Radiofrequency for skin

Real improvement in small trials. No sham-controlled trial yet.

Clinic devices heat the skin with radiofrequency — through tiny needles (RF microneedling, such as Jeisys Potenza) or from the surface (monopolar RF, and Jeisys Density, which pairs monopolar with bipolar). Short answer: acne scars, wrinkles and laxity improved after treatment in many small studies, and RF microneedling did about as well as a CO2 laser on scars. But no trial we found compared any of them with a sham treatment, so the size of the device’s own effect is unmeasured. Potenza’s “up to 60%” comes from a 12-person study with no comparison group; Density’s collagen figures have no published source we could find.

Before booking: ask how many sessions, what downtime and side effects to expect for your skin type (darker skin can scar or darken after heat treatments), and the total price.

What the research shows

Grades are calculated from the studies listed, by fixed rules.

RF microneedling improves acne scarsEarly evidence
Scars improved after RF microneedling in many small studies, and in a split-face trial one session did as well as a CO2 laser — about one point on a ten-point texture scale. No trial compared it with a sham treatment, so how much is the device and how much is time and expectation is not measured.
- Open-label randomized trial, 15 people, 13 weeks (2023) — primary outcome: improved. Funder not checked.
- Narrative review, 481 people (2025) — primary outcome: improved. Funded by independent sources. Not counted toward the grade.
RF microneedling smooths wrinkles and tightens sun-aged skinEarly evidence
The study Potenza cites treated 12 people three times and found tighter skin, better texture and more organised collagen on biopsy — with no comparison group. That is a starting point, not proof.
- Case series, 12 people, 12 weeks (2025) — primary outcome: improved. Funder not checked.
Monopolar radiofrequency tightens facial skinEarly evidence
In two randomized trials, laxity or fold depth improved after treatment and the devices compared did about the same. Neither had an untreated or sham group, so the trials show the devices match each other, not how much either beats doing nothing.
- Open-label randomized trial, 20 people, 26 weeks (2019) — primary outcome: improved. Funder not checked.
- Open-label randomized trial, 40 people, 26 weeks (2025) — primary outcome: improved. Funder not checked.
Potenza RF microneedling delivers “up to 60% improvement in texture, wrinkles, and laxity after 1-3 sessions”Early evidence
The figure is footnoted to the 12-person study above, which had no comparison group; “up to” is the best result, not the typical one. Potenza’s own page gives its cleared use as electrocoagulation and hemostasis, with the cosmetic effects described as coming from that.
- Case series, 12 people, 12 weeks (2025) — primary outcome: improved. Funder not checked.
Jeisys Density raises collagen fiber density by 76% and builds “up to 5x more collagen than monopolar RF alone”No real evidence
We found no published study of Density on PubMed, and its page does not say where the 76%, 82%, 239% or “5x” figures come from. More collagen in a biopsy is also not the same as skin that looks firmer.
