Performance and Safety of Amino-Acid- and Hydroxyapatite Enriched-Hyaluronic Acid Intradermal Gel in Facial Skin Defects

Background and Objectives: The facial skin defects associated with aging are common concerns in the aging population. Hyaluronic-acid-based intradermal gels have established themselves as safe and effective treatments for addressing these concerns. Recently developed enriched products aim to enhance the efficacy of these gels, yet their effectiveness lacks thorough validation in the existing literature. Materials and Methods: In this retrospective analysis, we investigated the outcomes of intradermal gel treatments in 103 patients with soft tissue defects. This study included three groups: 35 patients received amino-acid-enriched hyaluronic acid gel, another 35 were treated with hydroxyapatite-enriched hyaluronic acid gel, and the remaining 33 underwent hyaluronic acid treatment only. The efficacy of the treatments was assessed using the Global Aesthetic Improvement Scale (GAIS) score, while patient satisfaction was gauged through a detailed questionnaire. Any adverse event was monitored. Results: The treatments demonstrated remarkable efficacy, as evidenced by mean GAIS scores of 1.714 points for those treated with amino acid-enriched hyaluronic acid gel, 1.886 points for individuals receiving hydroxyapatite-enriched hyaluronic acid gel, and 1.697 for those treated with hyaluronic acid alone, all showing statistical significance (p < 0.0001). Patient satisfaction was very high. Significantly, there were no recorded instances of major adverse events. Conclusions: Hyaluronic gels, particularly those enriched with amino acids and hydroxyapatite, are effective and safe interventions for addressing facial skin aging defects. They serve as valuable tools in mitigating age-related blemishes and contribute to the overall improvement of skin aesthetics.

Low Molecular Weight Hyaluronic Acid Added to Six Specific Amino Acids in the Treatment of Striae Alba (SA): An Observational Study

Striae distensae or stretch marks are a common complaint among women and can be distressing. The present study aimed to assess the efficacy of a mixture of low molecular weight hyaluronic acid and six amino acids when applied with a specific intradermal injection technique known as intra-mural fluid technique. A clinical study was carried out in 32 patients (with a dropout rate by 9.4%) with striae distensae alba (SA) in one or more of the following anatomical areas: breast, abdomen, inner thigh, trochanteric area, gluteal area, posterior supra-iliac area, and lumbar area. Product efficacy was assessed by the investigator using the Global Aesthetic Improvement Scale, while a Likert scale was used to evaluate to score the treatment tolerability and a QoL stretch marks questionnaire was used to investigate the patients' self-body image. The treatment was effective in improving the appearance of SA fifteen days after the second treatment and 6 months after the first treatment (and after a total of 4 treatments). The product efficacy and tolerability were also perceived by the patients during each treatment session. Our results suggest that the test treatment is a valid treatment option to decrease the appearance of SA.

Evaluation of a Combination Approach to Improving Muscle Tone and Decreasing Subcutaneous Tissue Thickness Using a Sequential, Dual-Modality, Energy-Based Device

Background

The body shaping market has long been at the forefront of the aesthetic industry. With technological advances, patient demand for body sculpting in terms of reduction in subcutaneous tissue and enhancement of muscle has seen continual growth. Several devices have emerged in the space; however, few achieve both subcutaneous tissue reduction (SQR) and voluntary muscle increase (VMI) as measured by thickness, during the same treatment session.

Objectives

This article presents the results of a pilot study on a unique approach to subcutaneous tissue reduction and increasing muscle thickness using a dual-modality, energy-based device.

Methods

Twelve compliant patients (8 females and 4 males with an average age of 40 years) were enrolled in this single center, prospective study. All patients were treated with the dual-modality device (850 nm superluminescent diode matrix and electrical muscle stimulation), with external applicators being placed over the lower abdomen. The patients received 5 weekly treatments. Ultrasound measurements, photographs, weight, and waist measurements were taken at baseline, prior to the start of the fifth treatment, and at the 2-week and 2-month follow-up visits.

Results

At the 2-month follow-up visit, the average SQR was 34.03% and the VMI measured 22.97% in all patients who completed the study. All patient and physician evaluations rated the results as satisfactory or better. There were no complications.

Conclusions

Preliminary data show this dual-modality, electrical muscle stimulation/superluminescent diode matrix system provides both a safe and effective treatment for the reduction of subcutaneous tissue thickness and an increase in muscle definition and thickness. Objective and subjective evaluations demonstrated high levels of efficacy and satisfaction in all patients.

Needle-free electronically-controlled jet injector treatment with bleomycin and lidocaine is effective and well-tolerated in patients with recalcitrant keloids

OBJECTIVES

The treatment of recalcitrant keloids is challenging. Although intralesional bleomycin using conventional needle injectors (CNI) is effective, it has important drawbacks, such as the need for repetitive and painful injections. Therefore, we aimed to evaluate the effectiveness, tolerability and patient satisfaction of intralesional bleomycin with lidocaine administered with a needle-free electronically-controlled pneumatic jet-injector (EPI) in recalcitrant keloids.

METHODS

This retrospective study included patients with recalcitrant keloids who had received three intralesional EPI-assisted treatments with bleomycin and lidocaine. Effectiveness was assessed using the Patient and Observer Scar Assessment Scale (POSAS) at baseline and four to six weeks after the third treatment. Additionally, treatment related pain scores numeric rating scale, adverse effects, patient satisfaction and Global Aesthetic Improvement Scale (GAIS) were assessed.

RESULTS

Fifteen patients with a total of >148 recalcitrant keloids were included. The median total POSAS physician- and patient-scores were respectively 40 and 41 at baseline, and reduced with respectively 7 and 6-points at follow-up ( p < 0.001; p < 0.001). The median pain scores during EPI-assisted injections were significantly lower compared to CNI-assistant injections, (2.5 vs. 7.0, respectively ( p < 0.001)). Adverse effects were mild. Overall, patients were "satisfied" or "very satisfied" with the treatments (14/15, 93.3%). The GAIS was "very improved" in one patient, "improved" in nine patients and "unaltered" in four patients.

CONCLUSIONS

EPI-assisted treatment with bleomycin and lidocaine is an effective, well tolerated, patient-friendly alternative for CNI in patients with recalcitrant keloid scars. Randomized controlled trials are warranted to confirm our findings and improve the clinical management of recalcitrant keloids.

Needle-Free Jet Injector-Assisted Triamcinolone Treatment of Keloids and Hypertrophic Scars is Effective and Well Tolerated in Children

BACKGROUND

Keloids and hypertrophic scars can cause severe pain, pruritus, and psychological distress. Conventional intralesional corticosteroid treatment with needle injections remains challenging, especially in children with needle phobia.

OBJECTIVE

We aimed to evaluate the effectiveness, tolerability, and patient satisfaction of intralesional treatment with triamcinolone acetonide using a needle-free electronic pneumatic jet injector in children with keloids and hypertrophic scars.

METHODS

A retrospective study was performed in children with keloids and hypertrophic scars who received intralesional triamcinolone acetonide treatments using an electronic pneumatic jet injector. Effectiveness was evaluated using the Patient and Observer Scar Assessment Scale and Global Aesthetic Improvement Score at follow-up versus baseline. Tolerability was assessed with reported adverse effects and injection-related pain using a visual analog scale. Satisfaction questionnaires were used to evaluate treatment-related patient satisfaction.

RESULTS

Six female patients and five male patients aged 5-17 years, with a total of >118 keloids or hypertrophic scars were included. Electronic pneumatic jet injector treatment led to a significant reduction in the total Patient and Observer Scar Assessment Scale observer and patient scores compared with baseline, with a median reduction of 28.9% and 23.8%, respectively (p = 0.005; p = 0.009). Median visual analog scale pain scores for electronic pneumatic jet injector treatment were significantly lower compared with needle injections, 3.0 versus 7.0, respectively (p = 0.027). No severe adverse effects were reported. Overall, 6 patients were 'satisfied' and five patients were 'very satisfied' with the treatment.

CONCLUSIONS

Electronic pneumatic jet injector-assisted intralesional triamcinolone acetonide is an effective and well-tolerated treatment for keloids and hypertrophic scars in children. It should be considered as an alternative non-traumatic delivery method, especially in children with needle phobia or severe pain during previous needle injections.

Clinical and Ultrasound Evaluation of Skin Quality After Subdermal Injection of Two Non-Crosslinked Hyaluronic Acid-Based Fillers

Introduction

Nowadays patients want to get an immediate result from skin rejuvenation techniques without sign of injections and consequent limitations in social life. Therefore, the least traumatic, more effective, and longer lasting treatment approach for skin quality improvement should be favored.

Purpose

Assess skin quality outcomes by clinical examination and self-reporting in patients treated with two non-crosslinked hyaluronic acid (HA) products, injected by cannula. Investigate the skin thickness and the longevity of dermal fillers in soft tissues by ultrasound examination.

Patients and Methods

Fifteen female patients (mean age 41 years) were selected for injection with two non-crosslinked HA products (one for each hemiface and hemi neck). Subdermal injections were performed bilaterally and the retrograde linear fanning technique with a 25G 50 mm cannula from three entry points was used. An ultrasound examination of the skin layers thickness was carried out before the procedure and every 6-7 days up to three weeks, when patients skin quality improvement was assessed by GAIS (Global Aesthetic Improvement Scale) and patients asked about their satisfaction level.

Results

On the right hemiface, the use of the non-crosslinked HA-product with lidocaine was not associated with pain in the sites of injection. On both face sides, the signs of bruising or edema were minor and not associated with downtime or social life limitation after the procedure. After three weeks, despite both injected products could not be detected by ultrasound technique, signs of skin stimulation and skin layers hydration were still observed: The dermis became thicker on both hemifaces while the epidermis became thinner but showed more pronounced radiance and densification effect on the right hemiface.

Conclusion

Subdermal injections of non-crosslinked HA "skin boosters" could be a good option for minimal traumatic and effective 3-week lasting skin quality improvement.

Non-Surgical Lower Face Contouring in an Indian Patient: A Case Study

A 31-year-old Indian female patient presented with a ptotic face with signs of lower face ageing. She was concerned about sagging, an older look, and blunting of the jawline. She wished to have a more oval and narrow face contour. After the evaluation of the patient, we decided to perform a sequential treatment. Initially, the lower face was debulked with high-intensity focused ultrasound (HIFU). Following that, the jawline reshaping (JR) and malar reshaping (MR) techniques were performed with Definisse double needle 12 cm poly-ε-caprolactone-co-l-lactic acid (PCLA) threads. Lower-face hyaluronic acid (HA) filler injections were given for final contouring. Global Aesthetic Improvement Scale (GAIS) and subject level of satisfaction scores showed consistent improvement with the sequential procedures and at the six-month follow-up. Overall, the treatment procedures were uneventful and without any major adverse events. The current case of an Indian patient with a ptotic face and evident signs of lower face ageing showed improvement with a combination of procedures including Definisse threads.

Carbon Peeling Laser Treatment to Improve Skin Texture, Pores and Acne Lesions: A Retrospective Study

Carbon peel laser treatment has been described for the improvement of skin texture, with pore reduction and acne lesion treatment. The technique consists of applying a carbon mask to the face for about ten minutes followed by laser irradiation with a Q-switched 1064 nm laser. This mechanism of action seems to be related to small carbon molecules binding both the corneocytes and serum within the hair follicles; the effect of the laser eliminates carbon bound to skin particles and the high temperature generated reduces sebum production by sebaceous glands and inhibits Cutibacterium acnes replication. Although this method was described 20 years ago, scientific data supporting its efficacy and safety have only recently been reported in small case series. For this reason, we performed a retrospective study including patients treated from January to May 2022 in the context of a private practice. Even if this study is limited by the low number of patients and its retrospective nature, this is the first research to show that carbon peel laser, performed with a standardized technique, is an effective and safe treatment for patients with acne lesions, showing pores and wrinkles, and is able to improve the overall skin aspect.

Hyaluronic Acid Compound Filling Plus Mesotherapy vs Botulinum Toxin A for the Treatment of Horizontal Neck Lines: A Multicenter, Randomized, Evaluator-Blinded, Prospective Study in Chinese Subjects

Background

Although energy devices and botulinum toxin A (BTX-A) can alleviate age-related laxity, ptosis, and platysmal bands, they have limited efficacy on horizontal neck lines.

Objectives

The purpose of this study was to investigate the efficacy, safety, and subject satisfaction of a combined treatment of non–cross-linked hyaluronic acid (HA) compound filling plus mesotherapy for the correction of horizontal neck lines, in comparison with BTX-A.

Methods

This multicenter, randomized, evaluator-blinded, prospective study enrolled female patients with moderate-to-severe horizontal neck lines corrected with either 2 or 3 sessions of of non–cross-linked HA compound filling plus mesotherapy or 1 session of BTX-A injection. Improvement of the neck lines grades, Global Aesthetic Improvement Scale (GAIS), patient satisfaction, and adverse events (AEs) were evaluated and compared at 1, 3, 6, and 10 months after the final treatment.

Results

Twenty-five patients received HA filling plus mesotherapy and 23 received BTX-A injection. Compared with BTX-A, the HA compound filling plus mesotherapy significantly improved the horizontal neck lines grades on all follow-up visits (P = 0.000). Cases of different baseline grades (2, 2.5, and 3) demonstrated similar outcomes. The GAIS and patients’ satisfaction ratings were significantly higher for the HA filling plus mesotherapy treatment group (P = 0.000). Significantly higher pain ratings, higher incidence, and longer recovery of AEs (erythema, edema, and ecchymosis) were noticed in the combined treatment group (P < 0.001). No serious AEs occurred.

Conclusions

Compared with BTX-A, combined treatment with HA compound filling plus mesotherapy significantly improved moderate-to-severe horizontal neck lines and achieved a high level of patient satisfaction.

Guided Internal Fixation Technique for Transconjunctival Orbital Fat Transposition

ABSTRACT

The predominant method for transconjunctival orbital fat transposition is by conducting 1 or several temporary externalized sutures. A new method that could internally and more securely fixate the fat to the periosteum remains desirable. This manuscript introduces a technique that utilizes a titanium ring to guide transconjunctival orbital fat fixation for lower blepharoplasty. With 8 to 10 mm transconjunctival incisions, the orbicularis retaining ligaments were released. An intraoperatively made ring guided the sutures that was made transcutaneously and anchored on the periosteum to exit the preseptal space through the transconjunctival incision. The orbital fat graft was then fixated internally by this suture. From October 2017 to November 2019, 51 patients were included in this study. The mean patient age was 35.7 years (ranged 28-42 years). The mean operative time for the surgical procedure was 52 minutes. No major complications were noticed in any patients. There was 1 case in which the eye bag relapses at fifth week postoperatively, but was corrected by the same approach. At the average follow-up period of 12.1 months, all patients presented significant improvement of the lower eyelid cosmesis. Forty-four patients rated the aesthetic outcomes as "Very Satisfied," the other 7 rated "Satisfied" in a self-assessment questionnaire.Global Aesthetic Improvement Scale echoed similar outcomes. This guided internal fixation technique is technically practical when properly executed. It offers a new method for facilitating orbital fat transposition in lower blepharoplasty.
