**F ´atima Garc´ıa-Vill ´en** is currently a post-doctoral researcher. She graduated from the Official Master's Degree in Drug Research, Development, Control and Innovation of Medicines (University of Granada) in 2016. She graduated as a Doctor in Pharmacy in 2020 (University of Granada). Her PhD was supported by a Spanish grant (FPU). During this period, she was part of the Department of Pharmacy and Pharmaceutical Technology (Faculty of Pharmacy, University of Granada). Up until today, inorganic excipients such as zeolites (Master's degree) and clay minerals (PhD) have been the backbone of her research. In particular, her research has been focused on the formulation and characterization of medicinal and cosmetic formulations. In particular, her attention is centered on the development of formulations for skin and wound treatments. She has published over 25 papers, including original papers, reviews, and book chapters, and participates as a reviewer of the indexed journal *Applied Clay Science*.
