The technique involves inserting poly L-lactide-co-ε-caprolactone bi-directional threads into anchor points near the zygomatic body, leveraging the structural support of ligaments and minimizing neurovascular risks. Immediate post-procedure results revealed significant improvements, with lateral mouth angles elevated by 0.3-0.5 cm and medial cheek points by 0.2-0.3 cm.

During the one-month follow-up, additional gains of 0.1-0.2 cm were noted at the same points, alongside enhanced skin quality and firmness. At six months, outcomes remained stable for patients without adjunctive procedures, maintaining high PSS scores (2-3). The study reinforces the retrograde reverse-vector method as a safe, effective option for midface rejuvenation.

This retrospective study evaluated 99 female patients with melasma, including 54 treated with PSNY laser and 45 with QSNY laser.

The PSNY laser produced a mean mMASI reduction of 23.7% and 40.7% after two and five sessions, respectively, while QSNY treatment achieved reductions of 9.8% and 29.5%. Although both modalities were safe and effective, PSNY laser demonstrated faster clinical improvement and required lower energy fluence.
