In cosmetic industry, there is a fierce competition, having been claimed the need for renewal. Cosmetic products include cosmeceuticals, which are those that include principles with beneficial activities related to pharmaceutical industry. Natural bioactive compounds have shown various activities related to cosmetics, including antioxidant activity and the ability to protect against solar radiation. The aim of this project has been the search of active principles to obtain new dermocosmetic products. For this purpose, we have studied, characterized and selected extracts obtained from natural sources. These products were obtained from byproducts of sweet cherry and avocado industry. The scSFE extract was chosen from 3 different cherry stem extracts obtained by 3 extraction methods: pressurized solvent extraction, supercritical fluid extraction and subcritical water extraction. Furthermore, the P85 avocado peel extract was chosen from 6 avocado seed and peel extracts dried at three different temperatures. Both extracts, scSFE and P85, have shown a high antioxidant capacity in different in vitro tests, as well as the ability to protect against ultraviolet A and B radiation in a cell model. Additionally, the scSFE extract has shown the ability to inhibit enzymes that degrade components of the extracellular matrix, which is related to an anti-aging activity. Furthermore, the P85 extract has shown a melanogenic effect in a murine melanoma cell model. This activity could be due to the main compounds of both extracts, especially polyphenols. Polyphenols are bioactive compounds produced by the secondary metabolism of plants and have been widely used in traditional medicine and pharmaceutical and cosmetic industries. These activities presented by both extracts show them as potential candidates to be used in dermo-cosmetic products, particularly focused on sun protection and anti-aging products. However, future studies are necessary to determine completely the mechanism of action for these activities.
