Abstract

The skin is a multifunctional organ that performs various vital functions, besides being essential for maintaining human health and well-being. There are two widely used classifications to describe skin phototypes. The first is the Fitzpatrick classification, and the second is the Individual Typology Angle (ITA) based classification. Despite the new techniques for skin characterization, the literature on different skin phototypes, especially black skin, remains scarce. Furthermore, it is known that Brazil is a racially mixed country with rich ethnic diversity, which necessitates a continuous effort to understand and address the particularities and specific needs of different skin types. Moreover, the characterization and comparison of different skin phototypes, based on their hydrolipidic and morphological characteristics, can contribute to reducing disparities in access to care for black skin. To achieve this, complex and detailed studies of the characteristics of different skin phototypes are necessary. Thus, the application of advanced biophysical techniques and skin imaging analysis, which allow for the non-invasive and real-time evaluation of skin characteristics in vivo, is important in clinical studies concerning the understanding of skin biology. In this context, the present study aims to evaluate the hydrolipidic and morphological characteristics of different skin phototypes using biophysical techniques and skin imaging. Ultimately, the study provides a contribution not only to the understanding of skin biology within the Brazilian population but also to the advancement of research and development of more innovative cosmetic products that cater to the specific needs of consumers.
