Bilateral Thermal Keratopathy Due to Plasma Skin Regeneration.

A 40-year-old woman underwent periocular plasma skin regeneration, a cosmetic treatment for periorbital rejuvenation. She subsequently developed bilateral thermal keratitis, manifesting as blurred vision, irritation, and redness, with a vision decrease to 20/60 and 20/50 in her OD and OS, respectively. Examination demonstrated bilateral large, irregular corneal epithelial defects and edema, necessitating treatment with amniotic membrane grafts, bandage contact lenses, and hypertonic saline. One year posttreatment, her visual acuity improved to 20/20 and 20/25, albeit with ongoing symptomatic dryness and bilateral anterior stromal haze. This case, as only the second reported instance of ocular damage from periocular plasma skin regeneration, underscores the need for heightened awareness of potential ocular complications following plasma skin regeneration and reinforces the importance of protective measures during periocular procedures.

Case Report: Primary Cutaneous Histoplasmosis in an Immunocompetent Patient After Cosmetic Injection of Platelet-Rich Plasma Treated with Trimethoprim-Sulfamethoxazole.

BACKGROUND Histoplasmosis is typically associated with immunocompromised individuals, but cases in immunocompetent patients are rare. Primary cutaneous histoplasmosis (PCH) is a challenging diagnosis due to its clinical polymorphism and can mimic other infectious and non-infectious diseases. Previous cases of PCH have been reported in immunocompetent patients with underlying medical conditions or trauma history. So far there have been no reports of PCH after platelet-rich plasma (PRP) application due to inadequate hygiene measures in an immunocompetent host. CASE REPORT This case report presents a rare occurrence of PCH following a cosmetic procedure (PRP injection) in an immunocompetent patient. The patient developed nodule-like lesions at the application sites, which progressed to ulceration with purulent discharge. Initially, atypical mycobacterial infection was suspected, and empirical antibiotic therapy was initiated. Complementary tests were performed, ruling out immunosuppression and systemic pathogens. The patient showed complete resolution of the lesions after one month of atypical treatment with trimethoprim-sulfamethoxazole (TMP/SMX). Pathological examination confirmed the diagnosis of PCH with intracytoplasmic inclusions of Histoplasma sp. CONCLUSIONS This case highlights the importance of considering histoplasmosis as a diagnostic possibility, especially in hyperendemic areas like Venezuela. Direct inoculation of Histoplasma sp. after aesthetic procedures without proper hygiene measures can lead to pathological lesions, even in immunocompetent individuals. TMP/SMX can be considered as an alternative treatment option in the absence of the first-line medication. Further exploration of this treatment approach may benefit patients with similar clinical conditions or when ideal treatment options are unavailable.

Why do marionette lines appear? Exploring the anatomical perspectives and role of thread-based interventions.

The pathogenesis of marionette lines involves a complex interplay of anatomical, physiological, and age-related factors leading to the development of wrinkles around the oral commissures. This exploration delves into the distinct anatomical predispositions observed among different ethnicities, emphasizing the role of compact modiolus structures and muscle compositions. Notably, individuals of East Asian descent exhibit inherent facial structures that predispose them to pronounced sagging around the oral commissures during aging. The emergence of distinct facial lines, such as the commissural line and the melolabial fold, contributes to the formation of marionette lines. This specific wrinkle pattern, resembling a marionette puppet's mouth contours, is influenced by various factors like bone resorption, gravitational forces, fat compartment variations, muscle compression, ligament tethering, and skin aging. Treatment strategies for marionette lines encompass diverse interventions, including filler injections, botulinum neurotoxin, surgeries targeting fat reduction, thread lifting, and volumizing fillers. These approaches aim to address the underlying causes and mitigate the appearance of marionette lines. Botulinum neurotoxin injections, for instance, weaken specific facial muscles, reducing downward strain and aiding in tissue retraction. Anatomical considerations during procedures are crucial to avoid nerve or vascular damage. Delicate manipulation and precise entry points are essential to prevent inadvertent injuries, particularly concerning blood vessels like the facial artery and nerves like the mental nerve. Technical guidelines for procedures targeting marionette lines involve specific techniques like cogged thread reverse methods and volumizing thread placements. Attention to entry points, tissue engagement, and the direction of threads is crucial for effective treatment outcomes, minimizing complications, and ensuring patient safety.

Molecular Insights Into the Effects of PLLA-SCA on Gene Expression and Collagen Synthesis in Human 3D Skin Models Containing Macrophages.

Injectable poly-L-lactic acid (PLLA-SCA) is used for the correction of shallow to deep nasolabial fold contour deficiencies, cheek wrinkles, and other facial wrinkles. In contrast to hyaluronan (HA) fillers, PLLA-SCA has a biostimulatory effect by activating resident fibroblasts to produce collagen, but the mechanisms are not known in detail at the molecular level. Therefore, our aim was to investigate the molecular effects of PLLA-SCA in a comprehensive in vitro study. Since PLLA-SCA-dependent collagen production in fibroblasts depends on the interaction with macrophages, we generated novel macrophage-containing 3D skin models. According to the clinical application, PLLA-SCA was injected once into the dermal equivalent of the 3D skin model. Histological analysis showed a significant increase in epidermal thickness in these models after 5 and 14 days. Gene expression profiling revealed an upregulation of integrins and laminins (e.g., LAMA3, ITGA6), which are essential components of the dermal-epidermal junction. In addition, we found an upregulation of cytokines and chemokines (TGFB2, CXCL6, IL1B) at day 14 after PLLA-SCA injection. Interestingly, immunohistochemical analyses exhibited a significantly stimulated collagen I production in our models. These effects might be attributed, at least in part, to the upregulation of IL1B and subsequently CXCL6, which stimulates collagen I synthesis in human dermal fibroblasts as we could demonstrate. Taken together, our data provide for the first time molecular insights into the biostimulatory effects of PLLA-SCA on collagen I production in novel human 3D skin models comprising macrophages.

Comparing the Safety and Effectiveness of Microfocused Ultrasound: Standard vs Targeted Tissue Protocol in Lifting and Tightening the Lower Face and Upper Neck.

BACKGROUND: Micro-focused ultrasound with visualization (MFU-V) delivers energy to specific soft tissue layers beneath the epidermis with the ability to lift and tighten the lower face and neck.  Objective: To determine the efficacy of microfocused ultrasound with visualization (MFU-V) using a standard treatment line protocol versus a customized treatment line protocol based on the patient's unique anatomy targeting the superficial muscular aponeurotic system and fibrous septae for lifting and tightening of the lower face and neck. METHODS: This was a single-center, prospective, randomized, investigator-blinded clinical trial. 51 subjects were randomized to receive a single treatment of MFU-V targeting the lower face and neck using either a standard or custom treatment protocol.   Results: Subjects in both standard and custom treatment groups noted a greater than one-point improvement in jawline laxity. Three-dimensional photography measurements also demonstrated lifting of the lower face and neck in both treatment groups. CONCLUSION: Custom and standard treatment MFU-V protocols produce a safe and effective treatment for tightening and lifting the lower face and neck. Custom treatment protocols aid in maximizing results for patients with variations in the anatomy of the lower face and neck.  J Drugs Dermatol. 2024;23(4):7647.     doi:10.36849/JDD.7647.

Effectiveness and Safety of a New Hyaluronic Acid Injectable for Augmentation and Correction of Chin Retrusion.

BACKGROUND: A hyaluronic acid (HA) filler intended for non-surgical improvement of chin appearance should ideally be of high strength/firmness (high G') to allow for deep injections on the bone. HASHA (Restylane Shaype) is a new hyaluronic acid (HA) injectable with high G' and high HA concentration (25 mg/mL), engineered by the new NASHA-HD (High Definition) technology. HASHA is suitable to be placed periosteally, aiming to mimic the natural shape of the bony chin. This pivotal clinical investigation evaluated effectiveness and safety of HASHA for augmentation and correction of chin retrusion.  Methods: Subjects 18 years or older with mild or moderate chin retrusion by the Galderma Chin Retrusion Scale (GCRS), were randomized 3:1 to HASHA (n=103) or no treatment (n=37). Assessments included GCRS (blinded evaluator), aesthetic improvement (Global Aesthetic Improvement Scale [GAIS]), subject satisfaction, and safety.  Results: GCRS responder rate (1-grade or greater improvement from baseline) was significantly higher for HASHA (83.3%) versus controls (10.8%) at month 3 (P<0.001) and maintained through month 12 (P<0.001). Aesthetic improvement was high throughout the study in the HASHA group, according to investigators (97% or greater) and subjects (89% or greater). Overall, subject satisfaction was high at month 3 and maintained at month 12. Product- or injection-related adverse events were mostly mild or moderate and transient. No product- or injection-related serious adverse events were reported. CONCLUSIONS: HASHA, a new NASHA-HD injectable with extra strength/firmness, was safe and effective for chin augmentation and correction of chin retrusion, with high aesthetic improvement and subject satisfaction throughout 12 months. J Drugs Dermatol. 2024;23(4):255-261.     doi:10.36849/JDD.8145.

Use of platelet rich plasma for skin rejuvenation.

OBJECTIVE: Platelet-rich plasma (PRP) is recognized as a safe and effective therapy for regenerative skin healing and rejuvenation, utilizing autologous blood enriched with various growth factors. This review aims to assess the efficacy of PRP treatments for skin rejuvenation. METHODS: Keywords such as "platelet-rich plasma," "rejuvenation," "skin aging," and "wrinkles" were queried on Ovid, PubMed, and MEDLINE to identify pertinent studies on PRP treatment for skin rejuvenation. RESULTS: Analysis revealed that PRP treatment led to significant enhancements in multiple facial parameters after one to three sessions. Improvements were noted in skin pore size, texture, wrinkle reduction, pigmented spots, collagen density, hyaluronic acid levels, and protection against ultraviolet damage. Combining PRP with hyaluronic acid demonstrated a synergistic effect, particularly enhancing skin elasticity in patients with lower body mass index and firmness in individuals aged 50s and 60s. Incorporating both physical and biometric data for assessment proved superior to relying solely on physical observations for evaluating subtle skin quality and structural changes. CONCLUSION: This study underscores the efficacy of PRP monotherapy for skin rejuvenation and emphasizes the necessity of standardizing PRP preparation protocols in future investigations. Heightened awareness and advancements in technology have contributed to the emergence of higher-quality, less biased studies supporting PRP as a reliable and safe therapeutic option for skin rejuvenation.

Aesthetic doctors' perception and attitudes toward tolerance in botulinum toxin.

BACKGROUND: Botulinum toxin is a crucial therapeutic tool with broad indications in both cosmetic and medical fields. However, the expanding cosmetic use and increased dosages of botulinum toxin have raised concerns about resistance, making it essential to study the awareness and management practices among healthcare professionals. METHODS: A survey was conducted among clinical physicians using botulinum toxin. The study investigated their experiences, awareness, and management practices related to toxin resistance. Real-time mobile app-based surveys were administered to clinicians attending the 45th International Academic Conference of the Korean Academy of Laser and Dermatology (KALDAT) on December 3, 2023. RESULTS: Among 3140 participants, 673 clinical physicians completed the survey. Of these, 363 clinicians (53.9%) reported experiencing botulinum toxin resistance. Regarding the resistance rate, 59.4% indicated less than 1%, 36% reported approximately 1%-25%, and 95.4% reported less than 25%. Efforts to prevent resistance included maintaining intervals of over 3 months (54.8%), using products with lower resistance potential (47.0%), employing minimal effective doses (28.2%), and minimizing re-administration (14.9%). CONCLUSION: In the South Korean aesthetic medicine community, a majority of clinical physician's report encountering botulinum toxin resistance. Given the potential loss of various benefits associated with resistance, there is a need to establish appropriate guidelines based on mechanistic studies and current status assessments. Educating clinicians on applicable guidelines is crucial.

Investigation of Presumptive HIV Transmission Associated with Receipt of Platelet-Rich Plasma Microneedling Facials at a Spa Among Former Spa Clients - New Mexico, 2018-2023.

HIV transmitted through cosmetic injection services via contaminated blood has not been previously documented. During summer 2018, the New Mexico Department of Health (NMDOH) was notified of a diagnosis of HIV infection in a woman with no known HIV risk factors who reported exposure to needles from cosmetic platelet-rich plasma microneedling facials (vampire facials) received at a spa in spring 2018. An investigation of the spa's services began in summer 2018, and NMDOH and CDC identified four former spa clients, and one sexual partner of a spa client, all of whom received HIV infection diagnoses during 2018-2023, despite low reported behavioral risks associated with HIV acquisition. Nucleotide sequence analysis revealed highly similar HIV strains among all cases. Although transmission of HIV via unsterile injection practices is a known risk, determining novel routes of HIV transmission among persons with no known HIV risk factors is important. This investigation identified an HIV cluster associated with receipt of cosmetic injection services at an unlicensed facility that did not follow recommended infection control procedures or maintain client records. Requiring adequate infection control practices and maintenance of client records at spa facilities offering cosmetic injection services can help prevent the transmission of HIV and other bloodborne pathogens and ensure adequate traceback and notification in the event of adverse clinical outcomes, respectively.

Understanding Public Awareness and Practices of Nonsurgical Facial Dermal Fillers: A Cross-Sectional Study in Saudi Arabia.

BACKGROUND: Dermal fillers augment soft tissues by replacing lost volume in the skin or subcutaneous fat. Dentists and other professionals utilize or recommend facial fillers for cosmetic and therapeutic purposes. AIMS: This study aims to investigate public awareness regarding using nonsurgical facial dermal fillers in Saudi Arabia. METHODS AND MATERIAL: A cross-sectional study was conducted using an online self-administered questionnaire distributed to a total of 400 males and females through social media platforms. The participants reside in Mecca, Saudi Arabia. Descriptive statistics and the Chi-square test were employed for data analysis. RESULTS: A total of 256 participants completed the survey, including 204 females and 51 males, with a mean age of 33.86 (SD = 10.5) years. Among the participants, 88 (34.4%) reported using facial fillers. Among them, only 46 (18%) were frequent consumers. Knowledge regarding correctly using facial fillers was generally high, especially for the lips (240, 94%), chin augmentation (203, 79.3%), and face lifting (226, 88.3%). However, participants' knowledge needed improvement in other areas. Most participants were aware of the side effects, except for visual impairment (83, 32.4%) and blockage of the vessels (128, 50%). CONCLUSIONS: The findings highlighted a remarkable level of knowledge among participants regarding the uses of fillers. However, participants demonstrated low awareness of all possible side effects associated with the treatment. Participants had valid reasons for undergoing facial treatments. However, constraints preventing them from pursuing fillers included fear of unexpected results and financial limitations.

Aesthetic Rehabilitation Medicine: Enhancing Wellbeing beyond Functional Recovery.

Although rehabilitation medicine emphasizes a holistic health approach, there is still a large gap of knowledge about potential interventions aimed at improving overall wellbeing through cosmetic interventions. Therefore, this narrative review investigates the role of different rehabilitative techniques in enhancing aesthetics, quality of life, and psychosocial wellbeing for patients with disabilities. The study follows the SANRA framework quality criteria for a narrative review. Literature searches across PubMed/Medline, Web of Science, and Scopus identified articles focusing on rehabilitation strategies within the aesthetic rehabilitation domain. The review identified evidence supporting injection procedures, such as Botulinum Toxin, Platelet-Rich Plasma, Hyaluronic Acid, Ozone, and Carboxytherapy, and assessing their applications in several disabling disorders. Additionally, physical therapies like Extracorporeal Shock Wave Therapy, Laser Therapy, Microcurrent Therapy, Tecar Therapy, and physical exercises were explored for their impact on cutaneous microcirculation, cellulite treatment, wound healing, and scar appearance improvement. Lastly, the manuscript underlines the role of manual therapy techniques in addressing both physical discomfort and aesthetic concerns, discussing their effectiveness in adipose tissue therapy, scar tissue mobilization, and regional fat thickness reduction. Taken together, this review emphasizes the role of a multidisciplinary approach, aiming to provide valuable insights into potential benefits for both functional and aesthetic outcomes.

Combined microfocused ultrasound and delicate pulsed light for facial rejuvenation: A prospective, randomized, and split-face study.

OBJECTIVES: Public's interest in noninvasive skin rejuvenation treatments continues to grow. The advantage of combination therapy lies in that it can target different aspects of skin rejuvenation. This study aimed to assess the efficacy and safety of microfocused ultrasound (MFU) combined with delicate pulsed light (DPL) for facial rejuvenation. METHODS: Twenty-one patients with facial relaxation were enrolled. All patients received whole-face MFU treatment, and one side of the face was randomly assigned to receive DPL. MFU treatment was performed at Months 0 and 3, while DPL treatment was performed at Months 1, 2, 4, and 5. The length and angle of the nasolabial fold and perioral wrinkles, melanin index (MI), erythema index (EI), transepidermal water loss (TEWL), and follow-up time were recorded at Months 0, 3, and 6. Side effects were recorded during treatment and each follow-up visit. RESULTS: Twenty patients successfully completed the study. At the sixth month, the average length of perioral wrinkles and nasolabial folds on the combined side decreased by 11.5% (pwithin < 0.001) and 6.5% (pwithin = 0.011), while 8.3% (pwithin = 0.012) and 3.8% (pwithin = 0.02) on the MFU side. Compared with MFU treatment alone, the combined treatment also showed significant improvements in nasolabial fold angle (from 28.8 ± 3.4° to 32.7 ± 5.0°) and perioral wrinkle angle (from 39.3 ± 5.0° to 43.7 ± 5.1°). In addition, the combined side had greater benefits than the MFU side in improving MI, EI, TEWL, and skin elasticity (pbetween < 0.05). Except for one patient who withdrew due to increased skin sensitivity after MFU treatment, other subjects did not experience permanent or serious side effects. CONCLUSIONS: The combination of MFU and DPL for facial rejuvenation treatment is safe and effective. The combined treatment has better efficacy in skin firmness, and improving skin tone.

Anatomy of the temporal region to guide filler injections.

Hollow temples are not typically considered aesthetically pleasing, and hollowness worsens with the aging process. When filling this region with fillers, there are several anatomical considerations, with injection techniques varying depending on the layer targeted. Specifically, injections between the superficial temporal fascia and the superficial layer of the deep temporal fascia are performed using a cannula, while periosteal layer injections involve the use of a needle to reach the bone before inserting fillers. Detailed anatomical insights encompass the boundaries of the temporal fossa and cautionary notes regarding blood vessels, supported by specific studies on veins and arteries in the temporal region. Complications, including vessel injuries, are discussed alongside an exploration of various injection techniques. This review provides a comprehensive exploration of anatomical considerations and the specific methodologies employed in temple augmentation with fillers.

The emerging role of biostimulators as an adjunct in facial rejuvenation: A systematic review.

INTRODUCTION: Facial aging has long been an area of focus in esthetic surgery. It is the consequence of physiologic and environmental factors, with a trend toward non-surgical modalities. Although volume augmentation has long been a focus of non-surgical facial rejuvenation, there is emerging interest in the use of biostimulators to induce physiologic changes in the skin. This article aimed to provide an overview of this class of therapies. METHODS: A systematic review regarding the clinical use of biostimulatory agents including platelet-rich plasma (PRP), platelet-rich fibrin (PRF), poly-L-lactic acid (PLLA) and calcium hydroxylapatite (CaHA) in facial rejuvenation was performed using PubMed databases. The protocol was developed following the preferred reporting for items for systematic reviews-protocols guidelines. Included studies matched predetermined criteria according to the employed intervention and outcomes. RESULTS: The systematic review was performed in September 2023, with the primary search yielding 464 articles. Abstract review resulted in 73 articles of potential relevance. Comprehensive review of the articles and manual reference checks were performed, independently, by 2 authors. This yielded a total of 45 articles that met the inclusion criteria. CONCLUSIONS: There is an increasing role for non-surgical modalities in facial rejuvenation. Biostimulatory agents may be used as an alternative, or act as an adjunct, to other non-surgical modalities. These agents induce physiologic changes that mitigate facial aging. There is limited, quantifiable data, which fully illustrate the effect in these products. Although these agents are known to illicit inflammatory changes, more controlled studies are needed to better elucidate the biostimulatory capacity of such non-surgical treatments.

Treatment with synchronized radiofrequency and facial muscle stimulation: Histologic analysis of human skin for changes in collagen and elastin fibers.

BACKGROUND: Skin's exposure to intrinsic and extrinsic factors causes age-related changes, leading to a lower amount of dermal collagen and elastin. AIM: This study investigated the effects of a novel facial muscle stimulation technology combined with radiofrequency (RF) heating on dermal collagen and elastin content for the treatment of facial wrinkles and skin laxity. METHODS: The active group subjects (N = 6) received four 20-min facial treatments with simultaneous RF and facial muscle stimulation, once weekly. The control subject (N = 1) was untreated. Skin biopsies obtained at baseline, 1-month and 3-month follow-up were evaluated histologically to determine collagen and elastin fibers content. A group of independent aestheticians evaluated facial skin appearance and wrinkle severity. Patient safety was followed. RESULTS: In the active group, collagen-occupied area reached 11.91 ± 1.80 × 106 µm2 (+25.32%, p < 0.05) and 12.35 ± 1.44 × 105 µm2 (+30.00%, p < 0.05) at 1-month and 3-month follow-up visits. Elastin-occupied area at 1-month and 3-month follow-up was 1.64 ± 0.14 × 105 µm2 (+67.23%, p < 0.05), and 1.99 ± 0.21 × 105 µm2 (+102.80%, p < 0.05). In the control group, there was no significant difference (p > 0.05) in collagen and elastin fibers. Active group wrinkle scores decreased from 5 (moderate, class II) to 3 (mild, class I). All subjects, except the control, improved in appearance posttreatment. No adverse events or side effects occurred. CONCLUSION: Decreased dermal collagen and elastin levels contributes to a gradual decline in skin elasticity, leading to facial wrinkles and unfirm skin. Study results showed noticeable improvement in facial appearance and increased dermal collagen and elastin content subsequent to simultaneous, noninvasive RF, and facial muscle stimulation treatments.

The role of the beautician in reducing striae.

INTRODUCTION: Striae distensae are a permanent skin defect that can affect 50%-90% of the population. The appearance of the changes resembles spindle-shaped skin bands. The skin in this area is wrinkled, thin and looks like a scar. Most often, the changes are found on the skin of the abdomen, buttocks, breasts, thighs, and back. The appearance of striae means that the skin in this area has no hair follicles, sebaceous, and sweat glands. This skin is flabby, not very elastic and, what is very characteristic, the pigmentation of the skin affected by striae is much lower than in healthy skin. Cosmetology in the 21st century is developing very dynamically, new technologies are being developed, new cosmetological devices are being created and combined with treatments that have been known for a long time. Today's science offers hope for people who have struggled with reducing striae for many years and nowadays, nothing is impossible. AIMS: The objective of this article is to provide information about cosmetological treatment used to reduce striae. METHODS: In this article, we reviewed the published literature, article published in peer-reviewed journals. RESULTS: Today's cosmetology offers a wide range of numerous treatments, but the best results are achieved through a synergy of two or more treatments. But we should not forget that we should respond to each customer individually. CONCLUSION: The striae are not a problem that should be ignored. The beauty therapist is able to reduce them and help the client to improve the appearance of their skin.
