Summary

This is a single-center, prospective, randomized controlled trial conducted at Huashan Hospital, Fudan University. The purpose of this study is to compare the effectiveness and safety of two non-invasive treatment options-1064-nm fractional picosecond laser and intense pulsed light (IPL)-for facial rejuvenation. A total of 38 participants seeking cosmetic improvement were randomly assigned to receive three sessions of either picosecond laser or IPL treatment at 4-6 week intervals.

Each participant was monitored throughout the treatment period and at one month after the final session. The study assessed improvements in skin texture, pigmentation, and wrinkles, as well as treatment-related side effects. All participants provided informed consent and received standardized post-treatment care instructions, including moisturization and sun protection. The results of this study may help guide non-surgical treatment options for skin aging.

Interventions

DEVICE

1064-nm Fractional Picosecond Laser (PicoWay)

Intervention Name: 1064-nm Fractional Picosecond Laser (PicoWay) Participants in this group received full-face treatments using a PicoWay® laser system (Candela, Wayland, MA, USA) equipped with a 1064-nm RESOLVE fractional handpiece. Treatment parameters included a 6 mm spot size, 6 Hz repetition rate, 450 ps pulse duration, and energy settings ranging from 1.5 to 2.3 mJ per microbeam. Each session consisted of 2-3 passes (approximately 2000-4000 pulses), adjusted based on individual response. Three sessions were delivered at 4-6-week intervals. Cold compresses were applied for 20 minutes immediately post-treatment.

DEVICE

Intense Pulsed Light Therapy (M22 IPL System)

Intervention Name: Intense Pulsed Light Therapy (M22 IPL System) Intervention Description: Participants in this group underwent full-face treatments using an M22® IPL system (Lumenis, Yokneam, Israel) with a 560 nm cutoff filter. Treatment parameters included a pulse duration of 3.5-4 ms, pulse delay of 25-30 ms, and fluence of 12-18 J/cm², adjusted based on individual response. Each treatment involved approximately 40-60 pulses. Three sessions were performed at 4-6-week intervals. A layer of medical ultrasound gel was applied before treatment and maintained for 15-20 minutes post-treatment.
