GIACOMONI, PhD 2019–2021 Journal of Cosmetic Science Editor-in-Chief Dear Readers, As a goodbye to all of you after three years as Editor-in-Chief of the Journal of Cosmetic Science, I would like to share some information and some feelings about the JOCS. Credit must be given to Mike Fevola who, six years ago, started a new strategy to boost the impact factor. I have tried to implement that strategy. The JOCS is particularly attentive to manuscripts related to the physical chemistry of formulations and the results of clinical testing. Manuscripts describing animal testing results are considered beyond the scope of the Journal, as are manuscripts drawing conclusions about possible clinical effects from experiments performed with cultured cells. We have received many manuscripts related to consumer behavior, marketing, religious guidelines about cosmetics, and the like: these topics have been considered to be beyond the scope of the Journal. On the other hand, manuscripts describing results of clinical experiments performed with ingredients whose efficacy was suggested by experiments with cultured cells are welcome, as are in vitro experiments performed to understand the action mechanisms of ingredients with proven clinical efficacy. The impact factor is increasing: 0.269 in 2015, 0.222 in 2016, 0.436 in 2017, 0.318 in 2018, 0.530 in 2019, and 0.948 in 2020. We will have to wait until next year to see whether this trend continues. The new Editor-in-Chief, Trefor Evans, is a brilliant scientist and a rigorous reviewer. I am confident he will serve the JOCS to the best of his ability. Last but not least, we were lucky to have a panel of dedicated, expert reviewers who provided constructive comments to improve manuscripts, which made the authors quite happy. I wish you all a successful new year! J. Cosmet. Sci., 73, 1 (January/February 2022)

2 Letter from Incoming Editor-in-Chief TREFOR EVANS, PhD 2022–2024 Journal of Cosmetic Science Editor-in-Chief In 1665, The Philosophical Transactions of the Royal Society became the first scientific journal—being a monthly publication of the Royal Society’s meetings—where such legendary scientific names as Robert Boyle and Robert Hooke met under a common mission to “acquire knowledge through experimental investigation.” It is a pleasant thought to consider that our own society and journal are part of the resulting lineage. In the scientific community, the reputation of the journal and the society often go hand in hand. The reputation of a journal is largely judged by what is termed an “impact factor.” As incoming Editor-in-Chief, my goal is to carry on the work of my predecessors by trying to grow this metric. Still, achieving this target requires the help of all our members and readers. At the simplest level, the impact factor reflects the interest level of a journal’s published material and is largely quantified by the frequency such articles are cited by others. In principle, achieving the goal involves attracting and publishing papers that are of paramount interest to other researchers in the field. Conversely, those of minor interest provide a diluting effect. Accordingly, this criterion is an overriding consideration when assessing the suitability of submissions. We, therefore, respectfully ask all members and all readers to consider submitting your own novel scientific research to the Journal of Cosmetic Science for consideration to publish. Currently, our society consists of approximately 5,400 members, yet a highly disproportionate number of submissions come from outside our ranks. We are happy to consider all submissions and relish the international reach of our journal but, at the same time, we would like to attract more domestic interest. All submissions will be evaluated by reviewers who are active researchers in that specific scientific area. Additional acceptance gauges include: (1) Is the content relevant to a cosmetic scientist? (2) Does the manuscript describe an original body of work previously unreported in open literature? (3) Are the results reported in such a way that an expert in the field could repeat the work? Please use the following link to submit an abstract - https://jcs.scholasticahq.com/for-authors In advance, I would like to thank our expanding list of highly experienced Assistant Editors and technical reviewers whose efforts will make this goal a realization. I look forward to my next three years as Editor-in-Chief of the Journal of Cosmetic Science and hope we can further advance our impact factor, electronic presence, and the turnaround time for peer review.
