Traditionally, cyclodextrins have been extensively applied in the food industry owing to their functionality and safety profile. However, their use in cosmeceuticals, a rapidly growing area that lies between cosmetics and pharmaceuticals, remains relatively underexplored. Given the increasing demand for scientifically validated, high-performance skincare formulations, cyclodextrins are emerging as promising compounds that can address several formulation challenges. The principal question is whether cyclodextrins represent a worthwhile investment for the future of cosmeceutical innovation. This article aims to provide a comprehensive, evidence-based overview of the current and potential roles of cyclodextrins as safe, effective, and multifunctional carriers in advanced skincare science. The current state of research on the application of cyclodextrins in cosmeceutical formulations is evaluated, with particular focus on active ingredients commonly used in dermatological care, such as vitamins A and C, coenzyme Q10, kojic acid, arbutin, and UV filters. For each of these compounds, relevant in vitro, in vivo, and clinical studies are reviewed in order to assess how cyclodextrin complexation influences key parameters, including solubility, stability, controlled release, skin penetration, and the reduction in adverse reactions. In addition, the use of cyclodextrins in the treatment of dermatological conditions such as acne, psoriasis, and rosacea is examined, highlighting their potential value, particularly in combination with azelaic acid and salicylic acid, well-known agents used to manage these conditions. Beyond their advantages, the limitations and challenges that currently restrict broader implementation of cyclodextrins in cosmeceuticals are also discussed, including cost variability, solubility constraints with certain substances, formulation incompatibilities, and regulatory considerations. Future perspectives are explored, particularly the development of novel modified and amphiphilic cyclodextrins, as well as their integration into nanotechnology-based systems and into intelligent, personalized skincare.<\/jats:p>","DOI":"10.3390\/biom16071011","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T14:14:25Z","timestamp":1783692865000},"page":"1011","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Cyclodextrin-Based Delivery Systems in Cosmeceuticals: Current Advances and Future Perspectives"],"prefix":"10.3390","volume":"16","author":[{"given":"Catarina","family":"Amaro","sequence":"first","affiliation":[{"name":"Faculty of Pharmacy, University of Lisbon, 1649-003 Lisbon, Portugal"},{"name":"Research Institute for Medicines (iMed.ULisboa), Faculty of Pharmacy, Universidade de Lisboa, 1649-003 Lisbon, Portugal"},{"name":"Students Research Group (Erasmus Student), Department of Medical Biology, Medical University of Lodz, 90-151 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4559-5015","authenticated-orcid":false,"given":"Tomasz","family":"Kowalczyk","sequence":"additional","affiliation":[{"name":"Department of Molecular Biotechnology and Genetics, Faculty of Biology and Environmental Protection, University of Lodz, 90-237 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4656-3557","authenticated-orcid":false,"given":"Laurent","family":"Picot","sequence":"additional","affiliation":[{"name":"UMR CNRS 7266 LIENSs, La Rochelle Universit\u00e9, 17042 La Rochelle, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9987-4573","authenticated-orcid":false,"given":"Anna","family":"Merecz-Sadowska","sequence":"additional","affiliation":[{"name":"Department of Economic and Medical Informatics, University of Lodz, 90-214 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1019-5406","authenticated-orcid":false,"given":"Pere","family":"Verdugo","sequence":"additional","affiliation":[{"name":"Eurecat, Technology Center of Catalonia, Chemical Technologies Unit, 43007 Tarragona, Spain"},{"name":"Department of Analytical and Organic Chemistry, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9255-4697","authenticated-orcid":false,"given":"Helena","family":"Cabral-Marques","sequence":"additional","affiliation":[{"name":"Research Institute for Medicines (iMed.ULisboa), Faculty of Pharmacy, Universidade de Lisboa, 1649-003 Lisbon, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5495-3550","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"Sitarek","sequence":"additional","affiliation":[{"name":"Department of Medical Biology, Medical University of Lodz, 90-151 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pachuau, L., Das, N., Nath, R., Sutradhar, J., and Das, M.K.
