4D Lips Technique Based on Anatomy for Naturalization.

BACKGROUND

Lip augmentation has become a cornerstone of aesthetic procedures, particularly among younger patients seeking to enhance their natural lip features. A precise anatomical approach is essential to achieve balanced, natural-looking results while minimizing the risk of complications. This study introduced the 4D Lips technique, a multiphasic hyaluronic acid filler method designed to enhance lip shape while respecting anatomical landmarks. The technique is guided by 4 fundamental principles-dimension, distribution, dynamics, and desire-to ensure harmonious and individualized outcomes.

METHODS

Ten female patients underwent lip augmentation using a combination of subtechniques, including tubercle marking, vertical elongation, and vermilion border eversion. Two hyaluronic acid fillers with distinct viscoelastic properties were used: one with medium G' for structural support and another with low G' for contour refinement. Patient satisfaction and safety outcomes were systematically evaluated.

RESULTS

All patients reported satisfaction with the natural appearance of their enhanced lips. Mild and transient side effects, such as swelling, were observed and resolved spontaneously within a few days. No major complications were recorded. The structured, anatomy-based approach allowed for precise volumization, refined contouring, and preservation of natural lip dynamics.

CONCLUSIONS

The 4D Lips technique underscores the value of an anatomy-informed and personalized approach to lip augmentation. By combining structural enhancement with a patient-centered perspective, this method achieves high satisfaction rates and a favorable safety profile. Nonetheless, the limitations of the study, including the small sample size, absence of a control group, and lack of long-term follow-up, warrant further investigation to validate these findings.
