What published research says
These numbers come from outside sources, not our directory; each one links to its source below.
- FDA's public FAERS data (openFDA, through the 2026-07-30 update) contain 34,107 adverse-event reports listing cyanocobalamin (vitamin B12) as a suspect drug; these are voluntary report counts across all forms and uses, not rates. [2]
What these numbers can't tell you
- Counts are Google Maps listings we classify as med spas, so they include dermatology and plastic surgery practices that offer med spa treatments and exclude spas without a Google listing.
- A treatment counts when the spa's Google listing or website names it, so a spa with an outdated menu can be over- or under-counted.
- Credentials count only clinicians a spa names with a credential (MD, DO, NP, PA, RN) on its own website, so spas that leave their team off their website are left out of those shares.
- We hold no patient records: every figure describes providers, their listings and their Google reviews, not who gets treated.
- Ratings and review themes are Google's, as shown on each listing on the snapshot date; Google filters some reviews and does not publish how.
