“…Cadaveric dissections that have carried out as preliminary proof of concept (data not shown), revealed the fatty area at the level of the lip was hardly present which in accordance with Blandford et al that reported HA gel filler augmentation of the vermillion border may result in filler location within the muscle and this injection plane seems safe regarding the location of the superior labial artery. 21 In a recent study performed on 41 healthy volunteers, Cotofana et al pointed out the most frequent location of labial arteries was the submucosal followed by intramuscular planes (58.5% and 36.2%, respectively). 13 Since Stylage M has a high elastic modulus (G′), it is suitable for deep implantation and a volumizing effect.…”

Introduction Lip augmentation is achieved mainly by using hyaluronic acid (HA) fillers. The injection procedures are performed either superficially or deeply with a needle or a cannula, and only one type of hyaluronic acid is used. The authors' objective was to evaluate the feasibility, safety, and satisfaction level of a procedure combining two anatomical injection plans, two injection modes (i.e., cannula and needle), and two types of hyaluronic acid fillers. Method The retrospective study included 30 patients who underwent the following procedure: Intramuscular retro‐trace injections of Stylage M (Vivacy® Laboratories) were conducted through a 27‐gauge cannula at the level of the upper and lower hemi‐lip. Then, intradermal injections of Stylage Lips (Vivacy® Laboratories) using a 33‐gauge needle were carried out on the entire lip border as well as the cupid's bow. During a post‐injection follow‐up, subjects were asked to evaluate satisfaction level and the effect of fillers over time. Elastic (G′) and viscosity (G″) moduli of HA fillers were measured with a rheometer (AR2000, TA Instruments) prior to and after extrusion through a 33‐gauge needle. Results Rheological assessment showed that passage through a 33‐gauge needle did not alter the viscoelastic properties of HA fillers. After the clinical procedure, no side effects were observed except for standard post‐treatment bruises and edema. No vascular incident occurred. Moreover, overall patient satisfaction was high (2.6/3) and there was a long‐lasting perception of the effect of the filler. Conclusion The current study demonstrated that dissociating the anatomical zones of the lip during the injection procedure by means of different hyaluronic acids in the muscular and dermal planes would efficiently and safely provide both lip projection and fullness for a natural and lasting effect.

Introduction: Lip augmentation procedures with hyaluronic acid dermal fillers have become increasingly popular worldwide because full lips are often considered beautiful and youthful. The goal of a lip augmentation procedure is to create smooth lips with adequate volume and a natural appearance. Various techniques for lip augmentation have been utilized and described. Methods: In the four-point injection technique, the lips were divided equally into right side and left side. Four entry points were made above the vermilion border for the upper lip and below the vermilion border for the lower lip. The filler was administered with a fanning technique through each entry point. Results: Between January 2017 and November 2017, 50 female patients underwent a nonsurgical lip augmentation procedure with injectable fillers using this technique. Forty-five patients (90%) reported that they were satisfied or extremely satisfied with their lip enhancement procedure. No serious complications were observed. Conclusion:The advantages of this technique are reducing the risk of complications like erythema, edema, and vascular injuries, and providing easy access to injection sites.

Beautiful lips are responsible for facial attractiveness and a youthful appearance. During aging process, lips become thinner and the red lips borders get poor defined. Downturn of the corners of the mouth suggests negative emotions. Lip surgery and underlying pathology may result in asymmetries and lip incontinence. Minor invasive procedures with hyaluronic acid fillers and botulinum toxin A are versatile tools to improve appearance of the lips, restore function and improve psycho-social wellbeing. In this review, we discuss anatomy, safety concerns, injections techniques as well as esthetic and medical indications.
