(1) Background: Skin undergoes constant changes, providing capabilities to repair and renovate its constituents once damaged and a fundamental shield to contrast environmental stress. Nevertheless, environmental stressors may overcome the skin’s protective potential inducing premature aging and accelerating the appearance of anaesthetic age-related skin aspects. Ultraviolet radiation (UVR) and pollutants (particulate matters, PAHs) contribute to skin aging and functional decline inducing harmful oxidative modifications of macromolecules and stress-related skin disorders. Innovative approaches to preserve skin are needed. (2) Methods: Skin keratinocytes were treated (or not) with a combination of ingredients (Lactobacillus plantarum extract, Withania somnifera root extract and Terminalia ferdinandiana fruit extract; “MIX”) in the presence or absence of stress (oxidative stress or pollution). The effects of the MIX adaptogen technology on (a) cellular resilience, (b) the regulation of cellular functions and (c) regeneration of skin were disclosed through expression proteomics and bioinformatics analyses first, and then through focused evaluations of protein carbonylation as a hallmark of oxidative stress’ deleterious impact and mitochondrial activity. (3) Results: The deleterious impact of stressors was evidenced, as well as the beneficial effects of the MIX through (a) mitochondrial activity preservation, (b) the “vigilance” of the NRF2 pathway activation, (c) NADPH production and protein homeostasis improvements, (d) preserving skin regeneration function and I the contrasting stress-induced oxidation (carbonylation) of mitochondrial and nuclear proteins. (4) Conclusions: The effects of the MIX on increasing cell adaptability and resilience under stress suggested a beneficial contribution in precision cosmetics and healthy human skin by acting as an adaptogen, an innovative approach that may be employed to improve resistance to harmful stress with a potential favourable impact on skin homeostasis.

The practice of voluntary depigmentation is still prevalent in Africa, with a wide range of lightening cosmetics used. Our objective was to research and quantify three regulated and/or prohibited depigmenting ingredients present in lightening cosmetics sold in Ouagadougou. Twenty-nine lightening cosmetic samples were collected from vendors and HPLC analysis was subsequently conducted to identify and measure the concentrations of hydroquinone, clobetasol propionate, and kojic acid. The presence of hydroquinone was indicated on the label of 13.79% of the products, while 51.72% contained it after analysis. Furthermore, none of the products mentioned a concentration of hydroquinone exceeding 2.00%, even though 27.58% of them contained high concentrations. For clobetasol propionate, its presence was stated on the labels of 13.79% of the products, while 31.03% contained it. One sample had a clobetasol content exceeding 0.05%, although none mentioned a concentration higher than this value. Finally, while 24.13% of the samples claimed to contain kojic acid, only 17.24% did. We also observed that 41.38% of the samples contained combinations of two depigmenting ingredients investigated, with a predominance of the hydroquinone + clobetasol propionate (27.38%). These results demonstrate that manufacturers’ declarations regarding the compositions of active ingredients in lightening cosmetics can sometimes be deceptive.

Introduction: There are few long-term effectiveness and safety data for dupilumab in the treatment of atopic dermatitis (AD). The aim of this study was to evaluate efficacy and safety of dupilumab for up to three years after treatment initiation. Materials and Methods: We collected data from patients ≥ 12 years with severe AD who started dupilumab at the Dermatology Clinic of the Turin University Hospital between December 2018 and October 2022. Clinic and patient reported outcomes were evaluated from baseline, up to 3 years (T9), every 4 months. Results: A total of 418 patients were observed. A progressive decrease in the meanEASI was observed: from 23.64 at baseline to 2.31 at T9. Similar trends were observed in patients’ reported outcomes. The achievement of EASI75 and EASI90 was observed in 75.58% of patients and 53.49%, respectively, at T1 (4 months), and in 92.55% and 80.85% at T9; DLQI 0/1 was achieved at T9 in 61.7%. Mean NRSpp ≤ 4 was achieved at T9 in 91.5% (86 out of 94 patients). The most common adverse event was conjunctivitis occurring in 13% of patients on average at each timepoint analyzed. Conclusions: Dupilumab proved to be effective and safe for the treatment of AD in clinical practice, up to 3 years.

Black pepper, a commonly utilized culinary condiment, holds significant importance in Ayurvedic and Chinese medicinal practices due to its various biological benefits, including antioxidant, antimicrobial, and anti-inflammatory properties. To amplify these attributes and enhance their efficacy in formulations, the utilization of nanocarriers presents a promising approach. Thus, the objective of this study was to obtain a pepper extract, evaluate its constituents, and encapsulate it in polymeric nanoparticles. The ethanol extract of the grains powder had a higher concentration of piperine and better antioxidant activity when compared to whole grains. Pepper extract encapsulation efficiency in terms of piperine concentration was 84.8 ± 3.5%, and a sustained and prolonged release profile was observed, as well as other studies in the literature using polycaprolactone (PCL). The presence of the extract did not change the instability index and the sedimentation velocity of the nanoparticles, as well as the polydispersity index and the zeta potential of nanoparticles. However, there was a difference in the mean size and concentration of particles. This study highlights the potential of PCL nanoparticles as a promising delivery system for black pepper extract, which could have various applications in the cosmetic and pharmaceutical industries, maximizing the benefits of black pepper extract.

Skin aging and wrinkle formation are processes that are largely influenced by the overexpression of enzymes like tyrosinase, elastase, and collagenase. This study aimed to validate the skin anti-aging properties of phytochemicals from Peperomia pellucida (PP) as well as its attendant mechanism of action. Compounds previously characterized from PP were retrieved from the PubChem database and docked to the active sites of tyrosinase, elastase, and collagenase using Schrödinger’s Maestro 11.5 and AutoDock tools to predict compounds with the best inhibitory potential to block these enzymes in preventing skin aging. It was observed that our hit compounds had favorable affinity and displayed key interactions at the active sites of these enzymes similar to those of the standards. With elastase, we observed key interactions with the amino acids in the S1 sub-pocket (especially ALA-181), Zn chelation, and histidine residues, which are key for inhibitory activity and ligand stability. The hit compounds showed H-bonds with the key amino acids of collagenase, including LEU-185 and ALA-186; phlobaphene and patuloside B were found to have better docking scores and inhibition constants (Ki) (−12.36 Kcal/mol, 0.87 nM and −12.06 Kcal/mol, 1.45 nM, respectively) when compared with those of the synthetic reference compound (−12.00 Kcal/mol, 1.67 nM). For tyrosinase, our hit compounds had both better docking scores and Ki values than kojic acid, with patuloside B and procyanidin having the best values of −9.43 Kcal/mol, 121.40 nM and −9.32 Kcal/mol, 193.48 nM, respectively (kojic acid = −8.19 Kcal/mol, 898.03 nM). Based on this study, we propose that acacetin, procyanidin, phlobaphene, patulosides A and B, palmitic acid, and hexahydroxydiphenic acid are responsible for the anti-aging effects of PP on the skin, and that they work synergistically through a multi-target inhibition of these enzymes.

Silver nanoparticles (AgNPs) produced by biological methods are safer for biomedical applications. Melanins were initially reported to facilitate AgNPs synthesis. Our research found that the stromata of some Xylaria species contained significant amounts of melanins, which had strong antioxidant and anti-ultraviolet activities without toxicity toward human skin cells. This study reported the characteristics and antibacterial activities against skin-infecting bacteria (Staphylococcus aureus and Cutibacterium acnes) of AgNPs synthesized using crude melanin extracted from stromata of Xylaria sp. AgNPs were successfully synthesized by mixing the crude melanin solution with 0.1 M AgNO3 (25:1, v/v) and incubating for 3 h at 100 °C. The SEM found that the average size of the synthesized AgNPs was 18.85 ± 3.75 nm. The melanin-mediated AgNPs displayed significantly higher antibacterial activities against the tested acne-causing bacteria compared to the positive control (Erythromycin). Specifically, the melanin-mediated AgNPs inhibited 90% of S. aureus and C. acnes at 62.5 (µg/mL) and 15.625 (µg/mL), respectively, whereas it required erythromycin up to 4000 (µg/mL) to achieve the same activities. This research illustrated the feasibility of using crude melanin of Xylaria sp. for the direct synthesis of AgNPs and the potential use of the synthesized AgNPs for treating acne-causing bacteria (with further investigation needed).
生物方法生产的银纳米颗粒(AgNPs)在生物医学应用中更安全。黑色素最初被报道促进AgNPs的合成。我们的研究发现，一些木耳属植物的基质中含有大量的黑色素，具有较强的抗氧化和抗紫外线活性，对人体皮肤细胞无毒。本研究报道了从Xylaria sp.基质中提取的粗黑色素合成的AgNPs的特性及其对皮肤感染细菌(金黄色葡萄球菌和痤疮角质杆菌)的抗菌活性。将粗黑色素溶液与0.1 M AgNO3 (25:1, v/v)混合，在100℃下培养3 h，成功合成了AgNPs。SEM发现，合成的AgNPs的平均尺寸为18.85±3.75 nm。与阳性对照(红霉素)相比，黑色素介导的AgNPs对测试的痤疮引起的细菌显示出显着更高的抗菌活性。具体来说，黑色素介导的AgNPs分别在62.5(µg/mL)和15.625(µg/mL)时抑制90%的金黄色葡萄球菌和痤疮C.，而红霉素高达4000(µg/mL)才能达到相同的活性。本研究说明了利用Xylaria sp.的粗黑色素直接合成AgNPs的可行性，以及合成的AgNPs用于治疗引起痤疮的细菌的潜在用途(有待进一步研究)。

In Indonesia, plants have been indigenously used to treat various diseases and as cosmetics. It is always challenging to explore the molecular interactions of phenolic compounds towards the levels of constituents that contribute to the biological activities of plants. This study aimed to select a plant of the Zingiberaceae family with the highest phenolics and flavonoids, the strongest radical scavenging activity, and the best interaction towards tyrosinase in terms of docking score and binding mode. Initially, the total phenolics and radical scavenging capacity of Zingiberaceae plants, namely, Hedychium coronarium, Curcuma zedoaria, Curcuma heyneana, and Alpinia galanga, were determined using the Folin–Ciocâlteu method and the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The main phytoconstituents of plants with the highest phenolic levels were docked to the binding site of tyrosinase. Three anti-melanogenesis agents commonly used in cosmetics, namely, arbutin, hydroquinone, and kojic acid, were used as the standard. Our study revealed that all the tested plants contain polyphenolic compounds in the range of 17.92 (C. zedoaria rhizome extract) to 252.36 (A. galanga rhizome extract) mg GAE/g and have radical scavenging capacity, with IC50 values in the range of 66.67 (A. galanga rhizome extract) to 320.0 (C. heyneana rhizome extract) μg/mL. A molecular docking simulation demonstrated that four constituents, i.e., kaempferol, galangin, ethyl p-methoxycinnamate, and 6-gingerol, could occupy the binding site of tyrosinase with prominent affinity and interact with essential residues of the enzyme. This study confirms that Alpinia galanga possesses the potential to be further developed as a cosmetic with a radical scavenging and tyrosinase inhibitory activity. However, it may be interesting to carry out further studies of how the plant extract affects the melanogenesis signaling pathway.

However, it may be interesting to carry out further studies of how the plant extract affects the melanogenesis signaling pathway.","PeriodicalId":10735,"journal":{"name":"Cosmetics","volume":"124 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135810395","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}

The correction of leg telangiectasias is one of the most frequently performed interventions in the Western world. While sclerotherapy remains the gold standard of treatment, several studies have shown comparable efficacy and, in some situations, an even more favorable use of lasers as an alternative treatment option. The most frequent side effect of both treatment options is hyperpigmentation, which usually clears spontaneously in most cases but can be challenging to treat if it persists. The origin of this hyperpigmentation is not fully understood; small studies point to hemosiderin as the causative pigment, at least in post-sclerotherapy hyperpigmentation. More rare side effects of the treatment include ulcerations and scarring. Quality-switched (QS) Nd:YAG lasers have demonstrated good efficacy in treating hemosiderin depositions in the skin, post-inflammatory hyperpigmentation and atrophic scars. We present a case of post-inflammatory hyperpigmentation and scarring after laser treatment of leg telangiectasia with a long-pulsed Nd:YAG laser that was successfully treated using a QS Nd:YAG 1064 nm laser. This case suggests the QS Nd:YAG laser as a possible treatment option in cases of hyperpigmentation with various origins, including hemosiderin and melanin, and scarring after laser treatment of leg telangiectasias.

The objective of this study was to develop effervescent cleansing tablets that can be dissolved and turned into liquid soap, which can be used for bathing or soaking the body. The asiatic-acid-loaded solid lipid microparticles (AASLMs) were prepared via the hot emulsification method followed by cold re-solidification and then freeze-dried to obtained dry powder. The physicochemical properties such as morphology and % entrapment efficiency (%EE) were evaluated. The results revealed that AASLMs have an irregular shape, and the %EE for the resulting AASLMs was 92.04 ± 3.43%. The tablets were manufactured via the direct compression technique. The compatibility test was conducted to ensure that the excipients are compatible with the active ingredient. The angle of repose, Carr’s index, and Hausner’s ratio were studied to evaluate the flowability of the powder blend before compression. The weight of each tablet was set to 1000 mg, and physicochemical characteristics, in vitro dissolution, ex vivo cleansing efficacy, and stability were evaluated. The results showed that the active ingredient was compatible with other excipients, as the results obtained from FTIR spectra indicated the absence of potential chemical interaction between the active ingredient and excipients used in this study. Additionally, all formulations had good flow properties. The effervescence times of selected formulations, F2 and F3, were <5 min, with favorable pH and hardness values. The friability values of all formulations exceeded 1% because the excipients used in effervescent tablets are very fragile. The release of asiatic acid (AA) from the tablets was dependent on the concentration of SLS. In an ex vivo test, it was discovered that the developed products F2 and F3 showed much more effective cleansing efficacy than water. Nevertheless, brown spots appeared in the tablets and the AA content was significantly decreased in both tested formulations after 3 months’ storage at 40 ± 2 °C/75% RH ± 5% RH. The stability study revealed that the developed products were not stable at high temperature and humidity. Therefore, it is recommended that the developed effervescent tablets are not stored at a high temperature.

Acne vulgaris was one of several diseases whose progression was significantly influenced psychologically by the rapid and protracted alteration of daily routines that occurred during the COVID-19 pandemic, especially for specific populations like adolescents. In order to assess their psychological impact and the relationship with the progression of acne vulgaris, this study aims to examine the quality of life, stress, anxiety, and depression of acne patients during the COVID-19 pandemic and their care. This observational, multicenter investigation was carried out in five dermatology clinics in Italy. Data were obtained via a remote telephone interview using questionnaires that were approved by a group of dermatologists and psychiatrists. Evaluations included demographic information, treatment status, disease progression, dietary habits, and employment activities. Some 178 acne vulgaris patients in various stages of systemic or topical medication were included in the study: 47 of 178 (26.4%) patients showed high scores on the HADS anxiety subscale, and 41 of 178 (23%) patients showed high scores on the HADS depression subscale. The Brief Resilience Scale (BRS) was used to measure resilience; 70 patients out of 178 (or 39.3%) showed low resilience (range: 1.00–2.99). In 32 out of 178 patients with PSS, high levels of stress were discovered (18%). Some 50 out of 178 patients experienced alterations in their way of life, including increased acne-related symptoms of relationship humiliation and constraints on everyday activities. Some 52 out of 178 patients (29.2%) said that they felt their condition had gotten worse over the study period. Our findings revealed a potential link between the exacerbation of acne and high levels of anxiety and depressive symptoms, as well as an elevated sense of stress and low or moderate levels of adaptability and resilience.
