Abstract
Cosmetic area has increased worldwide and will continue to expand as long as there are users. At the moment, the interest leads towards cosmetics based on natural ingredients. A common aesthetic problem for majority of the people is represented by dark circles which appear in the infraorbital region. The purpose of this work was to prepare and analyze new cosmetics based on collagen and caffeine with antimicrobial activity that can be used for the treatment of dark circles. The obtained cosmetics are stable at the natural pH of the skin, indicating that new products can be securely used. Images from the optical microscopy evaluation revealed that cosmetics have a soft and foam like appearance. All the obtained cosmetics present excellent stability at 4 and 40°C. The antimicrobial activity against Staphylococcus aureus and Escherichia coli was also performed showing that the cream with collagen hydrolysate and smallest amount of caffeine is the most efficient Some more analysis need to be performed before notification.
