Does a med spa have to register or hold a license in New Hampshire?

Short answer
The cited rules do not settle this — no med spa-specific registration appears in them; they show only that estheticians (anyone practicing esthetics) and the shops they work in are licensed by the board of barbering, cosmetology, and esthetics.

New Hampshire defines the esthetician simply as any person practicing esthetics, and the definition of esthetics itself — an enumerated list of surface treatments — is set out in the supervision section of this reference. The PRICE of the credential sits in the Office of Professional Licensure and Certification’s fee rule: under Plc 1002.07 a barber, cosmetologist, esthetician, manicurist or master barber personal license is $55 for two years, an instructor license $82, a shop license $110 for two years, a school license $346 and a tanning facility registration $170, each covering initial issuance, renewal or reinstatement. These claims do not address med-spa or medical facility registration. On compounded drugs the Board of Pharmacy’s sterile-compounding rule answers the GLP-1 question three ways: a compounder shall not compound a sterile product of an FDA-approved product when the product is commercially available, and may use bulk ingredients only where no commercial source exists, such as an FDA backorder listing; a compounder preparing more than 50 dosage units of NON-PATIENT-SPECIFIC preparations must be registered with the FDA as a manufacturer or 503B facility, and one supplying fewer than 50 units to a provider for administration must hold a memorandum of understanding for each product and hand the practitioner the lot’s test results; and “compounding” itself includes anticipatory preparation on regularly observed prescribing patterns and preparation on a practitioner’s order that may be sold to the practitioner for office administration to a SPECIFIC patient, in limited quantities, not for resale.
