Neglected Tropical Diseases (NTD) are a group of endemic diseases that cause up to one million deaths annually. Leishmaniasis and Chagas Disease are classified as NTD whose current treatments are of limited access. There is an urgent need to develop new agents to combat or alleviate the symptoms of these pathologies. The present work highlights the activities of several natural products and their derivatives which have been tested against the causative parasites of both diseases. The activities of natural products illustrate their potential to assist in the combat against NTD. Research in this area could provide an opportunity to advance medical research and to provide treatments to low- and middle-income countries.

The improvement of stability, solubility, spreadability and skin penetration of cosmetics as well as the reduction of oxidation may be achieved by nanocarriers. In that regard, many cosmetic industries have launched nanocosmetics due to their performance improvement. Sunscreens, moisturizers and anti-aging products based on nanotechnology are available worldwide. In addition, vegetable extracts loaded into nanocarriers have also been employed as a strategy to increase their skin penetration. In this chapter, the main contributions of polymeric nanocarriers, lipid nanocarriers and vesicular nanocarriers to skin care cosmetics were approached.
