: Given the strictly non-interventional nature of this study, in which no products were applied to the volunteers, formal ethics committee approval was not required. Written informed consent authorizing the use of their images for research and scientific publication was obtained before the study from all participating volunteers. Furthermore, to ensure strict anonymity and protect privacy, the photographs presented in this manuscript have been heavily cropped.
