The "4.3," A New Filler Lips Technique

Area of Science:

• Aesthetic Medicine
• Dermatology
• Cosmetic Surgery

Background:

• The "4.3" technique is a novel hybrid lip augmentation method.
• It merges the vertical-lip and retrograde linear techniques for enhanced aesthetics and fewer injection sites.
• Hyaluronic acid (HA)-based fillers are utilized for natural-looking lip volume and contour enhancement.

Purpose of the Study:

• To evaluate the "4.3" technique's effectiveness, safety, and reproducibility in lip augmentation.
• To assess its ability to achieve natural results with minimal filler volume and reduced injections.
• To minimize complication risks while improving lip shape and volume.

Main Methods:

• The "4.3" technique was applied to male and female patients seeking subtle lip enhancements.
• The procedure involved a total of seven injections (four upper lip, three lower lip).
• A consistent 0.7 mL of HA filler was used per patient, combining retrograde linear and vertical injection methods.

Main Results:

• The technique yielded consistent, aesthetically pleasing outcomes, improving lip volume, shape, and definition.
• A reduced number of injections led to minimized patient discomfort and lower risk of vascular complications.
• Tri-Hyal technology contributed to smooth, plump lips with harmonious proportions.

Conclusions:

• The "4.3" technique is a standardized, intuitive, and reproducible lip augmentation method.
• It is suitable for most patients seeking natural-looking results with less filler and fewer injections.
• The technique is a safe and effective option for enhancing lip aesthetics.
