Background:
Post-procedural ecchymosis can last up to two weeks and diminish patient satisfaction. Laser-assisted clearance is documented with pulsed-dye devices, but data on 1064-nm picosecond/nanosecond platforms remain sparse.
Objective:
To evaluate a staged 1064-nm laser protocol for accelerating bruise resolution after dermal filler injections.
Methods:
Three women (aged 40-52 years, Fitzpatrick III-IV) with facial bruises were treated on Day 2-3 using a picosecond 1064-nm Nd:YAG laser (0.20-0.30 J/cm², 8-10 mm spot, 8-10 Hz, 8-10 min). A nanosecond Q-switched 1064-nm Nd:YAG session followed on Day 4-7 (2.5-3.0 J, 8 mm spot, 30-40 stacked shots) with peri-session cooling. Clinical photographs and Global Aesthetic Improvement Scale (GAIS) ratings were obtained through Day 7.
Results:
All bruises faded substantially within 4-5 days; near-complete resolution was achieved by Day 6-7. GAIS scores were "Much" or "Very Much Improved" in every case. No pain, post-inflammatory hyperpigmentation, or other adverse effects occurred. Compared with typical spontaneous recovery (≈10-14 days), the protocol shortened visible downtime by 40%-60%.
Conclusion:
A sequential 1064-nm picosecond-nanosecond regimen appears safe and effective for rapid ecchymosis clearance after aesthetic injections. Larger controlled studies are warranted to optimise fluence, cost-effectiveness, and applicability to other procedural bruises and darker skin types.
