Sinerga’s Dolcevia® (INCI: Stevioside) is a natural pure glycoside extracted from the dry leaves of the well-known Stevia rebaudianaplant.
The ingredient minimises smooth muscle contractions, acting like a natural skin de-stressing agent that reduces the muscles’ involuntary microtensions and restores skin wellness.
Stevioside’s relaxing activity has been associated to different targets on smooth muscles. In order to better validate the spasmolytic activity and the potential skin care applications as a ‘de-stressing’ agent, Sinerga conducted tests to determine its efficacy as a potential skin ‘de-stresser’ for various anti-ageing formulations.
In this article are shown the methods and results of clinical tests demonstrating the effect of Dolcevia on overall facial appearance including wrinkles. After only 7 days of treatment, PRIMOS results show a decrease of wrinkle depth (17%), wrinkle height (14%) and average roughness (14%).
