Dear Colleagues,

The oceans and seas are a great place to find natural active and functional materials for personal care products. The marine environment has been demonstrated to be a rich source of structurally-diverse, biologically-active compounds with excellent and unique cosmetic potentials. This is due, in part, to the differences in the physicochemical nature of sea environments, where conditions of high pressures, low temperatures, lack of light, and high ionic concentrations may lead to the biosynthesis of highly-functionalized and unusual molecules in marine organisms.

Despite the multitude of cosmetic products based on traditional marine sources, only a tiny proportion of their full potential has been exploited. We are familiar with using marine materials: Marine organisms produce unique compounds that have been used both to confer physicochemical functional properties, such as texture, emulsifying properties or color, bioactive properties, including remineralizing, emollient, hydrating, antioxidant, and sunscreening among others.

We use everything from seawater to a huge range of extracts made from seaweed, microalgae, plankton, coral and many other marine organisms, but the most exciting new materials remains largely unexplored.

Moreover, there is a great potential in the marine bioprocess industry to convert and utilize most of marine resources and marine food by-products to valuable cosmeceutical ingredients.

Researchers are invited to provide recent and innovative research and results, encompassing various aspects of marine compounds and extracts, potentially useful in the cosmetic world.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Marine Drugs is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
