- AIt exfoliates the outer layer of dead skin cells through abrasion.
- BIt permanently removes hair follicles.
- CIt causes deep muscle contractions for toning.
- DIt produces a germicidal effect and increases circulation.
Show answer & explanationAnswer & explanation
Correct answer: D. It produces a germicidal effect and increases circulation.
High-frequency current, particularly through the generation of ozone, has a germicidal (antibacterial) effect and also stimulates blood circulation, making it beneficial for various skin conditions, especially acne-prone skin.
Why the other options are wrong
- A. Exfoliation through abrasion is achieved with microdermabrasion or scrubs, not high-frequency current.
- B. Hair removal is typically done with electrolysis or laser, not high-frequency current.
- C. Galvanic current or microcurrents are used for muscle toning, not high-frequency current.
