Aesthetic Treatment of the Lips With Hyaluronic Acid Filler: The Multi Vector Lip Technique

ABSTRACT Background Hyaluronic acid (HA) fillers are a key treatment in the augmentation and rejuvenation of the lips. The novel Multi Vector (MV) Lip technique has been developed using specific injection vectors in geometric forms to shape the lips—allowing precise customization according to the needs of individual patients. Aims To describe the MV Lip technique and evaluate its safety and effectiveness in patients treated across five centers in Brazil. Methods This was a retrospective analysis of data from adult female subjects. Eligible patients were treated using the HA filler, VYC‐17.5L, in multiple different zones of the lips and perioral area, based on predefined vectors filling geometric shapes. Results A total of 253 patients from a range of ethnic backgrounds were included (mean age: 41.0 ± 12.9 years). They received a mean of 1.06 ± 0.21 mL of VYC‐17.5L. On a scale from 1 (poor) to 4 (excellent), mean patient satisfaction with the result was 3.92 ± 0.28. Adverse events were minor cases of edema ( n = 40; 15.8%) and bruising ( n = 28; 11.1%). There were no major complications and no cases of vascular occlusion. Conclusions The MV Lip technique offers a safe, effective, and reproducible method that is sufficiently versatile to be used across all types of female lips.
