A client with Fitzpatrick skin type II presents with concerns about fine lines and a dull complexion. She is interested in a non-invasive treatment that can improve skin texture and promote collagen production. Which electrical modality would be most suitable for this client?
- AMicrodermabrasion
- BGalvanic current (iontophoresis)
- CGalvanic current (desincrustation)
- DHigh-frequency current
Show answer & explanationAnswer & explanation
Correct answer: A. Microdermabrasion
Microdermabrasion is a mechanical exfoliation technique that removes dead skin cells, stimulating cell turnover and promoting collagen production, which effectively addresses fine lines and dullness.
Why the other options are wrong
- B. Iontophoresis uses galvanic current to penetrate products, not to mechanically exfoliate or directly stimulate collagen for fine lines.
- C. Desincrustation uses galvanic current to soften sebum and is primarily for oily/congested skin, not fine lines.
- D. High-frequency current is used for antiseptic effects, oxygenation, and calming, not direct collagen stimulation or exfoliation for fine lines.
