The skin serves protective roles for internal organs and is responsible for maintaining homeostasis between the body and the environment. The outermost and most exposed part of the skin to environmental factors is the stratum corneum (SC). SC hydration and transepidermal water loss (TEWL) values provide information about the physiological state of the skin. Plant oils, owing to their chemical structure, possess moisturizing and protective functions. This study assessed the impact of a single application of drying oil (Rubus idaeus seed oil), semi-drying oil (Sesamum indicum seed oil), and nondrying oil (Cocos nucifera (coconut) oil) on specific skin characteristics in young, healthy women. Thirty-five female volunteers (age: 20.03 ± 1.69) participated in the study. Before commencing the investigation, a questionnaire survey on the subjective assessment of skin condition and a body composition test were conducted. Subsequently, each participant had three oils applied to nonoverlapping skin areas on the forearms. Skin characteristics were assessed before and 1 h after the oil application using specialized probes: a corneometer and a tewameter. An enhancement in skin hydration was evident after the application of each of the tested oils (p = 0.001). Raspberry oil demonstrated the most significant moisturizing effect, while coconut oil showed the weakest impact. Only raspberry seed oil (p = 0.012) resulted in a noteworthy decrease in TEWL. The initial skin condition did not correlate with the subjects’ body composition, and the improvement induced by the application of the oils was not dependent on body weight, body water content, or BMI (body mass index). The applied vegetable oils positively influence the level of SC hydration. Improvement in barrier function, as measured by TEWL, was observed only for raspberry seed oil.

Background: After significant weight loss, the abdominal skin can become permanently stretched, resulting in stretch marks, laxity, and thinning of the dermis. For many patients, surgical methods such as abdominoplasty are too risky due to the potential for complications, the lengthy recovery period, and the high cost. Objective: The purpose of this pilot study was to use microfocused ultrasound, calcium hydroxyapatite, and Incobotulinum toxin A to improve the appearance of patients who were suffering from abdominal skin laxity after heavy weight loss. The combination of these treatments can provide comprehensive results with minimal downtime and lower risk compared to traditional surgical procedures. Methods: Our team treated four female Chinese patients with microfocused ultrasound, diluted calcium hydroxylapatite, and Incobotulinum toxin A with different combinations, respectively. The first and second cases were only treated with 810 shots of microfocused ultrasound. The third case received 850 shots of microfocused ultrasound plus 5 mL of diluted calcium hydroxylapatite and 50 units of Incobotulinum toxin A on the left abdominal skin, and the fourth case was treated with 900 shots of microfocused ultrasound plus 5 mL of diluted calcium hydroxylapatite and 10 units of Incobotulinum toxin A on the left abdominal skin. All four patients received a single treatment session. Clinical photographs were taken before each treatment, and two individual blinded investigators were asked to assess photographs taken after 4 weeks and compare them with the pretreatment photos. Results: All four cases showed an overall clinical improvement, with the third and fourth cases demonstrating more significant skin tightening based on photographic analysis. The data indicate that the inclusion of calcium hydroxylapatite and Incobotulinum toxin A in microfocused ultrasound treatment yields superior results for abdominal rejuvenation. Conclusions: Abdominal skin laxity can be treated with a triple therapy combining microfocused ultrasound, diluted calcium hydroxylapatite, and Incobotulinum toxin A.
背景：体重大幅下降后，腹部皮肤会永久性拉伸，导致妊娠纹、松弛和真皮变薄。对许多患者来说，腹部整形等手术方法风险太大，因为可能出现并发症、恢复期长且费用高昂。研究目的本试验性研究的目的是使用微聚焦超声波、羟基磷灰石钙和 A 型肉毒杆菌毒素来改善重度减肥后腹部皮肤松弛患者的外观。与传统的外科手术相比，这些治疗方法的组合能在最少的停工期和较低的风险下提供全面的效果。治疗方法我们的团队对四名中国女性患者分别进行了微聚焦超声波、稀释羟基磷灰石钙和 A 型肉毒杆菌毒素的不同组合治疗。第一例和第二例只接受了 810 针微聚焦超声波治疗。第三例患者接受了 850 次微焦超声波治疗，外加 5 毫升稀释的羟基磷灰石钙和 50 单位的 A 型伊可丁毒素（Incobotulinum toxin A）涂抹在左腹部皮肤上；第四例患者接受了 900 次微焦超声波治疗，外加 5 毫升稀释的羟基磷灰石钙和 10 单位的 A 型伊可丁毒素涂抹在左腹部皮肤上。所有四名患者均接受了一次治疗。每次治疗前均拍摄临床照片，并要求两名独立的盲人调查员对 4 周后拍摄的照片进行评估，并与治疗前的照片进行比较。结果：所有四个病例都显示出整体临床改善，根据照片分析，第三和第四个病例的皮肤紧致效果更为显著。数据表明，在微聚焦超声波治疗中加入羟基磷灰石钙和 A 型肉毒杆菌毒素，能产生更佳的腹部年轻化效果。结论：腹部皮肤松弛可通过微聚焦超声波、稀释的羟基磷灰石钙和A型伊可塑毒素三合一疗法进行治疗。

Skin disease is a severe health issue that affects a lot of people in Africa and is vastly underreported. Because of their availability, affordability, and safety, medicinal plants represent a major source of treatment for various skin diseases in West Africa. This review presents the medicinal plants used in treating skin diseases in West Africa and their available biological activities that have lent credence to their skin care usage. A total of 211 plant species from 56 families are implicated to be used in West Africa for several skin conditions such as aphthous ulcers, burns, eczema, scabies, sores, and wounds. Fabaceae is the most-implicated family (30 species) for the treatment of skin diseases, followed by Combretaceae (14 species) and Asteraceae (13 species). Most of the medicinal plants used are trees (93); leaves (107) were the most-used plant part, and decoction (73) was the preferred preparation method for the medicinal plants. The biological activities related to the pathology of skin diseases, such as antimicrobial and anti-inflammatory properties of 82 plants, have been evaluated. Based on their minimum inhibitory concentration, the most active antimicrobial plant is Brillantaisia lamium. Among the isolated phytochemicals, betulenic acid and lespedin were the most active, while plants such as Kigelia africana and Strophanthus hispidus showed significant wound-healing activities. This review highlights research gaps in the ethnobotanical studies of many West African countries, the biological activities of plants used to treat skin diseases, and the cosmetic potential of these plants.

Skin squamous cell carcinoma (SCC) represents a major public health concern due to its high incidence and potential for local invasion and metastasis. Compared to local recurrence, metastatic SCC represents an even greater therapeutic challenge. Once distant metastasis occurs, the disease becomes incurable, and treatment focuses on palliation and prolonging survival. The immune microenvironment of SCC is characterized by an infiltration of immune cells, including tumor-infiltrating lymphocytes. In addition to its direct cytotoxic effects, radiotherapy also induces immunomodulatory effects within the tumor microenvironment. Radiation can promote the release of tumor-associated antigens and induce immunogenic cell death, thereby enhancing the recognition of tumor cells by the immune system. Immunotherapy and radiotherapy have emerged as promising therapeutic modalities for metastatic SCC. This literature review aims to evaluate the potential synergy between these treatments and shed light on their combined efficacy. Within the manuscript, we present a compelling case report of a patient with advanced SCC who exhibited resistance to the combined regimen of immunotherapy and radiotherapy, leading to disease progression. Despite the increasing evidence supporting the synergy between these modalities, this case underscores the complex nature of treatment response and the importance of considering individual patient characteristics.

Pachyrhizus erosus (L.) Urb. is a tropical perennial vine plant native to southern Mexico, Southeast Asia, Central America, and Africa. In this study, we analyzed and identified various polyphenolic compounds and isoflavones present in ethanolic P. erosus root extracts and investigated their potential anti-obesity activity as a natural health food resource. The extraction process involved drying the yam bean, followed by extraction with 70% ethanol, evaporation, and freeze-drying. Fractionation was achieved through layer separation using n-hexane, ethyl acetate (EtOAc), butanol (BuOH), and water. The EtOAc fraction exhibited the highest antioxidant activity among the experimental groups, with an IC50 value of 531.77 µg/mL for ABTS radical scavenging. In α-glucosidase and lipase inhibition assays, IC50 values were determined to be 873.07 µg/mL and 915.02 µg/mL, respectively. Using HPLC and LC-MS/MS, we detected isoflavone components in P. erosus root extracts, identifying daidzein, genistein, and rotenone among them. Daidzein was the most abundant isoflavone in P. erosus root extracts. To validate the anti-obesity activity in the EtOAc fraction and daidzein, we used 3T3-L1 preadipocytes treated with MDI (3-isobutyl-1-methylxanthine, dexamethasone, insulin) for 8 days. Oil Red O staining experiments demonstrated a concentration-dependent reduction in lipid content in the EtOAc fraction and daidzein treatment groups. Additionally, we examined the expression pattern of proteins related to the leptin-PPAR-FAS Pathway, revealing a concentration-dependent decrease in obesity-related proteins.

The research was carried out on a hair conditioner containing the following rice derivatives individually: rice germ oil, rice germ oil GX-N, and riceterol esters. To evaluate the protective efficacy of the three active ingredients chosen, the following techniques were used: FT-IR, SEM, stress–strain test, and polarized light microscopy analysis. The tests were carried out on natural Caucasian hair. The methodologies were found to be suitable for the evaluation and led to interesting results: the selected ingredients showed good properties in improving the hair. The conditioners containing the active ingredients restored the properties of the hair even when subjected to stress such as irradiation. In this case, the most effective was the rice germ oil GX-N.

Bioactive peptides are promising cosmetic active ingredients that can improve skin health and appearance. They exhibit a broad spectrum of activity, including anti-aging, antioxidant, antimicrobial, and anti-inflammatory effects. The aim of this study was to develop a safe, stable, and efficacious environmentally friendly (“green”) emulsion using a milk protein hydrolysate as a model active ingredient. Potential emulsions were formulated with biodegradable emollients, stabilized with naturally derived mixed emulsifier, and prepared by cold process. They were evaluated for rheological behavior (continuous rotation and oscillation tests), physical stability (dynamic mechanical thermal analysis—DMTA test), and texture profiles, as well as cytotoxic, antioxidant, and antimicrobial effects. Rheological characterization revealed shear-thinning flow behavior with yield point from continuous rotation tests and predominantly elastic character from oscillation (amplitude and frequency sweep) tests, with small structural change detected in the DMTA test. These results implied satisfactory rheological properties and good stability. Texture analysis revealed acceptable spreadability and substantivity of the emulsions. The protein hydrolysate showed antioxidant activity. The developed emulsions showed low antibacterial activity against selected microorganisms, but this was due to the action of preservatives, not peptides. All potential emulsions showed a desirable safety profile. The results obtained provide the basis for the next stage of formulation development, i.e., in vivo efficacy tests.

In this study, we discovered that washing hair with surfactants causes a decrease in the internal density of hair, and we propose a cuticle-sealing strategy to inhibit this phenomenon. This phenomenon was revealed based on optical analyses such as optical microscopy, scanning electron microscopy (SEM), drop shape analysis, atomic force microscopy (AFM), and single hair analysis. Repeated treatment with surfactants creates areas of low density within the hair. Additionally, treatment with low-molecular-weight materials resulted in replenishment of the internal density of the hair. It has been shown that the more severe the degree of cuticle lifting, the more the internal density of the hair is reduced by surfactants. In addition, the study confirmed that a decrease in internal density could be prevented by sealing the cell membrane complex (CMC), and it was suggested that this reduced internal density may reflect the pore structure of hair. This study investigates the mass transfer phenomenon that occurs in hair and proposes a strategy to maintain hair homeostasis.

Repeated treatment with surfactants creates areas of low density within the hair. Additionally, treatment with low-molecular-weight materials resulted in replenishment of the internal density of the hair. It has been shown that the more severe the degree of cuticle lifting, the more the internal density of the hair is reduced by surfactants. In addition, the study confirmed that a decrease in internal density could be prevented by sealing the cell membrane complex (CMC), and it was suggested that this reduced internal density may reflect the pore structure of hair. This study investigates the mass transfer phenomenon that occurs in hair and proposes a strategy to maintain hair homeostasis.","PeriodicalId":10735,"journal":{"name":"Cosmetics","volume":"44 6","pages":""},"PeriodicalIF":3.3,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139228905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endocrine disruptors (EDs) are molecules capable of mimicking the natural hormones of the body and interfering with the endocrine system in both humans and wildlife. Cosmetic products are one source of EDs; these include an extensive variety of personal care and beauty products designed for the skin and hair, as well as makeup. The widespread use of such products has raised concerns about the presence of EDs within them. In this study, we highlight the issue of EDs and analyze the functioning of the EU regulatory framework for chemicals, specifically those which act as EDs in cosmetic products. We also highlight issues related to the interface between science and policy in the critical area of risk regulation within the EU. In addition, we investigate how chemical substances that act as EDs are identified based on specific criteria and conditions, a process which involves the production and adoption of particular scientific opinions. Finally, we assess the efficiency, suitability, and effectiveness of the regulatory framework in this sensitive area of human exposure to chemicals, especially those that function as EDs.
内分泌干扰物 (ED) 是能够模仿人体天然荷尔蒙并干扰人类和野生动物内分泌系统的分子。化妆品是 EDs 的一个来源；这些产品包括种类繁多的用于皮肤和头发的个人护理和美容产品以及化妆品。这类产品的广泛使用引起了人们对其中是否含有 ED 的关注。在本研究中，我们重点讨论了 ED 问题，并分析了欧盟化学品监管框架的运作情况，特别是化妆品中作为 ED 的化学品。我们还强调了欧盟在风险监管这一关键领域中科学与政策之间的衔接问题。此外，我们还研究了如何根据特定标准和条件来识别作为 ED 的化学物质，这一过程涉及特定科学意见的产生和采纳。最后，我们评估了在人类接触化学品（尤其是作为 EDs 的化学品）这一敏感领域的监管框架的效率、适宜性和有效性。

Interest in clean beauty is rising due to minimalism in the formulation of cosmetics, rational use of water, and fewer chemical additives like preservatives, colorants, surfactants, and artificial fragrances. Green ingredients lead to the development of sustainable formulations with advanced performance and are less aggressive to human health and the environment. Currently, the electrospinning technique is used as a simple one-step manufacturing process to produce nanostructured cosmetics under mild temperature conditions. This study focuses on the utilization of rice bran oil (RBO) in the creation of sustainable nanostructured cosmetics for potential cosmetic and well-being applications. Four sustainable formulations were developed to optimize the creation of nanostructured cosmetics using ethyl cellulose and rice bran oil (RBO). Ethanol absolute and polyvinyl pyrrolidone have been chosen to compose the sustainable formulation due to their biocompatibility and biodegradability. We studied four different RBO concentrations regarding morphology, encapsulation efficiency, biodegradability, and cytotoxicity. Nanostructured cosmetics present biomimetic surfaces, high RBO encapsulation ability, low mass loss at simulated physiologic conditions, and non-cytotoxicity. Therefore, the minimalist sustainable formulation does not contain any toxic solvents and incompatible harmful excipients, was nanostructured using a mild manufacturing process, and obtained high RBO entrapment.
