Abstract
Natural substances have traditionally been used in skin care for centuries. There is now an ongoing search for new natural bioactives that not only promote skin health but also protect the skin against various harmful factors, including ultraviolet radiation and free radicals. Free radicals, by disrupting defence and restoration mechanisms, significantly contribute to skin damage and accelerate ageing. Natural compounds present in plants exhibit antioxidant properties and the ability to scavenge free radicals. The increased interest in plant chemistry is linked to the growing interest in plant materials as natural antioxidants. This review focuses on aromatic and medicinal plants as a source of antioxidant substances, such as polyphenols, tocopherols, carotenoids, ascorbic acid, and macromolecules (including polysaccharides and peptides) as well as components of essential oils, and their role in skin health and the ageing process.
Highlights
The world of plants is one of the main sources for materials used in the food, pharmaceutical and cosmetics industries
In addition to the aromatic effects of plants, emphasis is placed on their antioxidant properties and ability to modulate certain types of skin damage resulting from harmful environmental factors, including ultraviolet radiation (UVR) and free radicals [4]
Those derived from plants play an important role in preventing and repairing skin damage caused by free radicals
Summary
The world of plants is one of the main sources for materials used in the food, pharmaceutical and cosmetics industries. In addition to the aromatic effects of plants, emphasis is placed on their antioxidant properties and ability to modulate certain types of skin damage resulting from harmful environmental factors, including ultraviolet radiation (UVR) and free radicals [4]. Free-radical reactions take place in most cells of the human body. They mediate important cellular processes such as growth, proliferation, differentiation, and apoptosis [6,13]. The aim of the present review is to describe the role of free radicals and OxS in the physiology and ageing of the skin, and to discuss the role of selected bioactive compounds of plant origin in skin health and the ageing process
