RESUMO

BACKGROUND: A face-lift or rhytidectomy is the procedure most directly associated with rejuvenation. There are several surgical techniques for face-lifts, but criteria for the selection of techniques, based on the patient's face shape, are lacking. In this study, we report on our experience with specific indication criteria for each technique and the consequent achievement of good outcomes. METHODS: From 2015 to 2023, 1 surgeon performed face-lifts on 1000 patients. Three different superficial musculoaponeurotic system (SMAS) techniques (SMAS dissection, SMASectomy, and SMAS plication) were applied depending on the degree of sagging of the patient's lower face, lateral facial profile, and SMAS mobility and condition. Superficial musculoaponeurotic system dissection was considered for the improvement of a square face, sagging jowls, and marionette lines. Superficial musculoaponeurotic system plication was applied with patients with less sagging jowls and prominent zygoma with concave lateral facial profile. SMASectomy was applied with patients with convex lateral facial profiles or when the SMAS was too thin or damaged. Patient postoperative satisfaction was surveyed using the FACE-Q score 1 year post surgery. RESULTS: Most of the patients attained natural-looking and long-lasting aesthetic outcomes and exhibited high satisfaction. The patients indicated that they looked about 11.2 ± 5.2 years younger than their actual age after the surgery. The mean satisfaction scores for each facial feature were as follows: cheeks (91.1 ± 7.8), marionette lines (88.5 ± 13.6), lower face and jawline (92.5 ± 14.2), under chin (87.8 ± 15.1), and neck (86.2 ± 18.5). Complications such as facial nerve injury, infection, hematoma, and flap necrosis were very rare. CONCLUSIONS: Establishing criteria for the selection of face-lift surgical techniques based on the degree of lower face sagging, lateral facial profile, and SMAS mobility and condition led to good outcomes. These criteria can be used by physicians to determine the most effective face-lift surgery technique based on a patient's individual features, which may improve surgical outcomes.

RESUMO

DNA methylation (DNAm) is one of the most reliable biomarkers of aging across mammalian tissues. While the age-dependent global loss of DNAm has been well characterized, DNAm gain is less characterized. Studies have demonstrated that CpGs which gain methylation with age are enriched in Polycomb Repressive Complex 2 (PRC2) targets. However, whole-genome examination of all PRC2 targets as well as determination of the pan-tissue or tissue-specific nature of these associations is lacking. Here, we show that low-methylated regions (LMRs) which are highly bound by PRC2 in embryonic stem cells (PRC2 LMRs) gain methylation with age in all examined somatic mitotic cells. We estimated that this epigenetic change represents around 90% of the age-dependent DNAm gain genome-wide. Therefore, we propose the "PRC2-AgeIndex," defined as the average DNAm in PRC2 LMRs, as a universal biomarker of cellular aging in somatic cells which can distinguish the effect of different anti-aging interventions.

RESUMO

Direct neck lift offers an excellent surgical technique for men seeking to rejuvenate the neck and avoid a full rhytidectomy. In this chapter, we provide an overview of direct submentoplasty techniques, as well as clinical pearls to consider in the preoperative, intraoperative, and postoperative periods. Different surgical incisions and resultant scars in the anterior neck are discussed and illustrated with figures. Given the degree of variation of submental fullness with which patients present, it is beneficial to be familiar with several different techniques to address the submental and submandibular areas.

RESUMO

Many different methods achieve male facial augmentation. Arranged from shorter- to longer-term results, these methods include filler, fat/tissue grafting, fat/tissue transposition, and alloplastic implants. This study solely reviews allografts, which provide the most predictable hard-tissue augmentation. An array of alloplasts will be discussed in this study including chin, cheek, mandibular angle, frontal, and temporal implants. The most common and severe complications will also be explored with preventative and treatment algorithms.

RESUMO

There are many developmental sexual dimorphisms of the human face, and thereby differences in aging based on sex. Sensitivity regarding the nature of the changes that are unique to the male face as well as understanding men's unique aesthetic goals will allow the skilled practitioner to tailor rejuvenating treatments accordingly. Fat grafting of the male face has not been extensively described but is an excellent tool for facial rejuvenation either as an adjunct or a stand-alone procedure. Each treatment area demands different techniques and special attention to avoid unintentional feminization.

RESUMO

In this article, the authors describe their preferred advanced deep-plane techniques and modifications that have universally improved outcomes and durability in both men and women. Performing a proper extended deep-plane facelift and neck lift avoids the need to camouflage scars and stigmata of lifts seen in superficial musculoaponeurotic system plication and other techniques. In the author's experience, vertical vector deep-plane surgery is more durable, natural, and less reliant on lipofilling and volume addition. The subtleties of examination and analysis, surgical technique, clinical outcomes, and gender-specific considerations in the reconstruction of gonial and cervicomental angles, deep planar volumetric reduction, facial volumetric change, limited skin delamination, and revision techniques are discussed.

RESUMO

The development of minimally invasive, non-surgical, and office-based procedures that have minimal downtime has stimulated an interest among men who may seek cosmetic treatments to increase competitiveness and appear youthful in the workplace. There has also been greater media attention on the male appearance and grooming along with increasing acceptance of cosmetic procedures within society. Achieving a successful cosmetic treatment in a male patient requires the physician to recognize the gender differences that exist. These include anatomy, skin aging, and skin biology, as well as behavioral patterns that exist in this population.

RESUMO

Senescence and epigenetic alterations are two important hallmarks of cellular aging. During aging, cells subjected to stress undergo many cycles of damage and repair before finally entering either apoptosis or senescence, a permanent state of cell cycle arrest. The first biomarkers of senescence to be identified were increased ß-galactosidase activity and induction of p16INK4a. Another feature of senescent cells is the senescence-associated secretory phenotype (SASP), a complex secretome containing more than 80 pro-inflammatory factors including metalloproteinases, growth factors, chemokines and cytokines. The secretome is regulated through a dynamic process involving a self-amplifying autocrine feedback loop and activation of the immune system. Senescent cells play positive and negative roles depending on the composition of their SASP and may participate in various processes including wound healing and tumour suppression, as well as cell regeneration, embryogenesis, tumorigenesis, inflammation and finally aging. The SASP is also a biomarker of age, biological aging and age-related diseases. Recent advances in anti-age research have shown that senescence can be now prevented or delayed by clearing the senescent cells or mitigating the effects of SASP factors, which can be achieved by a healthy lifestyle (exercise and diet), and senolytics and senomorphics, respectively. An alternative is tissue rejuvenation, which can be achieved by stimulating aged stem cells and reprogramming deprogrammed aged cells. These non-clinical findings will open up new avenues of clinical research into the development of treatments capable of preventing or treating age-related pathologies in humans.

RESUMO

Objective: This study aimed to evaluate physical skin changes and patients' subjective perception of treatment with photothermal bioactivated platelet-rich plasma (MCT Plasma) for hand rejuvenation. Background: Age-related changes in the dorsum of the hand include volume loss, dyschromia, and soft-tissue atrophy, which result in wrinkles and prominent deep structures. Methods: We conducted a prospective, single-center, randomized pilot study on 10 healthy female volunteers from 30 to 65 years with hand aging signs. Patients received two sessions of MCT Plasma on the treated hand and two sessions of standard platelet-rich plasma (PRP) on the control hand. Results were assessed through high-frequency ultrasonography, photographs, a patient satisfaction survey, patient perception of skin aspect, and patient perception of amelioration survey. Results: Ten women with a mean age of 57.5 years (standard deviation 10.5, range 31 - 67) were included, and seven (70%) completed the study. The treated hands' skin subepidermal low-echogenic band (SLEB) decreased from 20% to 60%, and 57.1% (n = 4) had better results than control. Twenty percent of patients were very satisfied with the results, 40% were satisfied, 40% were neutral, and none were unsatisfied or very unsatisfied. Patients perceived the skin of the treated hand (MCT Plasma) as "much better" (20%), "better" (60%), and "no changes" (20%) compared with the skin of the control hand (standard PRP). No treatment-related adverse events were reported during the study. Conclusions: Hands treated with MCT Plasma tended to have better outcomes in reducing SLEB compared with those treated with standard PRP. Patients were satisfied and the treatment was safe with no technical complications. However, further randomized controlled trials with larger sample sizes are mandatory to validate the extent of improvement provided by this device based on photothermal biomodulation.

RESUMO

There is a current lack of bibliometric analysis in facial bone aging and relevant fields. By providing clear and intuitive references, predictions, and guidance for future research, this study aims to fill the gap in the current field, summarize the related research, and guide the researchers' future work. Literature data were retrieved from the Web of Science Core Collection database. Results Analysis and Citation Report of Web of Science, and CiteSpace software were used to optimize the visualization results, including publication characteristics, disciplines, journals, literature, countries/regions, institutions, authors, research focuses, etc. A total of 277 publications were included after manual screening, and the overall trend of annual publications and citations was increasing. On the basis of the analysis, the characteristics of facial bone aging, aging of facial soft tissue, and facial rejuvenation have been the focuses of research in this field. As stem cell research advances and researchers, deepen their comprehension of facial bone aging, basic scientific research on facial bones has witnessed a growing trend.

RESUMO

BACKGROUND: Skin rejuvenation is a widely sought-after goal, prompting advancements in laser technology for noninvasive and effective treatments. Ablative lasers, in particular, have evolved to address diverse skin concerns, with fractional ablative lasers offering better-tolerated outcomes. The introduction of a novel ablative Thulium pulsed laser, based on Thulium-doped Yttrium aluminum Perovskite (Tm:YAP) crystal, delivers precise and controlled skin rejuvenation by allowing customization of ablative microcolumns. METHODS: A pilot in vivo study was conducted on the abdominal skin of a live female pig. Using the Laser Team Medical (LTM) prototype laser, treatments were administered with varying coagulation settings (minimal and maximum) and energies (32, 80, 120, and 160 mJ per microcolumn). Biopsies were harvested, fixed, and stained for subsequent analysis. The penetration depth and width of the microcolumns were evaluated. RESULTS: Low coagulation settings produced ablative microcolumns with thermal affected zones of 160 µm width, while high coagulation settings resulted in wider zones of 400-530 µm. The ablation cavities' width was estimated to be less than 100 µm in both settings. The novel 1940 nm pulsed laser demonstrated superior microcolumn properties, offering potential advantages such as shorter downtime and increased efficacy compared to existing fractional ablative lasers. CONCLUSION: This study presents encouraging preliminary results regarding the efficacy and safety of the first ablative 1940 nm pulsed laser. The results show ablative microcolumns thinner than the counterpart devices, showing the device safety and potential higher efficacy along with short downtime. The LTM novel ablative 1940 nm pulsed laser holds immense potential for enhancing skin rejuvenation treatments due to its superior microcolumns properties. The versatility of this laser can open new treatment procedures and may extend to different areas of dermatology.

RESUMO

Intense pulsed light has a growing body of research supporting its use in skin rejuvenation, dermatologic conditions, as well as ocular rosacea, dry eyes and meibomian gland dysfunction. This paper will start with the conception of one protocol for treating dry eyes, blepharitis and styes using broad band light, a version of intense pulsed light, and its evolution into a life-changing in-office procedure for many patients. The approach for optimizing the settings, considerations during the consultation, the procedure in detail, after treatment care, and potential complications to avoid are all explained. Periocular and facial rejuvenation treatment protocols are discussed as well. This should be a useful guide for clinicians looking to add intense pulsed light to their in-office treatment armamentarium to significantly improve the lives of their patients.

RESUMO

BACKGROUND: Specialized aesthetic skincare treatments are an important part of helping reduce facial signs of aging. AIMS: This article highlights real-world experience with a Macrocystis pyrifera ferment-containing skincare regimen comprising a cleansing foam, a serum, and a moisturizer with anti-aging, anti-inflammatory, anti-erythema, and healing properties for facial skin condition improvement. PATIENTS/METHODS: The real-world case (RWC) series presented highlights and the expert panel's clinical experience with the M. pyrifera ferment-containing skincare regimen used for 12 weeks to improve facial skin conditions. The panelists convened a meeting to discuss and select RWCs from their practice using the M. pyrifera ferment-containing skincare regimen. RESULTS: The RWC series showed that erythema and inflamed, easily irritated skin bother patients, even when it is mild. Reducing inflammation, erythema, and visible signs of facial aging and improving skin health contributed to patient satisfaction. CONCLUSION: The M. pyrifera ferment-containing skincare regimen comprising a cleansing foam, a serum, and a moisturizer is effective in decreasing the visible effects of inflammation and signs of aging while promoting healing by enhancing barrier resilience and recovery.
