Efficacy of Radiofrequency Microneedling
| Study | Technique | Aesthetic target | Summary/outcomes |
|---|---|---|---|
| Kim et al33 | Fractional radiofrequency microneedling | Periorbital wrinkles | Significant reduction in wrinkles and improvement in satisfaction |
| Lee et al34 | Fractional radiofrequency microneedling | Periorbital wrinkles | All patients were satisfied with treatment and most received clinical and photographic assessment improvement |
| Kwon et al35 | Monopolar radiofrequency microneedling | Periorbital wrinkles | Long microneedling is preferable to short microneedling and results in significantly improved photographic assessments |
| Jeon et al36 | Fractional radiofrequency microneedling | Periorbital wrinkles | Long-term results for improvement of periorbital wrinkles are superior in microneedling in comparison to botulinum toxin |
| Gold et al37 | Fractional radiofrequency microneedling | Mid- and lower face laxity and wrinkles | Significant wrinkle reduction, skin tightening, and lifting of the mid- and lower face resulted from the treatment |
| Alexiades et al38 | Bipolar fractional radiofrequency microneedling | Face and neck rhytides and laxity | Temperature-controlled bipolar radiofrequency results in high levels of patient satisfaction, and significant reduction in wrinkles and skin laxity |
| Zhang et al39 | Fractional radiofrequency microneedling | Facial photoaging | There were high levels of patient satisfaction and significant improvements in 2 measures of facial photoaging (rhytides, skin tightening, complexion) |
| Liu et al40 | Fractional radiofrequency microneedling | Rhytids and facial laxity | 3-Dimensional imaging revealed improvement in roughness parameters as an indication of treatment efficacy in photoaging |
| Seo et al41 | Fractional radiofrequency microneedling | Skin rejuvenation | Objective measures (skin hydration, roughness, histological findings dermal thickness, collagen content) and subjective measures (patient satisfaction) all improved after treatment |
| Alexiades et al42 | Fractional radiofrequency microneedling | Facial and neck rhytides | Treatment had a 100% response rate, identifying an optimal dermal temperature of 67°C with a duration of 3 to 4 s |
| Lu et al43 | Fractional radiofrequency microneedling | Nasolabial and infraorbital rhytides | Treatments targeting the deep dermal layer were more effective than superficial, and nasolabial folds responded to treatment more than infraorbital rhytids |
