Free radicals are unstable molecules that form in the body and on the skin as a result of natural metabolic processes, as well as external factors such as UV radiation, pollution, cigarette smoke and stress. Because of their reactivity, free radicals can damage cellular structures and disrupt the skin’s natural protective barrier. They also affect the hair. By triggering oxidative stress in the follicles, they can weaken the hair roots, while on the surface of the hair shaft they damage proteins and lipids, leading to dryness, brittleness and loss of shine.
In cosmetics, free radicals are associated with oxidative stress, which can cause wrinkles, fine lines, uneven skin tone and hair damage. Products rich in antioxidants, such as vitamin C, vitamin E, hyaluronic acid and plant extracts, help neutralise free radicals, reduce their harmful effects and protect the skin and hair.
Regular use of such products supports skin and follicle renewal, helping maintain smooth, radiant and resilient skin, as well as shiny, strong and healthy hair.
