Ultrasound is used in products ranging from surface cleaning to medical diagnosis and treatment. A beauty device cannot be classified merely because its name contains “ultrasound,” and use in a salon does not automatically exclude medical-device status.
1. Output facts to verify
- Nominal frequency and actual tolerance.
- Acoustic intensity, power or other measurable output.
- Continuous or pulsed operation, duty cycle and duration.
- Transducer area and focused or unfocused design.
- Coupling medium, contact pressure and movement.
- Levels, handpieces and software programs.
2. Body area and depth
Whether the energy acts mainly on the surface, shallow tissue or deeper structures affects risk and purpose. “Non-invasive” does not replace analysis of the actual acoustic field and biological interaction.
3. Intended purpose
Diagnosis, treatment, tissue repair, pain relief or deliberate physiological modification generally require medical-device analysis. A cleaning or daily-care purpose must still be supported by output and use that are consistent with that position.
4. Frequent inconsistencies
Examples include instructions saying “high-frequency vibration” while the technical file identifies an ultrasound transducer; marketing claiming deep infusion while the filing says surface cleaning; or several handpieces sharing one test despite different outputs.
5. Practical assessment sequence
- Confirm transducer and real output.
- Define contact, coupling and body area.
- Explain how cleaning, infusion or another purpose is achieved.
- Design output and safety verification.
- Align instructions, tests and marketing.
- Then determine classification or product redesign.
The status of an ultrasound beauty device must be assessed from its real parameters, body interaction and intended purpose, not its trade name.
