NIC Esthetician Written ExamTreatment ProceduresMedium
A client with Fitzpatrick skin type IV is interested in improving hyperpigmentation and overall skin texture. She is concerned about aggressive treatments due to her skin type's propensity for post-inflammatory hyperpigmentation (PIH). Which of the following electrical modalities would be MOST appropriate for a gentle, progressive approach?
- AGalvanic current (disincrustation)
- BHigh-frequency current
- CMicrodermabrasion
- DUltrasonic skin scrubber
Show answer & explanationAnswer & explanation
Correct answer: D. Ultrasonic skin scrubber
An ultrasonic skin scrubber uses high-frequency sound waves to gently exfoliate and deeply cleanse the skin without harsh abrasion or chemicals, making it suitable for sensitive skin types prone to PIH. It helps improve texture and product penetration.
Why the other options are wrong
- A. Galvanic desincrustation is primarily for softening sebum and facilitating extractions, not directly for hyperpigmentation or general texture improvement in this context.
- B. High-frequency current is primarily for antiseptic, healing, and stimulating effects, not for exfoliation or direct hyperpigmentation treatment.
- C. Microdermabrasion can be too aggressive for Fitzpatrick IV if not performed carefully, potentially leading to PIH.
Ultrasonic Skin Scrubber
An electrical modality that uses high-frequency sound waves to gently exfoliate, cleanse, and aid in product penetration without harsh abrasion.
- Gentle and non-invasive.
- Suitable for sensitive skin and darker skin types.
- Helps remove dead skin cells and debris.
- Enhances absorption of serums and moisturizers.
