Can I say it?
Can I say “guaranteed results” in a med spa ad?

The short answer
It depends. The checker warns on this wording but does not block it. The first rule it hits is CG-ABS-001. Its reason: Outcome guarantees are unsubstantiated absolute claims.
Source the rule cites: FTC Act section 5, 15 U.S.C. 45; FTC Health Products Compliance Guidance
