What each handle on a multifunction facial machine does
High frequency
A glass electrode filled with argon or neon gas carries a low-current, high-frequency charge that produces ozone at the skin surface. Used for acne-prone skin, post-extraction and scalp work. On the 14-in-1 (high-frequency wand) and the WD40 on the Facial Machines page (0.2 to 0.5 MHz HR handle).
Microcurrent
Two probes pass a current measured in microamps through facial muscles for a temporary lifted look and a brightening effect; the "non-surgical facelift" add-on. On the 7-in-1 Hydro Facial and Plasma (microcurrent probe) and the 8-in-1 Hydro Dermabrasion and Skin Analysis.
Oxygen spray and oxygen infusion
A pressurized mist of serum or oxygenated water, used as a hydration finish after exfoliation. Oxygen sprayer on the 7-in-1 HydroSpa, oxygen spray gun on the 14-in-1, oxygen bubble and water-oxygen handles on the 8-in-1.
Ultrasonic and ultrasound
A flat ultrasonic inducer vibrates to help serums spread and settle; a skin scrubber uses the same vibration with a spatula edge to lift debris. The 14-in-1 adds a dedicated eye ultrasound attachment. Ultrasonic cavitation on the two 9-in-1 systems is the body version at a lower frequency.
Galvanic and ion
Direct current drives water-based product into the skin (iontophoresis) or draws out impurities (desincrustation). The 7-in-1 Hydro Facial and Plasma includes an ionic spray pen; the 14-in-1 includes a detox pen.
Radio frequency
Bipolar or tripolar RF warms the dermis for a firming effect. Bipolar RF handles on the 7-in-1 Hydro Facial and Plasma, 8-in-1 Skin Analysis and both 9-in-1 systems; a tripolar RF wand on the 14-in-1; three probe sizes on the ML600.
Plasma
Hot and cold fusion plasma, jet plasma and flake plasma tips on the 8-in-1 Hot and Cold Fusion system; a plasma probe on the 7-in-1 Hydro Facial and Plasma. Covered in detail on the Plasma Facial Machines page.
LED, hot and cold hammer, skin analysis
LED masks (7 colors on the 7-in-1 Hydro Facial and Plasma) and photon heads for post-treatment calming; cold hammers to close pores and reduce redness; a 2 megapixel skin analysis lens on the 8-in-1 for consultations.
