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.
