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?

  1. AHigh-frequency current
  2. BMicrocurrent
  3. CLED therapy (blue light)
  4. DGalvanic current
Show answer & 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.
