| Résumé : |
The term Photoaging describes the ageing process of our skin that is caused by ultraviolet (UV) and infrared (IR) solar radiation. UV - and IR - induced damage to our skin includes, but is not limited to, DNA alterations, an increased level of cellular oxidative stress and inflammatory reaction in our skin. All of these processes lead to premature ageing and poor biomechanical characteristics.
Our laboratory has developed the active ingredient Lingostem, which is based on a polyphenolrich lingonberry (Vaccinium vitis-idaea) cell line. The anti-oxidative capacity was 11 times higher than that of the natural berries. Lingostem counteracts the negative effects of IR and UV radiation by potentiating the antioxidant response, decreasing the inflammatory reaction and reducing MMP-1 production.
Two independent in vivo studies showed the protective and restorative capacity of Lingostem. Especially impressive were the improvement of the sub-epidermal echogenic band and a significant wrinkle reduction relative to placebo. |
