New Trends in Skin Care: Topical Delivery of Cosmeceutical Molecules

Dear Colleagues,

In modern cosmetology, the key requirement is the employment of pure or highly concentrated active ingredients with intrinsic features of prevention or treatment of skin disorders or aging. The success of these precious ingredients, both from botanical and manmade origin, is linked to the concept of product efficacy rather than to the marketing claims or other emotive or sensorial factors.

The use of inert substrates as vehicles for the active molecules is related to the need for ensuring their stability against thermal degradation, photodegradation, and oxidation; deep penetration; and increase in local bioavailability via modulated release through a controlled mechanism. In this respect, excipients, solubilizers, penetration enhancers, gels, creams, patches, lipids, capsules, fibers, films, or any other delivery approach represent the response of the researchers from the fields of biology, chemistry, biophysics, and medicine to the demand from society for innovative products involved in skin rejuvenation and health.

Therefore, this Special Issue of Molecules is dedicated to short communications as well as original research and review articles that cover the latest findings in skin care and treatment of dermatological diseases, with particular attention to the innovations in topical delivery technologies able to enhance the efficacy and stability of cosmeceutical molecules (i.e., cosmetic ingredients with the purpose of medical benefits).
