Another 2% vitamin Cg (ascorbyl glucoside) could be obtained for the formula to promote long-term and active the Ebenmaeigkeitsbild and the radiance of the skin.
To further reduce the appearance of wrinkles, the formula of the new Powerful Strength Line Reducing Concentrate was also based on hyaluronic acid.

The new, adapted formula is rounded off by even longer shelf life and correspondingly greater efficiency and gives the skin a warming effect for true wellbeing moments when applied. The new formulation also impresses with a fresh citrus aroma.
