This can lead them to choose to make such products themselves. The aim of this work was therefore to analyse recipes for eye makeup and makeup removal products, as well as eyelash and eye contour care products. We collected recipes for do-it-yourself products found on blogs and social media (YouTube channels, Facebook, Pinterest, Instagram and TikTok) in French and English and then analyse their composition as well as how practical it is to make these recipes. We compiled and studied 275 recipes for products that can be used in or around the eye (periocular area). This work has shown that the quantities of the various ingredients are very imprecise, that the proposed substances are not suitable for the intended use and that the preservation of the finished products is not sufficiently guaranteed. The results obtained suggest that recipes for products intended for use in the eye or in the periocular area are not safe to use and that their use is likely to have relatively serious consequences.

A review of homemade cosmetics based on a study of 150 blogs and their authors / Céline Couteau in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 45, N° 4 (08/2023)  

[article]  inINTERNATIONAL JOURNAL OF COSMETIC SCIENCE > Vol. 45, N° 4 (08/2023) . - p. 569-547 Titre : A review of homemade cosmetics based on a study of 150 blogs and their authors Type de document : texte imprimé Auteurs : Céline Couteau, Auteur ; Alvarez Rueda Nidia, Auteur ; Bérénice Breton, Auteur ; Laurence Coiffard, Auteur Année de publication : 2023 Article en page(s) : p. 569-547 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Blogs Cosmétiques Do it yourself Produits de beauté Réseaux sociaux (Internet) Index. décimale : 668.5 Parfums et cosmétiques Résumé : Do-it-yourself methods have been used in many fields (cooking, home improvement, decoration, gardening, etc.) for a long time, but their application to the cosmetics sector is relatively recent and seems to be linked to a number of health scandals. The objective of this work is to analyse homemade cosmetics based on a study of blogs and their authors. We made a study of 150 blogs advocating homemade cosmetics. With only one exception, the blog authors were women, mostly in their thirties, with no specific qualifications or knowledge in the fields of cosmetic formulation or chemistry. The most highly qualified of them (with at least a Master's degree) had studied marketing and management. So, the situation is an illustration of the Dunning-Kruger effect, with authors believing themselves to be qualified in a field wholly outside their own. This leads to scientific falsehoods about, for example, preservatives like parabens and phenoxyethanol. On the contrary, the relevance of the ecological motivation frequently mentioned in these blogs is undeniable.
