The skin aging process is influenced by many factors which can be intrinsic, such as sex, genetics and age, or external, such as exposure to sunlight, stress and lifestyle.<\/p>\n

However, although less known, the main cause of this natural process is the uncontrolled increase in reactive oxygen species (ROS), i.e. a type of free radical containing oxygen that is normally generated during cellular respiration. In aging, this oxidative stress is associated with both an increase in ROS production and a decrease in our body’s defense mechanisms [1]. The latter makes use of enzyme action produced by our own body and natural antioxidants, introduced through our diet (for example vitamin E) or applied locally through cosmetic products.<\/p>\n

To effectively counteract the formation of new ROS and slow down skin aging, a continuous supply of antioxidant molecules is necessary, which by nature have a fairly short life cycle.<\/p>\n

How to protect your skin from oxidative stress<\/h2>\n

Skin aging is also accompanied by a decrease in activity of the skin’s secretory glands, the sebaceous glands, with a consequent reduction in the surface lipid membrane and skin hydration [2]. Furthermore, renewal of the outer layer of skin is increasingly slower: usually the skin then becomes dry, rough, more sensitive and susceptible to inflammatory phenomena [3].<\/p>\n

Hence the importance of using cosmetics specially formulated to protect the skin from external pro-oxidative agents and keep it properly hydrated, especially in the areas most exposed to external agents, i.e. hands and face. Numerous experimental tests highlight how antioxidant compounds such as polyphenols<\/strong>, ascorbic acid<\/strong> (vitamin C), tocopherols<\/strong> (vitamin E) and other natural substances reduce oxidative stress<\/strong> and slow down the skin aging process [4]. Polyphenols are among the most studied and we have begun to decipher the molecular mechanisms through which they exert their anti-aging function on dermal cells [5]. Obviously their presence within a cosmetic formulation is not sufficient in itself. The concentrations must be adequate and calibrated to inhibit the pro-oxidative activity of reactive oxygen species and other free radicals.<\/p>\n

Dionisia line: proven antioxidant efficacy<\/h2>\n

In the laboratories of the Istituto Italiano di Tecnologia<\/a><\/strong> we experimentally verified the protective and antioxidant effect offered by the extracts of Monterosso al Mare grapes, which proved to be much richer in polyphenols than others similar in nature.<\/p>\n

From the result of this research our first anti-aging line Dionisia was born.<\/p>\n

In the cosmetic products of the Dionisia Line we have included a quantity of extract equal to or greater than that tested in vitro<\/em> on cells and included other precious antioxidant compounds to promote a synergistic and more effective function.<\/p>\n

Below we will see which ones.<\/p>\n
