Today, UV filters are found as contaminants in a variety of biological fluids and environment, e.g. in vegetable crops and surface water. This is because UV filters are widely used in everyday products. In this context, we focused this study on cosmetic products. The study of 742 cosmetic products, excluding actual sunscreen products, but including hygiene, personal care and make-up products and perfumes revealed that the most common UV filters present are butyl methoxydibenzoylmethane, octyl methoxycinnamate, octocrylene, octyl salicylate and titanium dioxide. Few UV filters are found in the hygiene products and deodorants and toothpastes are completely free of them. Conversely, make-up and perfumes are frequently formulated with at least one UV filter.

Sun protection products serve as part of a strategy to prevent photoinduced skin cancers. The products currently on the market vary considerably, both in terms of their galenic formulation and their composition. Some are formulated using organic UV filters, some using mineral UV filters, and some using a mixture of both types. In this context, healthcare professionals, particularly dermatologists and pharmacists, are faced with selecting the product best suited to the patient/user, especially during summer. Our aim here is to establish a decision tree to enable an informed choice.

Some consumers have become very suspicious of certain health products such as medicines, medical devices and cosmetics. 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.Certaines personnes sont devenues très méfiantes vis-à-vis des différents produits de santé que sont les médicaments, les dispositifs médicaux et les cosmétiques. Dans ce contexte, elles font le choix de réaliser elles-mêmes leurs produits. Le but de ce travail était l’analyse de recettes de produits de maquillage et de démaquillage des yeux, ainsi que de produits de soin des cils et du contour des yeux. Dans cet objectif, nous avons collecté des recettes de produits à faire soi-même sur des blogues et des médias sociaux (chaînes YouTube, comptes Facebook, Pinterest, Instagram et Tiktok) de langue française et de langue anglaise, puis nous les avons analysé d’un point de vue de leur réalisation pratique et de leur composition. 275 recettes de produits utilisables au niveau de l’œil ou de la zone périoculaire ont ainsi été compilées et étudiées. Il ressort de ce travail que les quantités des différents ingrédients sont très imprécises, que les substances proposées ne sont pas adaptées à l’usage visé et que la conservation des produits finis n’est pas suffisamment assurée. Les résultats obtenus suggèrent que les recettes de produits destinés à être utilisés au niveau de l’œil ou dans la zone péri-oculaire ne sont pas sûrs d’emploi et que leur utilisation est susceptible d’engendrer des conséquences relativement graves.
