I have lived in both states and they both have very different laws. NC by far as much better sanitation like wearing gloves while waxing and not double dipping wax sticks (which is so gross!)and keeping an aseptic areas. Fl does not allow comedone extractors (NC does) and as far as I know eyelash tinting is legal in NC and illegal in Fl. Body wrapping in Fl is not something you can perform under an esthetician's license, you must go back and get a body wrap certificate. In terms of having your own spa in your home, if I remember correctly in Fl you can do that as long as there is a separate entrance/exit into the spa from outside, meaning the customers do not have to enter/exit through your home. There also has to be a bathroom in the spa, so the customer does not enter your home. Basically, the spa would have to be a separate entity from the house or you would have to have walls put up to separate your house from spa. There can be no direct access from the house into the spa without walking outside (please re-verify with state-but this was the way it was when I left FL).In Fl, as far as I am aware you use Microderm machines and electrical machines without a doctor's supervision. Back facials are legal in Fl as long as you do not massage, there is a fine line here, you can apply product in a relaxing way but you cannot call it massage. I think esthetics should be at the national level estheticians across the country know how to perform esthetics within the law.
