Caffeic acid skin absorption: Delivery of microparticles to hair follicles
Graphical abstract: Emulsions containing CA were prepared, one of which contain free CA and the other microencapsulated CA. They were applied to delimited area of skin. Subsequently the tape stripping and differential striping methods were applied.
Release and permeation profiles of spray-dried chitosan microparticles containing caffeic acid

No. of bitstreams: 0 Previous issue date: 2018-03-01 Caffeic acid (CA), a phenolic compound found in plants with antioxidant and antimicrobial activity, induces collagen production and prevents premature aging of the skin. The objective of this study was to develop two types of chitosan microparticles (MP) containing CA and to relate the morphology with the release and permeation profiles. One type of MP was prepared from a hydroalcoholic solution (MPI) and the other from an aqueous solution (MPII). Their morphology and size was evaluated by high-resolution scanning electron microscopy. The release profile of CA was evaluated using the…

Guava: phytochemical composition of a potential source of antioxidants for cosmetic and/or dermatological applications
ABSTRACT Guava (Psidium guajava L.) is a native fruit of the American tropics with commercial applications for its taste, flavor and aroma. Numerous pharmacological uses have been described for it, such as the antiseptic effect of its leaves, the use of the fresh fruit and tea from its leaves for the treatment of diarrhea, dysentery, diabetes mellitus, and others. However, considering its rich composition, the guava also is a potential source of antioxidants to be used in the development of new formulations for cosmetic and/or dermatological applications, the main focus of this research. Herein, we describe the study of the phytochemical composition and the antioxidant activity of a guava e…
