Abstract
Counterfeiting of healthcare products is a global scourge affecting pharmaceuticals, medical devices and cosmetics, especially perfumes. To date, perfumes have been the most well-known counterfeit cosmetics. The aim of this study is to demonstrate counterfeit sunscreens without any photoprotective efficacy. Two creams bought online were tested. Firstly, sun protection factor (SPF) and protection factor ultraviolet A (PF-UVA) efficacy indices were determined using an in vitro method. Secondly, the dosage of UV filters was determined by high-performance liquid chromatography. The SPF and PF-UVA values were equal to 1, indicating a lack of photoprotection. The creams studied do not contain any UV filter and therefore pose a significant risk to users when exposed to the sun. Counterfeit sunscreen products expose their users to serious consequences as they do not offer any protection.
期刊介绍：
The European Journal of Dermatology is an internationally renowned journal for dermatologists and scientists involved in clinical dermatology and skin biology.
Original articles on clinical dermatology, skin biology, immunology and cell biology are published, along with review articles, which offer readers a broader view of the available literature. Each issue also has an important correspondence section, which contains brief clinical and investigative reports and letters concerning articles previously published in the EJD.
The policy of the EJD is to bring together a large network of specialists from all over the world through a series of editorial offices in France, Germany, Italy, Spain and the USA.
