... in skin ageing. Objective: The objectives were to assess ex vivo the impact of GS on skin ageing parameters and in vivo the effect of GS on the skin physiology of mature healthy volunteers after oral intake. Methods: The impact of GS on skin ageing was assessed ex vivo via different immunohistochemical...

...P. Schroeder; C. Calles; T. Benesova; F. Macaluso; J. Krutmann Solar radiation is well known to damage human skin, for example by causing premature skin ageing (i.e. photoageing). We have recently learned that this damage does not result from ultraviolet (UV) radiation alone, but also from longer...

... to a vehicle emulsion. A total of 104 voluntary healthy female test subjects were included in the study. Moisturizing properties as well as other parameters of skin ageing, like skin surface structure and skin elasticity, were determined for treatment A (vehicle) and treatment B (with 2% Ectoin) versus...
