First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study compares two devices—ePrime (radiofrequency) and Fraxel (laser)—to see which improves acne scars more. Each participant gets both treatments on different sides of their face, and a blinded dermatologist rates the results. The goal is to find a more effective way to reduce ice pick and boxcar scars.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- bipolar fractional radiofrequency (ePrime) and 1550-nm fractional photothermolysis (Fraxel)
- What this could lead to

- What could go wrong
- This is a small pilot study with only 16 participants, so results may not apply to everyone. Both treatments may cause temporary redness or swelling.
