In this regular feature, aesthetic nurse Claudia McGloin presents a brief synopsis of a range of recently published articles on medical aesthetics. Research roundup aims to provide an overview, rather than a detailed summary and critique, of the papers selected. Should you wish to look at any of the papers in more detail, a full reference is provided at the end of each study summary
People have long been enjoying ‘Do it Yourself’ (DIY) activities for a variety of hobbies, such as gardening, home improvements and cooking. But only recently has this been applied to DIY cosmetics. The authors of this paper note that this has been linked to several scandals in health.
The aim of this study was to examine homemade cosmetic products. This was carried out by assessing a total of 150 French-language blogs that encouraged the public to make homemade cosmetics. Of the 150, the vast majority were written by women who possessed no proven qualifications or specific knowledge in the field of chemistry or cosmetic formulation. Among the blogs, false knowledge was spread on, for instance, certain parabens and phenoxyethanol, which may be detrimental to readers experimenting with DIY cosmetics.
The authors note that this could be a demonstration of the Dunning-Kruger effect—a situation whereby inividuals with limited knowledge of a topic overestimate their expertise in it. The authors therefore caution that this may lead to false scientific information being circulated.
