Advances in Regulatory and Technological Aspects of Cosmetics

Dear Colleagues,

In recent years, we have witnessed several changes in the regulatory framework of cosmetics. The demands around the quality, safety, and efficacy of these products have been increasing. However, there is a paradigm that is worth debating: taking into account the definition of a cosmetic product described in worldwide legislation, cosmetics only have to act at the level of the upper layers of the epidermis. However, cosmetic skin delivery has a very important impact on the action of cosmetics. Meanwhile, it also brings safety issues and the customization of national laws and regulations. Scientific and technology advances currently used by the cosmetic industry, namely nano-ingredients, nanoencapsulation techniques or even the presence of skin enhancers into formulations, can lead certain cosmetic ingredients to reach other layers of the skin, keeping them out the scope of the definition of cosmetics. Therefore, formulation development, efficacy, and safety studies as well as regulatory aspects should be updated and scienced based.

This Special Issue is of great relevance since it proposes to highlight the current problems of the regulations based on science and technology. We encourage submissions on formulation development and characterization, innovations in cosmetics ingredients, and analytical, in silico/in vitro/in vivo evaluation methods on delivery pathways available to cosmetic molecules. Papers on the laws and regulations of various countries on cosmetics are particularly welcome, as well as the prospect of novel permeation enhancement technologies.

It is our pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews are welcome.
