Microscopic prokaryotic and eukaryotic algae (microalgae), which can be effectively grown in mass cultures, are gaining increasing interest in cosmetics. Up to now, the main attention was on aquatic algae, while species from aeroterrestrial and extreme environments remained underestimated. In these habitats, algae accumulate high amounts of some chemical substances or develop specific compounds, which cause them to thrive in inimical conditions. Among such biologically active molecules is a large family of lipids, which are significant constituents in living organisms and valuable ingredients in cosmetic formulations. Therefore, natural sources of lipids are increasingly in demand in the modern cosmetic industry and its innovative technologies. Among novelties in skin care products is the use of lipid nanoparticles as carriers of dermatologically active ingredients, which enhance their penetration and release in the skin strata. This review is an attempt to comprehensively cover the available literature on the high-value lipids from microalgae, which inhabit aeroterrestrial and extreme habitats (AEM). Data on different compounds of 87 species, subspecies and varieties from 53 genera (represented by more than 141 strains) from five phyla are provided and, despite some gaps in the current knowledge, demonstrate the promising potential of AEM as sources of valuable lipids for novel skin care products.

The skin care industry has become very competitive today. The demand for skin care products has grown rapidly due to the growth in the population of working females and the penetration of Korean culture among Malaysians. Hence, this study aims to investigate the influence of promotional mix on buying behaviour of female consumers towards skin care products. This study has recruited 200 female respondents from Melaka using convenience sampling. The data was collected using a set of self-administered questionnaires. Advertising, sales promotion, direct marketing, personal selling and public relations were included in the research model to predict buying behaviour of female consumers towards skin care products. Data analysis which involves measurement model and structural model were performed using PLS-SEM. Sales promotion and public relation both influence buying behaviour significantly. Advertising, direct selling and personal selling, however, were found to be non-significant. The findings have thus implied that sales promotion and public relation are important factors of buying behaviour of female consumers towards skin care products. This study has provided valuable information and insightful input to the marketers of skin care products.

Witch hazel extracts have been used for decades as cosmetic ingredients in skin care products. Our present study aims to evaluate its potential in anti-pollution products using a previously reported in vitro model. Calcium is a universal second messenger, and we used human respiratory and skin cells to detect changes in intracellular Ca2+ concentrations upon particulate matter contact. Both an increase in pro-inflammatory markers and a decrease in tight junction proteins were confirmed, as previously reported. Witch hazel stem and leaf extract showed significant attenuation of Ca2+ response upon the challenge; it displayed systematic regulations of the signal generator, PAR-2; a pro-inflammatory marker, NF-κB; and a tight junction protein, Occludin. We identified hexagalloylglucose from the extract and concluded that it is a major component regulating protection from particulate matter. Based on these results, witch hazel extract containing hexagalloylglucose is an active ingredient in anti-pollution skin care products.

Tyrosinase is a multifunctional copper-containing oxidase enzyme that initiates melanin synthesis in humans. Excessive accumulation of melanin pigments or the overexpression of tyrosinase may result in skin-related disorders such as aging spots, wrinkles, melasma, freckles, lentigo, ephelides, nevus, browning and melanoma. Nature expresses itself through the plants as a source of phytochemicals with diverse biological properties. Among these bioactive compounds, flavonoids represent a huge natural class with different categories such as flavones, flavonols, isoflavones, flavan-3-ols, flavanones and chalcones that display antioxidant and tyrosinase inhibitor activities with a diversity of mechanistic approaches. In this review, we explore the role of novel or known flavonoids isolated from different plant species and their participation as tyrosinase inhibitors reported in the last five years from 2016 to 2021. We also discuss the mechanistic approaches through the different studies carried out on these compounds, including in vitro, in vivo and in silico computational research. Information was obtained from Google Scholar, PubMed, and Science Direct. We hope that the updated comprehensive data presented in this review will help researchers to develop new safe, efficacious, and effective drug or skin care products for the prevention of and/or protection against skin-aging disorders.

PurposeA number of types of scarcity messages are often used in Internet advertisements, but all these types have not been directly compared to each other.Design/methodology/approachCollege students (n = 789) were surveyed about five advertising choices for luxury skin-care products consisting of scarcity messages of high-demand, low-stock, limited-time, countdown timer and regular advertising without any scarcity message. Outcomes were product classification attitudes of functional and symbolic and psychological attitudes of persuasion knowledge and advertising skepticism.FindingsThe study found that high-demand message had greater functional attitudes and greater symbolic attitudes than regular advertising. Limited-time message had greater symbolic attitudes than regular advertising. High-demand message had lower advertising skepticism attitudes than regular advertising.Practical implicationsThe authors recommend that when a luxury skin-care product is in high demand, that marketers should use high-demand messages in their advertising. Marketers of luxury skin-care products may also benefit from using limited-time message advertisements.Originality/valueThis is the first study to directly compare the scarcity message advertising types of high-demand, low-stock, limited-time, countdown timer with regular advertising without any scarcity message.

The purpose of this research is to find out more information on the satisfaction of customers on the quality of services of local skincare products. Quality is the most important element that is closely related to the satisfaction of a customer. The chosen brand that has been observed for this research is NSA Beau that is formulated from their own serum called the AINAA Serum. Customers face difficulties regarding the availability and quality of skin care products. Besides that, the local industries in skincare products are also facing problems such as low-quality products, that influence the perspective of the person. This includes bad reviews due to their ineffectiveness on certain people who have a certain type of skin. It is suggested that the level of quality of service is an indication of the organization’s ability to meet the desires and demands of customers’. Therefore, the objective of this study is to examine customer satisfaction based on their perceptions of local skincare products based on its quality. It also indicates the discovery of the local skincare products in Malaysia that are used by the society on a daily basis. Hence this research examines the reliability of these local skincare products. Online surveys were conducted on university students and working adults in Malaysia to find their perspectives and opinions on the quality of a brand when the brand is used, the effectiveness of its promotion, the image of the brand and its preference. It can be seen that quality is the most important factor for a person to buy especially a skincare product. The research also shows that there are specific important reasons in decision making to purchase a skincare product. An example is the effectiveness of the brand especially its quality, advertisement of the product, the image the brand holds and other reasons that effect the variables.

Mucins are a highly glycosylated protein family that are secreted by animals for adhesion, hydration, lubrication, and other functions. Despite their ubiquity, animal mucins are largely uncharacterized. Snails produce mucin proteins in their mucous for a wide array of biological functions, including microbial protection, adhesion and lubrication. Recently, snail mucins have also become a lucrative source of innovation with wide ranging applications across chemistry, biology, biotechnology, and biomedicine. Specifically, snail mucuses have been applied as skin care products, wound healing agents, surgical glues, and to combat gastric ulcers. Recent advances in integrated omics (genomic, transcriptomic, proteomic, glycomic) technologies have improved the characterization of gastropod mucins, increasing the generation of novel biomaterials. This perspective describes the current research on secreted snail mucus, highlighting the potential of this biopolymer, and also outlines a research strategy to fulfill the unmet need of examining the hierarchical structures that lead to the enormous biological and chemical diversity of snail mucus genes.

The cosmetics and toiletry industry has growing up very fast. In 2016, the total global revenue cosmetics industry amounted to USD$444 billion. According to Lee, Goh, & Noor ( 2019), the skincare products dominated the cosmetics and toiletry market with a market value of approximately USD$ 120 billion. Between 2012 and 2019, the global skincare market expanded by 41.8 percent, and by 2025, it is expected to be worth $189 billion (Ledesma, 2020). The skin is the largest organ in the body, hence, many people will find ways to protect it, one of the way people are using to protect the skin is to apply any supplement on skin to keep the good condition of the skin. However, according to Cunningham (2014), the used of chemical items in the cosmetic skin care industry is extremely unregulated. For example, Parabens that cause breast cancer are found in cosmetics. The chemical used in the skin care products had rise the attention of the users to start to pay attention on the ingredient of the skin care products. One of the way people are using in order to avoid the harmful chemical in skin care products is to to choose skin care with natural ingredient (Espitia, 2020), this happend especially among the younger consumers (Boon et al., 2020; Hsu et al.,2017). The green skincare industry is growing rapidly. Green skin care, according to previous studies (Fauzi & Hashim, 2015; Hsu et al., 2017), is any skin care products which can preserve or enhance the natural environment by conserving energy or resources and decreasing or eliminating the usage of harmful agents, pollution, and waste. Studies showed there is an increasing in the consumption of green skincare products and toiletries by 45%, from a peak of RM 1.6 billion (in 1998) to RM 2.2 billion (in 2010), with sales estimated to exceed $1.1 billion in 2010 among young people (Boon et al., 2020).

AbstractSkin hydration is generally evaluated using devices that measure capacitance or conductance. A new technology (Biodisplay) was developed to provide accurate measurements of skin hydration at the contact site. This study aimed to test the reliability of the Biodisplay by comparing its performance results with those of similar devices currently used to objectively assess skin hydration. For each of the 30 participants, skin hydration was measured at each of the defined points on the forearm three times using the Biodisplay and a Hydration probe (HP), an objective measurement device of skin hydration. We also evaluated skin hydration of the arm using both tools after applying moisturizers to evaluate interferences from skin care products. The reliability and reproducibility of each device were analyzed by intraclass correlation coefficients (ICC), and the correlation of the two devices was evaluated by Pearson’s correlation coefficients (PCC). The Biodisplay demonstrated moderate-to-excellent reliability (ICC: (0.741–0.980)), but lower reliability than the HP (ICC: (0.953–0.980)). The skin hydration measurements made by the two devices were demonstrated to be significantly correlated, showing moderate correlations (PCC: 0.601). The Biodisplay can provide reasonably reliable and accurate measurements for skin hydration with the strong points of portability and accessibility.
