Looking for the philosopher's stone: Emerging approaches to target the hallmarks of aging in the skin.

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.

Vitamin A resolves lineage plasticity to orchestrate stem cell lineage choices.

Lineage plasticity-a state of dual fate expression-is required to release stem cells from their niche constraints and redirect them to tissue compartments where they are most needed. In this work, we found that without resolving lineage plasticity, skin stem cells cannot effectively generate each lineage in vitro nor regrow hair and repair wounded epidermis in vivo. A small-molecule screen unearthed retinoic acid as a critical regulator. Combining high-throughput approaches, cell culture, and in vivo mouse genetics, we dissected its roles in tissue regeneration. We found that retinoic acid is made locally in hair follicle stem cell niches, where its levels determine identity and usage. Our findings have therapeutic implications for hair growth as well as chronic wounds and cancers, where lineage plasticity is unresolved.

Rejuvenecimiento periorbitario fisiológico / Physiological periorbital rejuvenation

Pivoting Brow Lift es una nueva opción terapéutica cuyas ventajas son tres mínimas incisiones, prácticamente imperceptibles, bien aceptadas por pacientes de todas las edades, sexo y incluso pacientes calvos. Una incisión se realiza en la región temporal y otra dentro del cuero cabelludo en la región medio frontal o en una arruga en pacientes calvos. La disección en región frontal es sub-perióstica, muchas veces llega a la punta nasal para reposicionarla. La disección en la región temporal se realiza entre las hojas superficiales y profundas extendiéndose hasta el tarso y canto externo del ojo; en la región palpebral la disección se realiza entre la piel y el musculo. La fijación son dos puntos externos en el cuero cabelludo y unos papeles adherentes. Los puntos del cuero cabelludo se retiran a los 14 días. Evita las complejas fijaciones que se realizan actualmente con tornillos, puntos internos o Endotime. La sencillez del procedimiento hace que este se pueda realizar entre 30 y 45 minutos, con anestesia local y sedación; esto permite lograr una mayor seguridad operatoria. Se han documentado pacientes tratados hace 9 años donde se demuestra la duración en el tiempo. El bajo índice de complicaciones y la alta satisfacción de los pacientes documentadas en encuestas hace que este procedimiento pueda ser considerado como una nueva opción terapéutica.

Combining High-Density Fat and Condensed Low-Density Fat Injections for Precise Facial Rejuvenation.

BACKGROUND: Facial aging involves ptosis, adipose atrophy, and skeletal resorption. Depletion of adipose tissue primarily affects the deep facial fat compartment, leading to facial depression or ptosis, accompanied by atrophy of the superficial compartment. Restoring volume in the deep fat compartment is crucial for facial rejuvenation, while enhancing its supportive properties is also important. The superficial fat compartment contains small-sized adipocytes, and autologous fat grafting is a popular approach. However, variability in fat retention, homogeneity, and processing methods can impact outcomes, necessitating careful selection of a suitable fat processing material for precise facial fat grafting. METHOD: A retrospective study was conducted on 50 patients who underwent facial augmentation using combined transplantation of high-density fat (HDF) and condensed low-density fat (CLDF) and 25 patients who underwent conventional Coleman fat grafting. Coleman fat was harvested by standard technique and the adipose tissue was divided into HDF and CLDF fractions through centrifugation. Subsequently, the low-density fat fraction was subjected to a process involving physical disruption followed by additional centrifugation to obtain CLDF. The CLDF fraction was consequently injected into the pre-SMAS subcutaneous layer of the superficial fat compartments. Patient satisfaction was evaluated using a typical Likert scale. Photographs were taken and imageological examinations were performed before and after treatment. RESULT: The CLDF+HDF grafting group demonstrated a significantly shorter duration of swelling (6.0 ± 1.2 to 12.6 ± 3.3 days) and higher level of patient satisfaction when compared to the Coleman fat group. No serious complications were observed among all the patients who received the injections. CONCLUSION: The use of this new treatment approach allows for precise fat transplantation in facial regions. The use of high-concentration fat filling for deep facial layers and CLDF filling for superficial layers is a safe and effective treatment plan for facial rejuvenation.

Multi-omics characterization of partial chemical reprogramming reveals evidence of cell rejuvenation.

Partial reprogramming by cyclic short-term expression of Yamanaka factors holds promise for shifting cells to younger states and consequently delaying the onset of many diseases of aging. However, the delivery of transgenes and potential risk of teratoma formation present challenges for in vivo applications. Recent advances include the use of cocktails of compounds to reprogram somatic cells, but the characteristics and mechanisms of partial cellular reprogramming by chemicals remain unclear. Here, we report a multi-omics characterization of partial chemical reprogramming in fibroblasts from young and aged mice. We measured the effects of partial chemical reprogramming on the epigenome, transcriptome, proteome, phosphoproteome, and metabolome. At the transcriptome, proteome, and phosphoproteome levels, we saw widescale changes induced by this treatment, with the most notable signature being an upregulation of mitochondrial oxidative phosphorylation. Furthermore, at the metabolome level, we observed a reduction in the accumulation of aging-related metabolites. Using both transcriptomic and epigenetic clock-based analyses, we show that partial chemical reprogramming reduces the biological age of mouse fibroblasts. We demonstrate that these changes have functional impacts, as evidenced by changes in cellular respiration and mitochondrial membrane potential. Taken together, these results illuminate the potential for chemical reprogramming reagents to rejuvenate aged biological systems and warrant further investigation into adapting these approaches for in vivo age reversal.

Rejuvenation in Men Facial Aging: A Combined Approach.

Facelift surgery, also known as rhytidectomy, is a popular cosmetic procedure aimed at reversing the signs of facial aging. While facelift surgery is more commonly performed in women, an increasing number of men are seeking this procedure to maintain a youthful appearance. The long recovery period conflicts the overall primary outcome anticipated by men undergoing rhytidectomy, i.e., appear younger, youthful, and ready to reaffirm their value in the working environment. Anterior direct neck lift, blepharoplasty (upper and lower eyelid blepharoplasty), and lipofilling are three techniques that have been shown to be effective in improving facial rejuvenation outcomes in elderly male patients. However, there is little to no evidence of the safety and efficacy of these techniques when used in combination. By combining these techniques, we hypothesized that we could achieve outcomes comparable to traditional facelift surgery, but with a lower risk of complications and a shorter recovery time. We conducted a retrospective case series study of 18 male patients who underwent facial rejuvenation surgery using the combination of anterior direct neck lift, blepharoplasty (upper and lower eyelid blepharoplasty), and lipofilling at our institution between 2018 and 2021. All 18 patients completed the study, with an average follow-up of 12 months. No major complications were observed, and all patients reported a high level of satisfaction with their outcomes.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Platelet-Rich Plasma Versus Platelet-Poor Plasma for Treating Facial Photoaging: a Double-Blind Randomized Controlled Splitting Face Study.

BACKGROUND: As the demand for non-invasive esthetic procedures to maintain a youthful appearance increases, there has been growing interest in the use of autologous platelet-rich plasma (PRP) and platelet-poor plasma (PPP) for the treatment of facial aging. However, there are few studies directly comparing the efficacy of PRP and PPP for facial rejuvenation. OBJECTIVES: This study aimed to compare the efficacy of PRP and PPP for facial rejuvenation. METHODS: This single-center, double-blind, randomized controlled trial was conducted from January 1, 2022, to July 31, 2022, and included ten participants who completed the follow-up. The participants were randomly assigned to receive 2.5-mL injections of PRP and PPP on different sides of the face in three sessions with 1-month intervals. The outcome was primarily determined by blinded photographic assessments and secondly by scores of the VISIA® system during the follow-up. RESULTS: Both PRP and PPP treatments resulted in significant improvement in the Global Aesthetic Improvement Scales and Modified Fitzpatrick Wrinkle Scale for periocular Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation wrinkles, with no significant difference between the two groups. However, no improvement was observed in the Wrinkle Severity Rating Scales for nasolabial folds in either the PRP- or PPP-treated groups. Furthermore, no severe adverse events were reported. CONCLUSIONS: Both PRP and PPP are effective in treating facial photoaging. PRP exhibited slightly superior efficacy in enhancing overall skin condition, while PPP was slightly more effective in improving shallow wrinkles. This study provides valuable evidence for the use of PRP and PPP in facial rejuvenation procedures.

Facelift: Assessment of Total Platysma Muscle Transection to Prevent the Recurrence of Platysmal Bands.

INTRODUCTION: Determining which facelift technique yields the most effective long-term rejuvenation results and ensures optimal stability over time remains a significant question in cosmetic surgery: Does the most invasive surgery lead to the best long-term outcomes? This study aims to evaluate the authors' approach using total platysma muscle transection to prevent platysma band recurrence, and to provide anatomical observations supporting and justifying their procedure. MATERIAL AND METHODS: A preliminary study in anatomical basic sciences was conducted to establish the rationale for our method. A prospective single-blind study was conducted, involving eighty patients seeking facial rejuvenation with platysmal band correction. They underwent face and neck-lift procedures with total platysma transection by the same surgeon between May 2013 and May 2016. Cosmetic outcomes were assessed using the Face and Neck-Lift Objective Photo-Numerical Assessment Scale. Scores by three blind evaluators before surgery, at 1 and 5 years postoperatively, were compared using a matched T Test (p < 0.05). RESULTS: The preliminary anatomical study revealed a consistent anastomotic system between the cervical branch of the facial nerve and the branches of the cervical plexus. Incomplete platysma section during a facelift might contribute to platysma band recurrence. The clinical study demonstrated satisfactory outcomes, with significant overall appearance improvement (p < 0.00001) and no platysma band recurrence. Complication rate was low. CONCLUSION: The authors' technique achieved satisfactory long-term results with minimal complications. However, due to the lengthy operating time and steep learning curve, it should be reserved for highly motivated patients.

Somatic mutation burden in relation to aging and functional life span: implications for cellular reprogramming and rejuvenation.

The accrual of somatic mutations has been implicated as causal factors in aging since the 1950s. However, the quantitative analysis of somatic mutations has posed a major challenge due to the random nature of de novo mutations in normal tissues, which has limited analysis to tumors and other clonal lineages. Advances in single-cell and single-molecule next-generation sequencing now allow to obtain, for the first time, detailed insights into the landscape of somatic mutations in different human tissues and cell types as a function of age under various conditions. Here, we will briefly recapitulate progress in somatic mutation analysis and discuss the possible relationship between somatic mutation burden with functional life span, with a focus on differences between germ cells, stem cells, and differentiated cells.

Surgical Management of Platysma Bands: A Narrative Review of Evolving Concepts and Changing Techniques for Neck Rejuvenation.

INTRODUCTION: Platysmal bands are an unappealing feature of the aging face. Incomplete understanding of anatomy and physiology of platysmal bands has led to a long period of flawed or incomplete treatment. This review aims to elucidate the correct study of platysmal bands along with the most recent surgical treatments. MATERIALS AND METHODS: To identify all articles related to the topic of surgical management of platysmal bands, an extensive search was performed on PubMed and Medline databases for all articles related to platysmal bands from 1990 to 2023. The articles were then reviewed by 2 independent reviewers, and all relevant articles were selected. The search was narrowed down to clinical trials and cohort studies. RESULTS: 6130 articles were identified, of which 21 articles matched the inclusion criteria and were selected for the study totaling 2331 patients. Different surgical procedures were mentioned. Assessment of results was mostly subjective and done by the surgeon. CONCLUSION: Composite platysma-skin flap repositioning as opposed to wide skin undermining with or without submental incisions is being gradually accepted as a valid approach, with closed platysma myotomy and platysma denervation emerging as effective less invasive surgical modalities. Nevertheless, merits of more extensive procedures involving wide skin undermining and anterior platysma plication must not be lightly forgotten.

Increased hyaluronan by naked mole-rat Has2 improves healthspan in mice.

Abundant high-molecular-mass hyaluronic acid (HMM-HA) contributes to cancer resistance and possibly to the longevity of the longest-lived rodent-the naked mole-rat1,2. To study whether the benefits of HMM-HA could be transferred to other animal species, we generated a transgenic mouse overexpressing naked mole-rat hyaluronic acid synthase 2 gene (nmrHas2). nmrHas2 mice showed an increase in hyaluronan levels in several tissues, and a lower incidence of spontaneous and induced cancer, extended lifespan and improved healthspan. The transcriptome signature of nmrHas2 mice shifted towards that of longer-lived species. The most notable change observed in nmrHas2 mice was attenuated inflammation across multiple tissues. HMM-HA reduced inflammation through several pathways, including a direct immunoregulatory effect on immune cells, protection from oxidative stress and improved gut barrier function during ageing. These beneficial effects were conferred by HMM-HA and were not specific to the nmrHas2 gene. These findings demonstrate that the longevity mechanism that evolved in the naked mole-rat can be exported to other species, and open new paths for using HMM-HA to improve lifespan and healthspan.

Microneedling-Associated Procedures to Enhance Facial Rejuvenation.

Microneedling, also referred to as percutaneous collagen induction therapy, uses small needles to create mechanical injury to the skin, stimulating the wound-healing cascade and new collagen formation. Compared with other skin resurfacing techniques, microneedling preserves the epidermis and is nonablative, therefore reducing inflammation, downtime, and risk of dyspigmentation. In addition to increasing collagen production in fibroblasts, microneedling also helps normalize cell function of keratinocytes and melanocytes and can be used to increase absorption of topical medications, growth factors, or deliver radiofrequency directly to the dermis. The benefits of microneedling, associated procedures, indications for use, technical considerations, and potential complications are discussed.

A Systematic Review and Meta-Analysis of the Clinical Efficacy and Patients' Satisfaction of Micro-focused Ultrasound (MFU) Treatment for Facial Rejuvenation and Tightening.

PURPOSE: Micro-focused ultrasound (MFU) is commonly used to improve facial relaxation and wrinkles. The objective of this study was to determine the efficacy of MFU for facial rejuvenation and patients' satisfaction with the treatment. METHOD: Articles published before December 2022 were retrieved using PubMed, Embase, Web of Science, and Cochrane Library databases. The retrieved literature was screened according to strict criteria, and the risk of bias of each study was assessed. RESULT: A total of 13 MFU studies for facial rejuvenation and tightening were included, involving 477 participants. Efficacy was assessed using the Global Aesthetic Improvement Scale (GAIS), and meta-analysis showed an overall response rate of 0.77 (95%CI: 0.58, 0.96) at 90 days after intervention and 0.69 (95%CI: 0.51, 0.87) at 180 days. 0.78 (95%CI: 0.61, 0.95) and 0.71 (95%CI: 0.54, 0.87) patients were satisfied and very satisfied overall at 90 days and 180 days, respectively. The pain score was on a 10-point scale, and the overall score was 3.10 (95%CI: 2.71, 3.94). There were no instances during treatment where patients could not tolerate pain. Sensitivity analysis showed that the results were robust. CONCLUSION: In conclusion, MFU is an effective way to treat facial rejuvenation and tightening. More large-sample, multicenter and randomized studies are needed to determine the optimal treatment parameters in the future.

Cellular rejuvenation: molecular mechanisms and potential therapeutic interventions for diseases.

The ageing process is a systemic decline from cellular dysfunction to organ degeneration, with more predisposition to deteriorated disorders. Rejuvenation refers to giving aged cells or organisms more youthful characteristics through various techniques, such as cellular reprogramming and epigenetic regulation. The great leaps in cellular rejuvenation prove that ageing is not a one-way street, and many rejuvenative interventions have emerged to delay and even reverse the ageing process. Defining the mechanism by which roadblocks and signaling inputs influence complex ageing programs is essential for understanding and developing rejuvenative strategies. Here, we discuss the intrinsic and extrinsic factors that counteract cell rejuvenation, and the targeted cells and core mechanisms involved in this process. Then, we critically summarize the latest advances in state-of-art strategies of cellular rejuvenation. Various rejuvenation methods also provide insights for treating specific ageing-related diseases, including cellular reprogramming, the removal of senescence cells (SCs) and suppression of senescence-associated secretory phenotype (SASP), metabolic manipulation, stem cells-associated therapy, dietary restriction, immune rejuvenation and heterochronic transplantation, etc. The potential applications of rejuvenation therapy also extend to cancer treatment. Finally, we analyze in detail the therapeutic opportunities and challenges of rejuvenation technology. Deciphering rejuvenation interventions will provide further insights into anti-ageing and ageing-related disease treatment in clinical settings.

Myomodulation with Facial Fillers: A Comprehensive Technical Guide and Retrospective Case Series.

BACKGROUND: Placement of fillers in close proximity to the mimetic or sphincter muscles of the face appears to enhance or suppress muscle action in a relatively predictable way. METHODS: From June 2016 to June 2021, patients who underwent the first author's technique of myomodulation with dermal fillers to address aesthetic concerns or to manage facial spasms or synkinesis were evaluated in a retrospective case series. Additionally, the authors provide a technical guide for a whole-face approach to treatment with fillers and a conceptual map for treatment of each facial subunit with a focus on myomodulation. RESULTS: A total of 1352 patients (1108 women, 244 men; mean age, 51 years) underwent at least 1 treatment session during the 5-year study period. The treatment patterns of the study population and details of 2 representative cases are presented. CONCLUSIONS: Although not well understood mechanistically, myomodulation with injectable fillers shows promise for significant and reliable results of facial rejuvenation.

Noninvasive Vulvar and Intravaginal Treatments.

Radiofrequency is an effective and safe method for both pelvic floor restoration and nonsurgical labiaplasty. Bipolar radiofrequency with temperature control is more effective than monopolar radiofrequency for volumetric heating of vulvovaginal tissue. Combination of electrical muscle stimulation and radiofrequency can provide combined nonsurgical restoration of the vulvovaginal tissues.
