an MD probably wasn't on your daughter's bingo card but it's the best way to do. At the very least, she needs to do nursing and get 4-5 years under her belt doing injectables and lasers on the side. She will have a much easier time navigating the BS and finding investors. To do it right a med Spa needs ~$1 million to start up. My wife did it with $500k but that was before horrendous inflation.
