Resveratrol is a natural substance that has been the target of many researchers over the\nyears since it presents a variety of potential applications in the areas of cosmetics and medicine\nas a treatment for some diseases. Due to its high antioxidant capacity but low bioavailability,\nwe evaluated the antiaging potential of resveratrol as a liotropic liquid crystal emulsion. Initially, we\nperformed in vitro assays to quantify both the organoleptic characteristics and stability of the\nemulsion. Next, an in vivo trial was performed on the faces of 30 volunteers to determine the\ncream�s cosmetic potential and to measure porphyrins, skin barrier function, skin pigmentation,\nexpression lines, and porosity. The emulsion maintained its characteristics during the in vitro assays\nand, in the in vivo trial, it had some effect only on pore size in forehead, without any significant\neffects on the other parameters. We had 6 dropouts throughout the study, then the final number\nof volunteers was 24. Most volunteers did not show any changes in skin pigmentation throughout\nthe study. Similarly, there was not any noticeable improvement on any other parameters evaluated.\nHowever, volunteers related a high level of satisfaction with the product.
