Analysing the chemistry in beauty blogs for curriculum innovation

Abstract

Cosmetics play an important role in our everyday lives. However, the variety of different products and brands appears confusing to consumers. Products vary from basic, indispensable, everyday items such as soaps, shower gels and shampoos, to decorative cosmetics and high-end skin creams with specific, “innovative” ingredients for every skin type imaginable. In recent years, beauty blogs have become a popular platform to seek information on cosmetic products. Such blogs often contain chemistry-based content, which is only rarely written or at least double-checked by someone with a scientific background. Often such blogs reach a readership of several million users per month. But which role do chemical aspects play in beauty blog texts? This paper describes a qualitative content analysis of 60 recent posts from six popular English-language beauty blogs. The texts were coded according to categories such as the number of chemistry-related terms, supporting information for such terms, positive and negative claims regarding chemical aspects, references to studies etc. Based on the distribution of the categories, three main types of blogs could be distinguished: The “scientific type”, the “semi-scientific type” and “the non-scientific type”. By color-coding the different categories, a difference between these types can be easily depicted. The paper will discuss first findings and ideas on how to make use of corresponding analyses of beauty blogs for the teaching of chemistry.

Inoculating students against science-based manipulation strategies in social media: debunking the concept of ‘water with conductivity extract’

“…Recent data show that the number of social-media users worldwide increased from roughly a billion in 2010 to 3.6 billion in 2020 (Tankowska, 2021). Many of the topics discussed on social media have a scientific background, but only in the rarest of cases are actual experts speaking here (Belova and Velikina, 2020). Because anyone can create and share content on platforms such as Instagram, Facebook and TikTok (thus eliminating the previously existing media gatekeepers), misinformation can spread rapidly and in extreme cases can lead to social divisions, as can currently be seen in the debates surrounding the COVID-19 pandemic (Archila et al, 2021).…”

Collagen in the media: An analysis of news published between 2016 and 2018

“…It is therefore worth exploring to what extent the information made available through the media to consumers about products that the collagen industry launches on the market 4 is consistent with scientific evidence. In this sense, it is impossible not to notice that the media play a very significant role in the establishment and consolidation of beliefs that people have about various scientific issues, such as health, 5 energy, 6 climate change 7 evolution, 8 chemical composition of cosmetics, 9 and antibiotic resistance, 10 or the myths about nutritional content of foods, 11 to name a few examples. Thus, it is reasonable to think that the media exerts a notable influence on the consolidation of beliefs regarding the usefulness of collagen‐based products.…”
