Population aging was a global trend, and the most obvious thing after aging was the change in skin appearance. Therefore, the active ingredients that delay skin aging were particularly noticed. Past studies had pointed out that Chinese herbal extracts can improve skin elasticity, reduce wrinkles and melanin precipitation. The purpose of this paper is to explore whether combining hydrolyzed collagen with Chinese herbal extracts can improve skin conditions and achieve anti-inflammatory effects.

Fifty subjects were randomly divided into collagen or placebo groups, and one bottle of collagen or placebo drink was used every day for four weeks, after which skin and inflammatory factors were tested.

In comparison with the baseline results, the skin parameters were improving after four-week intervention. In addition, the IL-6, IL-8, TNF-a were significantly decreased and tissue inhibitor matrix metalloproteinase 1 (TIMP-1) was increased after four-week hydrolyzed collagen intervention.

This study showed that hydrolyzed collagen combined with Chinese herbal extracts can improve the condition of the skin, and can also reduce inflammatory associated factors, thereby achieving anti-aging effects.

The purpose of this paper is to examine the dual influence of traditional Chinese and national Singaporean cultural values on the attitude towards skin beauty and the purchase intention relating to skin care cosmetics among Chinese Singaporean women. It aims is to investigate how ethnic and national cultures might interact to influence the attitude towards skin beauty and hence the willingness to buy skin care products.

A survey of 370 Chinese Singaporean women was conducted to test the proposed links. The study adopts an empirical approach using structural equation modelling.

Both traditional Chinese and national Singaporean cultural values impact the attitude of Chinese Singaporean women towards skin beauty and their willingness to buy skin care cosmetics. The components of the traditional Chinese values (Buddhism, Daoism and Confucianism) and national Singaporean values were found to have differing impact on the attitude towards skin beauty and the purchase intention of skin care cosmetics among Singaporean women. Confucianism was found to have a very strong impact on skin fairness and whitening, national Singaporeans' values were found to have a strong impact on skin anti‐ageing, and Buddhist values were found to have moderate impact on attitude towards skin smoothness and skin fairness and on the willingness to buy skin smoothening and skin whitening cosmetics.

Even though the sample can be considered large, given the number of variables in the model, it would be wise to rely on a larger sample. In addition, the research was about specific cosmetics products, namely those related to skin care. It is judicious to extend the analysis to other categories and types of products. For expatriate ethnic groups, it is recommended that marketers think about the interaction between their traditional values and the values of the host country, as these have dual effects on their attitudes and hence on their buying intention. The interaction between these values is not static across products. It varies in size and combination across types of attitudes and products.

Traditional ethnic and national cultural values have differing impact in terms of significance and size on the attitude towards face beauty. Hence, marketing actions such as positioning and advertising should be customized accordingly, to target at these values in an attempt to influence attitude, and hence purchase behavior. Attitude plays a mediating role between cultural values and purchase intention. Influencing consumers' willingness to buy involves influencing their attitudes.

Few works have surveyed the dual influence of national and ethnic values on a specific ethnic subgroup in Asia. To the authors' knowledge, there no previous research has been conducted for Singapore. This paper demonstrates that it is important for the marketer to take into account Singaporeans' national and ethnic values while marketing to them.

Rambutan (Nephelium lappaceum), a ubiquitous fruit in Southeastern Asia, was rich in vitamins and phytochemicals, which were beneficial for improving of skin conditions. The fermentation process increased phytochemicals and antioxidant capacity. Thus, the purpose of this paper is to examine whether phytochemicals can be increased through the fermentation process of rambutan extracts to improve skin aging.

In this study, the authors used the three stages of fermentation with Saccharomyces cerevisiae, Lactobacillus plantarum TCI028 and Acetobacter aceti under red light to develop a fermented rambutan extract.

The level of polyphenols of red-light-based fermented rambutan extract (RLFRE) were significantly increased 108.9% (p < 0.01) and 97% (p < 0.01) compared with fermented rambutan extract (FRE) and pure rambutan extract (RE), respectively. The human skin fibroblasts treated with 0.03 or 0.06% of RLFRE can significantly decrease reactive oxygen species (ROS) levels by 0.74- (p < 0.001) and 0.84-fold (p < 0.001) compared with H₂O₂ group, respectively. And 0.03% of RLFRE can significantly increase in elastin content by 1.13-fold (p < 0.05). Also, ten compounds were identified including one new phenolic compound and nine known compounds from RLFRE. Moreover, red light could enhance the levels of compounds 4, 9 and 3 by 5, 2.5 and 2.5-fold, respectively, relative to the results of FRE. The last, RLFRE isolated compounds significantly facilitated the elastin content on fibroblast (compound 1, 7, 9, 10 compared with control: p < 0.001, compound 2 compared with control: p < 0.001).

In short, this was the first study to unveil that the red-light-based fermentation can enrich the antioxidant content in a rambutan extract and its product had the potential to be developed a functional product for health-promoting effects such as skin aging.

This paper aims to observe the possible relationship between skin color, sun exposure level, UV protection and food intake and serum levels of 25(OH) D in Japanese older adults.

Elderly (n = 131; 65-93 years old), followed by the Tokyo Metropolitan Institute of Gerontology in the Kusatsu (36°N) received a self-applicable questionnaire about the quantity and quality of the daily sun exposure and behavior to avoid the sun. A color analyzer measured each red (R), green (G) and blue (B) component of skin color, and dietary vitamin D was estimated by food frequency questionnaire. Serum 25(OH) D levels were collected and categorized as sufficiency (>30 ng/mL), insufficiency (between 20 and 30 ng/mL) and deficiency (<20 ng/mL).

High proportion of participants had insufficiency (53 per cent) and deficiency (25 per cent) levels of 25(OH) D. Insufficiency levels were more prevalent in women (57 per cent, p = 0.048) and in participants that use gloves (49 per cent, p = 0.054) and sunscreen on face (76 per cent, p = 0.003) as a sun protection way. Participants with sufficiency levels of 25(OH) D presented lower values of R (p = 0.067), G (p = 0. 007) and B (p = 0.001) of skin color (what is meaning darker skin) and a higher fish intake (12 times per week).

The study is a cross-sectional design and brings a potential for measurement error in the recorded subjective variables. There is a memory bias in self-reported sun exposure and food consumption; however, in the multivariate analysis, it was demonstrated a significant association. Second, although the authors have sought to evaluate a number of variables that could affect the skin’s ability to synthesize vitamin D, there are many other factors that may affect this ability that could not be accounted for. Another limitation was the assessment of self-reported ultraviolet exposure data rather than direct measurement of exposure.

It was also concluded that darker skin color (a surrogate of longer-term sun exposure) participants had a lower prevalence of vitamin D insufficiency in this ethnic homogeneous population. When accessing patients’ skin color, the clinician must account for his or her ethnicity.

Governments should regulate supplementation or food fortification with vitamin D, with special focus in countries with geographical location of insufficient solar radiation for skin synthesis of this vitamin. With this, it becomes a priority that a safe sun exposure ensures the sufficient serum levels of 25 (OH) D without the use of supplements.

This report was the first to analyze skin color components associated to vitamin D levels, finding that blue and green colors were significant. The clinical implication of this find is yet to understand. It was also concluded that darker skin color (a surrogate of longer-term sun exposure) participants had a lower prevalence of vitamin D insufficiency in this ethnic homogeneous population. When accessing patients’ skin color, the clinician must account for his or her ethnicity.

This review deals with the pros and cons of ultraviolet (UV) radiation on human beings and the role of textile clothing and the chemicals used for textiles to protect from their harmful effects.

UV radiation (UVR) which has further divided into UVA, UVB, and UVC. Almost 100% of UVC and major portion of UVB are bounced back to stratosphere by ozone layer while UVA enters the earth atmosphere. Excessive exposure of solar or artificial UVR exhibit potential risks to human health. UVR is a major carcinogen and excessive exposure of solar radiation in sunlight can cause cancer in the lip, skin squamous cell, basal cell and cutaneous melanoma, particularly in people with the fair skin.

This article aims to provide a comprehensive overview of the harmful effects of UVR on human skin, factors affecting UV irradiance and factors affecting UV protection offered by textile clothing.

Effect of fiber properties, yarn properties, fabric construction, fabric treatments and laundering has been reviewed along with the identification of gaps in the reported research. A comparison of inorganic and organic UV absorbers has also been given along with different testing and evaluation methods for UV protective clothing.

The primary aim of the research reported here is to provide strategic guidance for the development of a national communication strategy to improve sun protection practice amongst young people.

The research adopted an exploratory approach, employing qualitative focus groups to represent three population groups, mothers, teenagers and young adults living independently of the family home. A total of 12 focus groups were conducted (with six to eight participants per group) in the UK. Participants were recruited door‐to‐door using quota sampling methods.

Consistent with other studies, awareness of sun protection measures was high compared with actual practice. A number of factors were identified which help to explain this behaviour deficit. These include environment and exposure context, financial cost, understanding of protection process, behavioural influence and control, experiential learning and benefits attached to tanning.

While the findings highlight the importance of supporting parents through the provision of information and guidance, they also identified a need to develop initiatives specifically tailored to meet the needs of young people as they achieve independence.

The incidences of skin cancer have been rising worldwide due to excessive exposure to sunlight. Increase in exposure to ultraviolet (UV) radiation from sunlight results in skin damage such as sunburn, premature skin ageing, allergies and skin cancer. Medical experts suggest several means of protection against ultraviolet radiation, including use of sunscreens, avoidance of the sun at its highest intensities, and wearing clothing that covers as much of the skin surface as possible. This paper provides insight on how UV absorbers can be efficiently used with textile material to protect human skin from harmful UV radiation. The manufacturers of various UV absorbers and their commercial products are reviewed and discussed. The interacting mechanism of UV absorbers with textile clothing for providing UV protection and an evaluation of the performance of UV absorbers are summarized.

Shamika was a lawyer by profession and had a successful career with leading law firms in India, North America and Hong Kong. She was passionate about beauty and skincare and developed a keen interest in that business. Shamika extensively researched brand management, supply chain and production. She had a burning desire to be an entrepreneur in the skincare business. So, she founded the brand “d’you”.The skin care industry in India had seen massive growth. There was a huge increase in people’s interest in cosmetics because of the rapid rise of the middle class. The skincare industry was dominated by firms offering various herbal products. Multiple product categories and a large amount of information confused the end-consumers. Shamika identified an opportunity to offer a skincare product to eliminate the need for a consumer to use multiple serums and compete with products of repute from the international market.South Korea was the top manufacturing hub for skincare products for all leading international brands. Shamika approached many manufacturers there to produce a unique formulation for her. It was challenging to get them interested because of the lack of big orders and the language barrier. Phoenix Cosmetics, a top R&D lab, agreed to partner with Shamika.In spite of severe opposition from her family, Shamika established d’you. She had to figure out customs duties, imports and food and drug regulations. She had to get specialists on board early to avoid time and cost overruns. To be cost-effective, Shamika innovated her promotion strategy. A special airless pump packaging from South Korea was finalised for the product.The pandemic outbreak, national lockdown and pressures of trying to run the business alone were very taxing for Shamika. She struggled to manage the timelines with various agencies, engage with Phoenix and maintain a steady flow of imports from South Korea.After the relaxation of lockdown, Shamika launched “Hustle”, an age- and gender-neutral solution to the skincare woes, in October 2020. She extensively used digital marketing and social media for product promotion and set high service standards. Hustle was recognised in micro beauty awards as the best serum in India. The leading fashion magazines reviewed it very positively. The sales zoomed up.Shamika initiated discussions with venture capitalists (VCs) to scale up. VCs, though positive, were surprised that she had no prior background in skincare. She strategised to create new products with Phoenix, who now desired to collaborate with her after the success of Hustle.Shamika felt the need to expand her team because of the workload stress. She followed the rolling business plan, allowing an immediate course correction because of the dynamic business scenario. She desired to delegate day-to-day operations to the professionals. She would mainly focus on strategising. Shamika was raring to grapple with the challenge of scaling up the business.
