NIC Esthetician Written ExamTreatment ProceduresEasy
A client with oily, acne-prone skin and minor scarring from past breakouts is interested in a facial treatment that deeply cleanses pores, reduces bacteria, and promotes healing. The esthetician is considering an electrical modality that generates ozone. Which modality is MOST suitable for this client's concerns?
- AHigh-frequency current
- BMicrocurrent
- CLED therapy (blue light)
- DGalvanic current
Show answer & explanationAnswer & explanation
Correct answer: A. High-frequency current
High-frequency current creates ozone when the electrode is placed on the skin, which has a germicidal and antiseptic effect beneficial for acne-prone skin. It also stimulates circulation and promotes healing, addressing the client's concerns for deep cleansing, bacteria reduction, and healing.
Why the other options are wrong
- B. Microcurrent is for muscle re-education and toning, not for antiseptic or acne treatment.
- C. Blue LED light is effective for killing P. acnes bacteria, but high-frequency also provides ozone (germicidal) and overall healing/stimulating benefits, fitting 'electrical modality' better and encompassing more of the client's needs.
- D. Galvanic current is used for desincrustation (softening sebum) or iontophoresis (product penetration), not primarily for germicidal effects.
High-Frequency Current (Acne)
An alternating current electrical modality that generates ozone and heat, providing germicidal, antiseptic, stimulating, and healing benefits for acne-prone and oily skin.
- Generates ozone for germicidal action.
- Increases circulation and cellular metabolism.
- Helps dry out pustules and promotes healing.
- Used directly or indirectly with a glass electrode.
