Mushrooms are edible fungi containing valuable nutrients. They provide attractive bio-active properties, which have confirmed anti-oxidants, anti-aging, and anti-inflammatory properties. Mushrooms possess abundant natural polymers affecting skin hydration and acting as moisturizers supporting skin barrier function. In this study, cloud ear mushroom (Auricularia polytricha) water extract (CW) was produced as a natural polymer to evaluate a new film-forming spray (FFS) containing CW to increase skin hydration and protect transepidermal water loss. CW contained polysaccharides as 748.2 ± 0.02 mg glucose/g extract. CW significantly inhibited the secretion of IL-6 and TNF-α and enhanced skin hydration by increasing aquaporin-3 (AQP3) and filaggrin (FLG) in HaCaT cells. The FFS was formulated using CW, sodium polystyrene sulfonate, and glycerin. The selected formulation contained brown Agaricus bisporus (BE-FFS) evaluated physical appearance, spray angle, spray pattern, and in vitro skin permeation. The BE-FFS has a transparent thin film with suitable occlusive properties, drying time, and physical appearance. Afterward, in vitro skin permeation and human hydration property studies presented the long-lasting effects and provided safety and hydration potential after 4 weeks of use. Overall, all results indicate that the BE-FFS is a natural film-forming spray for skin hydration improvement.

Topical retinoid treatment is considered a standard therapeutic approach for chrono and photo skin aging. Retinol (vitamin A) is the precursor of endogenous retinoids. A prospective, 12-week, randomized, parallel-group trial comparing the combination of vitamins’ oral supplementation (one capsule daily, 50.000 UI vitamin A and 50 mg vitamin E) and a 0.02% retinoic acid topical gel formulation (RG) applied in the evening (Group B) in comparison with the topical RG treatment alone (Group A) was conducted. A total of 60 subjects (men and women, aged >50 years, mean age 60 ± 8 years) with moderate-severe facial skin aging (Glogau score > 2) were enrolled after their written informed consent. Thirty participants were randomly assigned to Group A and 30 to Group B. The primary endpoint was the clinical evaluation of a Skin Aging Global Score (SAGS), at baseline, and after 6 and 12 weeks. A VISIA® (Canfield Scientific, Parsippany, NJ, USA)face sculptor analysis was performed in a subgroup of 20 subjects. Skin tolerability was evaluated in both groups at weeks 6 and 12. In comparison with the baseline, SAGS scores in both groups were reduced by 13% (Group A) and by 14% (Group B) after 6 weeks and by 22% (Group A) and by 27% (Group B) at week 12. At the end of the study, SAGS score absolute reduction in Group B was significantly greater (p < 0.01) in comparison with the absolute reduction in Group A. Both treatment regimens were well tolerated. The combination of medium-high doses of oral retinol supplementation (Vitamin A) and topical retinoic acid gel showed superior efficacy in terms of clinical improvement in comparison with the topical treatment alone in subjects with moderate/severe skin aging.

Oral formulations with natural plant-based extracts represent a safe and promising strategy for skin lightening and anti-dark-spot effects, especially in Asia. This study evaluated the effect of an oral formulation including polyphenol-rich extracts and vitamin C (Belight3TM) on in vitro tyrosinase inhibitory activity and investigated its skin lightening and anti-dark-spot effects in vivo. Tyrosinase inhibitory activity of the formulation was measured with spectrophotometry. A randomized, double-blind, placebo-controlled clinical study was carried out on 58 healthy Asian males and females, aged 45–65. Skin color was measured at baseline, 6 weeks and 12 weeks with digital photographs. Color of dark spots was assessed with spectrophotometry. In vitro, the formulation showed a significant synergistic tyrosinase inhibitory activity of 85% compared to the control. In vivo, 12-week oral administration of the formulation significantly lightened the skin and was significantly better than the placebo. In addition, this formulation induced a slight and significant lightening effect of the dark spots after 6 and 12 weeks. Our findings suggest that the daily oral administration of Belight3TM during 12 weeks appears as an efficient and safe nutricosmetic to lighten the color of the facial skin and dark spots in Asian subjects.

Lifestyle health has been recognized as an evidence-based innovation that defines how everyday behaviors and routines influence the avoidance and therapy of illness and provides an important adjunctive component to overall health. Specifically, an approach with small changes over time can have a dramatic impact on the health and well-being of individuals not only, in general, but also can be applied to skin health. However, lifestyle health factors to improve skin well-being have not been discussed extensively and/or well promulgated. The narrative for this overview focuses on providing a summary for topic background information, but more importantly, presents four lifestyle factors that can improve dermal health [i.e., factor 1: nutrition—diet; factor 2: rest (sleep); factor 3: movement/physical exercise, and factor 4: social and community associations]. This was accomplished by identifying preceding journal reports/reviews covering especially the last five years (January 2018 to July 2023; 164 out of 205 references cited or 80%) using scientific search databases. The main conclusions of this overview encourage the concept that lifestyle health factors such as nutrition/diet, rest/sleep, movement/physical exercise, and community/social interactions support enhanced skin health and well-being with aging. Plus, social media interventions that aim to promote dietary, sleep and physical activity changes might be an application to improve skin health in the future.

Tattooing has been an enduring form of body art since ancient times, but it carries inherent health risks, primarily due to the complex composition of tattoo inks. These inks consist of complex mixtures of various ingredients, including pigments, solvents, impurities and contaminants. This literature review aims to shed light on the organic and inorganic contaminants present in tattoo inks prior to the implementation of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation in 2022. This review shows that the most common contaminants are polycyclic aromatic hydrocarbons (PAHs), with a concentration range of 0.005–201 mg/kg, mainly detected in black tattoo inks, and primary aromatic amines (PAAs), with a concentration range of 0.5–1100 mg/kg, and heavy metals such as lead (0.01–14.0 mg/kg) and chromium(VI) (0.16–4.09 mg/kg) which are detected in almost all tattoo inks. When compared to the new concentration limits outlined in REACH, it is clear that a significant part of these contaminants would be considered non-compliant. However, the results of the review are limited due to the lack of quantitative data on contaminants in tattoo inks. In addition, the future implementation of REACH is expected to lead to changes in the composition of tattoo inks, which will affect the presence of contaminants.

The excessive use of water and plastic packaging in the cosmetic industry imposes the need to develop sustainable alternatives. Moreover, agricultural by-products are reported in the literature to be rich in bioactive properties, namely high antioxidant capacity, suggesting their potential use in cosmetic formulations as substitutes for commercial additives. The aim of this work was the development of a sustainable formulation of solid shampoo, incorporating extracts from mango peel as antioxidants. The characterization of the extracts revealed the presence of several phenolic compounds and a strong antioxidant capacity. Six formulations of solid shampoo were produced by varying the quantity of the additives: tocopherol and butylated hydroxytoluene, used as positive controls, and mango peel (MP) extract. The antioxidant capacity assays demonstrated that the MP extract increased the antioxidant activity of the shampoos, in comparison to the positive controls and the stability tests revealed that the MP extract is a stable ingredient. Hence, it was concluded that the MP extract is a strong source of antioxidants with the potential to replace commercial antioxidants in cosmetics. Thus, it was possible to develop a value-added formulation of solid shampoo, eliminating the use of water and plastic for the packaging, and reusing waste from the food sector.

In spite of the significant progress towards sustainable cosmetics, mass-produced sustainable packaging has proven to be a challenge. The complexity of environmental, economic, social, technological, and policy considerations in conjunction with varying consumer behaviors and corporate goals can make it difficult to select an optimal strategy across heterogeneous supply chain components spread over the globe, and the cost and effort of developing, testing, and validating alternative strategies discourages empirical exploration of potential alternatives. This review discusses the challenges that can be expected in the context of broader sustainability efforts, as well as the experience gained in related fields, such as sustainable cosmetics and sustainable packaging, to identify potential pitfalls as well as promising trends towards the development of sustainable color cosmetics packaging. The findings suggest there may be little to be gained from attempting to induce customers to change their behavior, waiting for a significant increase in global recycling infrastructure, or expecting regulatory constraints to substitute for the lack of technological and business solutions. A research strategy is delineated towards the development of sustainable packaging that, with appropriate policy support, could minimize externalities and provide mass-produced packaging that is acceptable to both consumers and producers.

The use of sunscreen is the most effective way to minimize sun damage to the skin. Excessive UV exposure is linked to an increased risk of melanoma and accelerated skin aging. Currently, approved UV filters fall into two categories: chemical- or mineral-based filters. Besides approved filters, there are numerous SPF-boosting additives that can be added to sunscreen products to enhance their efficacy. This manuscript shows the potential application of the novel SPF booster, Bacillus Lysate, developed from Bacillus pumilus PTA-126909, which was derived from research aboard the International Space Station. The addition of the 3.5%, 7%, or 10% Bacillus Lysate resulted in a 33%, 29%, and 22% boost in the SPF values of an SPF 30 sunscreen, respectively. The potential use of extremophiles and their byproducts, like the Bacillus Lysate presented here, may be a promising alternative SPF booster for the sunscreen industry.

Turmeric and ginger, widely used rhizomes in culinary arts, have several beneficial biological activities, such as hypoglycemic, hepato-protective, antimicrobial, and antioxidant properties. This work investigated the effects of three phenolic extracts isolated from turmeric and ginger rhizomes on anti-inflammatory and healing properties using the solid–liquid extraction method. Wistar rats were used as a biological model. The anti-inflammatory activity was evaluated on induced edema in the rat’s hind paw using carrageenan (1%). Paw volume was measured at 0 min, 45 min, 3 h, and 5 h. Treatment with turmeric and ginger extracts, administered at a dose of 100 mg/kg, revealed a reduction in edema volume by 98.8%, 94.8%, and 98.3% using an aqueous extract of turmeric, ethanolic extract of turmeric, and methanolic extract of ginger, respectively. The healing activity parameters of induced burns on the rat’s dorsal region in nine groups (7 rats each) were monitored daily throughout the experiment’s duration. Results showed that the application of creams composed of petroleum jelly dispersing turmeric and ginger extracts to wounds at a dose of 100 mg/kg g induced complete healing after 19 days while the negative control was only 60% cured. On day 14, the aqueous, ethanolic, and methanolic turmeric extracts nearly resulted in complete tissue repair by 95.26%, 98.34%, and 87.39%, respectively. According to the chromatographic analysis (Sephadex G50 column), there is a variation in the molecular weight distribution of phenolic compounds (polymers, oligomers, and monomers) in the three studied extracts, which has a differential effect on the anti-inflammatory and wound healing activities of the extracts.

Results showed that the application of creams composed of petroleum jelly dispersing turmeric and ginger extracts to wounds at a dose of 100 mg/kg g induced complete healing after 19 days while the negative control was only 60% cured. On day 14, the aqueous, ethanolic, and methanolic turmeric extracts nearly resulted in complete tissue repair by 95.26%, 98.34%, and 87.39%, respectively. According to the chromatographic analysis (Sephadex G50 column), there is a variation in the molecular weight distribution of phenolic compounds (polymers, oligomers, and monomers) in the three studied extracts, which has a differential effect on the anti-inflammatory and wound healing activities of the extracts.","PeriodicalId":10735,"journal":{"name":"Cosmetics","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135896038","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}

Eyelashes, in addition to fulfilling eye-protective functions, generate an aesthetic impact. Latanoprost is a prostaglandin analog, commonly used for the treatment of glaucoma and intraocular hypertension. The side effect reported most often is the stimulation of eyelash growth. The aim of this study was to evaluate the efficacy and safety of latanoprost in inducing eyelash growth and darkening. Thirty healthy volunteers were recruited in a 3-month, randomized, double-blind, placebo-controlled pilot study. A transparent eyelash mascara was used as a vehicle. The placebo group (n = 15) received only the vehicle, and the latanoprost group (n = 15) received the vehicle + 0.005% latanoprost. The participants were asked to apply the latanoprost topically to the eyelashes while avoiding entry into the eye, daily at night. The latanoprost group showed a significant increase in eyelash length and color change, while the placebo group maintained eyelash length and color throughout the study. The intraocular pressures of all the participants were maintained in normal ranges (10–20 mmHg). Topical application of both the placebo and the latanoprost medications was well tolerated; none of the participants withdrew, generated side effects, or developed any ophthalmic pathology. In conclusion, latanoprost is effective and safe to stimulate the growth of eyelashes.
