Evaluation of the Performance and Safety of a New Micro-Needle Technology in Comparison With the Classic Needle on the Antiaging Effects of a Biorevitalizing Solution: A Randomized Split Face/Neck Study. J Cosmet Dermatol 2024. [PMID: 39356623 DOI: 10.1111/jocd.16547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Revised: 07/23/2024] [Accepted: 08/12/2024] [Indexed: 10/04/2024]
Abstract
BACKGROUND Skin biorevitalization involves multiple intradermal injections to enhance skin quality, but precise dermal targeting can be challenging due to variations in skin thickness smaller, less painful needles with fewer skin reactions are attractive options. AIMS This study evaluates a new Micro-Needle device's performance and safety in comparison with the classic needle used in skin biorevitalization. PATIENTS/METHODS Subjects with facial and neck skin aging were enrolled. Safety outcomes, including immediate and local tolerability, were assessed. Performance outcomes measured skin radiance, wrinkles and photoaging grade, hydration, subepidermal low echogenic band, dermis thickness, and skin elasticity. Both subjects and investigators recorded Global Aesthetic Improvement Scale scores. RESULTS Micro-Needle injections demonstrated superior performance compared to the classic needle, influenced by the specific skin zones and thickness. Micro-Needle was superior for skin wrinkles at D49 for periorbital zone and nasolabial folds by -14.5% (p = 0.01) and -15% (p = 0.004), respectively, and for neck by 9.6% (p = 0.0008). The Nanosoft device showed a faster improvement for skin hydration at D42 for the cheek zone (p = 0.04) and at D75 for the neck area (p = 0.01); and for skin radiance at D75 (p = 0.03) and at D120 (p = 0.0098). Ex vivo studies confirmed the Micro-Needle's accuracy in product placement in the dermis. Adverse events were milder with Micro-Needle and no serious adverse events occurred. CONCLUSIONS Both needles significantly improved skin quality, but Micro-Needle enhanced the outcomes of skin biorevitalization procedures, particularly in terms of skin wrinkle reduction, elasticity, and overall skin hydration.

Abstract
BACKGROUND Various techniques have been employed in aesthetic medicine to combat skin aging, in particular that of the facial region. Hyaluronic acid is utilized to enhance moisture levels and extracellular matrix molecules. This study aims to histologically assess the effects of low molecular weight hyaluronic acid fragments combined with amino acids (HAAM) on facial skin rejuvenation through intradermal microinjections. METHODS A total of twenty women, with an average age of 45 and ranging from 35 to 64 years old, participated in the study, including 8 in menopause and 12 in the childbearing age group. Mesotherapy was used to administer HAAM to the patients. Prior to and three months after the treatment, each patient underwent small circular punch biopsies. Ultrasound examinations were conducted using B-mode, capturing 2D images in longitudinal or transverse orientations with frequencies ranging from 5 to 13 Mega-hertz (MY LAB X8, ESAOTE, Genova, Italy). A total of 60 ultrasound examinations were taken, with 30 collected before treatment and 30 after treatment. RESULTS The histological analysis demonstrates an increase in fibroblast activity resulting in the production of Type III reticular collagen, as well as an increased number of blood vessels and epidermal thickness. However, the analysis of ultrasound data before and after treatment showed no statistical difference in skin thickness in malar area, chin and mandibular angle. CONCLUSIONS Histological assessments indicate that subcutaneous infiltration of HAAM has a substantial impact on the dermis of facial skin.

Abstract
BACKGROUND The market requires ever-faster techniques, in particular for pre-rejuvenation condition. AIM The purpose of this study was to assess if a fractional CO2 scanner modality (called moveo) results in a faster full-face rejuvenation treatment in comparison to the standard mode, currently existing in the scanner system. MATERIALS AND METHODS A total of 12 female patients affected by fine lines participated in a split-face clinical investigation and underwent to two sessions with a fractional CO2 laser system equipped with an existing and a faster dedicated scanner units. Pain was assessed using VAS. Three-dimensional clinical photographs were captured before, immediately after, 3 days, 14 days after the first treatment and immediately after the second treatment and 1 months after the last one. The uniformity and aesthetic coverage of treatments were assessed using dermatoscopy. Global aesthetic improvement scale (GAIS) was used. The time taken to treat the two sides of the face and all possible side effects were monitored. RESULTS Following only two treatment session with both scanner modes, the patient's skin texture improved significantly, with fine lines reduction. There is no statistically significant difference in perceived pain between patients. The GAIS score showed satisfactory results following both modalities. The time parameters indicated that with the faster scanner mode the full-face treatment time was reduced by 30% compared to the standard one. No adverse effects were observed. CONCLUSIONS The moveo modality provide faster treatment and a better final dermal aesthetic outcome than the standard procedure while maintaining the same safety profile.

J Appl Oral Sci 2024; 32:e20230294. [PMID: 38747782 PMCID: PMC11093524 DOI: 10.1590/1678-7757-2023-0294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 02/24/2024] [Accepted: 03/12/2024] [Indexed: 05/19/2024] Open
Abstract
OBJECTIVE This study aims to develop a compound biomaterial to achieve effective soft tissue regeneration. METHODOLOGY Compound hyaluronic acid (CHA) and liquid horizontal-platelet-rich fibrin (H-PRF) were mixed at a ratio of 1:1 to form a CHA-PRF gel. Human gingival fibroblasts (HGFs) were used in this study. The effect of CHA, H-PRF, and the CHA-PRF gel on cell viability was evaluated by CCK-8 assays. Then, the effect of CHA, H-PRF, and the CHA-PRF gel on collagen formation and deposition was evaluated by qRT‒PCR and immunofluorescence analysis. Finally, qRT‒PCR, immunofluorescence analysis, Transwell assays, and scratch wound-healing assays were performed to determine how CHA, H-PRF, and the CHA-PRF gel affect the migration of HGFs. RESULTS The combination of CHA and H-PRF shortened the coagulation time of liquid H-PRF. Compared to the pure CHA and H-PRF group, the CHA-PRF group exhibited the highest cell proliferation at all time points, as shown by the CCK-8 assay. Col1a and FAK were expressed at the highest levels in the CHA-PRF group, as shown by qRT‒PCR. CHA and PRF could stimulate collagen formation and HGF migration, as observed by fluorescence microscopy analysis of COL1 and F-actin and Transwell and scratch healing assays. CONCLUSION The CHA-PRF group exhibited greater potential to promote soft tissue regeneration by inducing cell proliferation, collagen synthesis, and migration in HGFs than the pure CHA or H-PRF group. CHA-PRF can serve as a great candidate for use alone or in combination with autografts in periodontal or peri-implant soft tissue regeneration.

Abstract
BACKGROUND Although a composite solution of non-crosslinked hyaluronic acid is generally considered safe, few studies have investigated its safety after intravascular injection. METHODS Male Sprague-Dawley rats were administered 0.05 mL of a non-crosslinked hyaluronic acid composite solution via intravascular injection into bilateral inferior epigastric arteries (IEA). Artery samples were obtained at multiple time points for histopathologic analysis. Bilateral abdominal flaps supplied by the IEA were lifted and the same dose of solution was injected into the artery, and flap survival was analyzed. RESULTS Histopathologic analysis showed that the non-crosslinked hyaluronic acid composite solution remained temporarily in the artery lumen following intravascular injection. With continuous blood flow, the filler gradually disintegrated and the artery became recanalized. At 24 h, no filler remained in the lumen. At 7 days after the filler was injected into the IEA feeding the flap, there was no significant difference between the experimental and control groups with respect to flap survival rate. CONCLUSIONS Non-crosslinked hyaluronic acid composite solution is relatively safe when a minimal volume is administered by intravascular injection. The filler will remain in the vessel for a short time, after which the vessel recanalizes.

Abstract
Hyaluronic acid (HA)-based injectable filling agents are at the forefront of the current demand for noninvasive dermatological procedures for the correction of age-related soft tissue defects. The present review aims to summarize currently available HA-based products and critically appraise their differences in rheological nature and clinical application. Linear HA (LHA) gels may be supplemented with amino acids, lipoic acid, vitamins, nucleosides, or minerals for synergistic antiaging and antioxidant benefits (polycomponent LHA). HA hydrogels can be generated via chemical or physical crosslinking, which increases their elasticity and decreases viscosity. The performance of crosslinked fillers depends on HA concentration, degree of crosslinking, elastic modulus, cohesivity, and type of crosslinking agent employed. PEG-crosslinked LHA displays improved elasticity and resistance to degradation, and lower swelling rates as compared to BDDE-crosslinked LHA. Physical crosslinking stabilizes HA hydrogels without employing exogenous chemical compounds or altering hyaluronans’ natural molecular structure. Thermally stabilized hybrid cooperative HA complexes (HCC) are a formulation of high- and low-molecular-weight (H-HA and L-HA) hyaluronans, achieving high HA concentration, low viscosity with optimal tissue diffusion, and a duration comparable to weakly cross-linked gel. Our critical analysis evidences the importance of understanding different fillers’ properties to assist physicians in selecting the most appropriate filler for specific uses and for predictable and sustainable results.

Abstract
OBJECTIVE To establish a nude mouse model of photoaging and study the therapeutic effect of a concentrated growth factor preparation (CGF) on skin photoaging. METHODS CGF was prepared from blood from Sprague-Dawley rats. A skin photoaging nude mouse model was developed using UV irradiation combined with the photosensitizer, 8-methoxypsoralen. Mice were divided randomly into seven groups (n = 6 per group): normal control, photoaging, mock treatment, saline treatment, CGF treatment, Filoca 135HA treatment, and plasma skin regeneration system irradiation (the latter two were positive controls). Body weight and skin appearance were observed and pathological changes were determined by hematoxylin and eosin staining. Fiber elasticity was evaluated by Weigert staining. Expression levels of proliferating cell nuclear antigen (PCNA) and matrix metalloproteinase 1 (MMP1) were determined by immunohistochemistry. RESULTS A mouse model with typical features of photoaging skin was successfully developed. CGF significantly improved the skin appearance, wrinkle scores, pathological changes, and fiber elasticity, and increased PCNA and decreased MMP1 expression levels in photoaging mice, comparable to the two positive controls. CONCLUSION CGF can improve the symptoms of skin photoaging in mice, suggesting that it may have applications in the treatment of skin aging in humans.

Abstract
The multicomponent preparations for mesotherapy are based on the principle that skin and hair aging can be prevented by supplying the fundamental substrates for correct cellular functioning, such as nucleotides, vitamins, amino acids, and biomolecules including hyaluronic acid (HA) that promote skin hydration and several biological activities. The study provides evidence for the application of HYDRO DELUXE BIO (Matex Lab S.p.A), a biocompatible hydrogel containing not cross-linked HA, for the treatment of the scalp’s skin by mesotherapy. Using an in vitro model of immortalized human keratinocytes, we studied markers involved in hair aging prevention and growth, such as inflammatory markers, angiogenesis, and oxidative damage. HYDRO DELUXE BIO showed high biocompatibility and the ability to significantly reduce the expression of the inflammation marker interleukin (IL)-8 in Tumor Necrosis Factor (TNF)-stimulated cells. Then, we evaluated angiogenesis, a pivotal event during hair growth, measuring the Vascular Endothelial Growth Factor (VEGF) expression that resulted to be significantly increased in treated cells, suggesting a pro-angiogenetic capability. A protective activity against the oxidative stress agent was showed, increasing the survival rate in treated cells. Concluding, HYDRO DELUXE BIO is suitable for treatment by mesotherapy of the scalp’s skin as it modulates the expression levels of markers involved in the biorevitalization of the hair follicle.

Abstract
Aging leads to diminished capacity in the functionality of all the skin layers, which in turn leads to a structurally weak and esthetically unappealing skin which is dull, dehydrated, and inelastic. Skin boosters can be defined as biological materials or bio-actives that help or encourage the skin to increase or improve its function. Boosters have been used in treating skin structural changes associated with aging as well as other factors such as corticosteroid-induced skin atrophy. Restoring the loss in skin nourishment and vital components is the concept involved in biorevitalization of the skin. The authors aim to present an update and a short review of skin boosters in this commentary.

Abstract
This study was conducted according to the method presented in the Republic of Korea Pharmacopoeia 11th Revision, aseptic test method to evaluate the suitability of sterilization for a sterile needle (4 Pin Multi-needle). In this study, four tests were conducted: sterility test, cytotoxicity test, acute toxicity test, skin sensitization test. First, in the aseptic test, the microorganism was not proliferated in the aseptic test of the medium. As a result of the performance test of the medium, it was confirmed that the microorganism developed within 3 days and the fungus was evident within 5 days. Based on this, it was confirmed that the medium was suitable, and as a result of the aseptic test, the development of microorganisms was not observed during the total culture period. Based on these results, tests were conducted which were confirmed to be suitable for aseptic testing because the development of bacteria on the provided samples was not recognized. For cytotoxicity tests ISO10993-5; 2009 (Biological Evaluation of Medical Devices, Part 5: Test for in vitro Cytotoxicity). As a result, the MEM eluate of the test substance caused very slight cytotoxicity to the fibroblasts of the mouse and was judged to be Grade 1 (Slightly cytotoxic) according to the judgment standard of ISO 10993-5. On the other hand, solvent control, negative control and positive control showed the expected results on the test. Acute Toxicity Test Results: It was judged that there was no systemic toxicity change when ICR mice were treated with 50 mL/kg B.W. of the eluate of sterile injectable needle for 72 hours. Skin sensitization test result: The Hartley guinea pig was evaluated as a substance which is evaluated as a substance which does not induce any skin reaction when skin sensitization is applied to the dissected material of the sterile injectable needle and is weak in skin sensitivity. Based on the above tests, we will study the stability and efficacy of more reliable medical devices based on the verification and performance of medical devices.

Abstract
BACKGROUND A validated scale is needed for objective and reproducible comparisons of facial skin roughness before and after aesthetic treatment in practice and in clinical studies. OBJECTIVE To describe the development and validation of the 5-point photonumeric Allergan Skin Roughness Scale. METHODS The scale was developed to include an assessment guide, verbal descriptors, morphed images, and real subject images for each grade. The clinical significance of a 1-point score difference was evaluated in a review of image pairs representing varying differences in severity. Interrater and intrarater reliability was evaluated in a live-subject validation study (N = 290) completed during 2 sessions occurring 3 weeks apart. RESULTS A score difference of ≥1 point was shown to reflect a clinically meaningful difference (mean [95% confidence interval] absolute score difference 1.09 [0.96–1.23] for clinically different image pairs and 0.53 [0.38–0.67] for not clinically different pairs). Intrarater agreement between the 2 validation sessions was almost perfect (weighted kappa = 0.83). Interrater agreement was almost perfect during the second rating session (0.81, primary end point). CONCLUSION The Allergan Skin Roughness Scale is a validated and reliable scale for physician rating of midface skin roughness.

Abstract
The present work attempts to develop and statistically optimize transfersomes containing EGCG and hyaluronic acid to synergize the UV radiation-protective ability of both compounds, along with imparting antioxidant and anti-aging effects. Transfersomes were prepared by thin film hydration technique, using soy phosphatidylcholine and sodium cholate, combined with high-pressure homogenization. They were characterized with respect to size, polydispersity index, zeta potential, morphology, entrapment efficiency, Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), in vitro antioxidant activity and ex vivo skin permeation studies. Cell viability, lipid peroxidation, intracellular ROS levels and expression of MMPs (2 and 9) were determined in human keratinocyte cell lines (HaCaT). The composition of the transfersomes was statistically optimized by Design of Experiments using Box–Behnken design with four factors at three levels. The optimized transfersome formulation showed vesicle size, polydispersity index and zeta potential of 101.2 ± 6.0 nm, 0.245 ± 0.069 and −44.8 ± 5.24 mV, respectively. FTIR and DSC showed no interaction between EGCG and the selected excipients. XRD results revealed no form conversion of EGCG in its transfersomal form. The optimized transfersomes were found to increase the cell viability and reduce the lipid peroxidation, intracellular ROS and expression of MMPs in HaCaT cells. The optimized transfersomal formulation of EGCG and HA exhibited considerably higher skin permeation and deposition of EGCG than that observed with plain EGCG. The results underline the potential application of the developed transfersomes in sunscreen cream/lotions for improvement of UV radiation-protection along with deriving antioxidant and anti-aging effects.

Abstract
BACKGROUND A validated scale is needed for objective and reproducible comparisons of facial fine lines before and after treatment in practice and clinical studies. OBJECTIVE To describe the development and validation of the 5-point photonumeric Allergan Fine Lines Scale. METHODS The Allergan Fine Lines Scale was developed to include an assessment guide, verbal descriptors, morphed images, and real subject images for each scale grade. The clinical significance of a 1-point score difference was evaluated in a review of multiple image pairs representing varying differences in severity. Interrater and intrarater reliability was evaluated in a live subject validation study (N = 289) completed during 2 sessions occurring 3 weeks apart. RESULTS A score difference of ≥1 point was shown to reflect a clinically significant difference (mean [95% CI] absolute score difference, 1.06 [0.92-1.21] for clinically different image pairs and 0.50 [0.38-0.61] for not clinically different pairs). Intrarater agreement between the 2 live subject validation sessions was almost perfect (weighted kappa = 0.85). Interrater agreement was substantial during the second rating session (0.76, primary end point). CONCLUSION The Allergan Fine Lines Scale is a validated and reliable scale for physician rating of severity of superficial fine lines.

Abstract
Mesotherapy/biorevitalization with hyaluronic acid (HA) is a treatment approach currently used for skin rejuvenation. Various products with a wide range of polycomponent formulations are available on the market. Most of these formulations contain noncross-linked HA in combination with a biorevitalization cocktail, formed by various amounts of vitamins, minerals, amino acids, nucleotides, coenzymes, and antioxidants. Although ingredients are very similar among the different products, in vitro and clinical effects may vary substantially. There is a real need for better characterization of these products in terms of their action on human skin or in vitro skin models. In this study, we analyzed the effect of the RRS® (Repairs, Refills, Stimulates) HA injectable medical device on human skin fibroblasts in vitro. Skin fibroblast viability and its capacity to induce the production of key extracellular matrix were evaluated in the presence of different concentrations of RRS HA injectable. Viability was evaluated through colorimetric MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay, and key extracellular matrix genes, type I collagen and elastin, were quantified by quantitative polymerase chain reaction. Results demonstrated that RRS HA injectable could promote human skin fibroblast viability (+15%) and increase fibroblast gene expression of type I collagen and elastin by 9.7-fold and 14-fold in vitro, respectively. These results demonstrate that mesotherapy/biorevitalization products can, at least in vitro, effectively modulate human skin fibroblasts.
