Quite frankly, this is one of the best anti-aging serums we've tested. It's no wonder this German brand is featured in 5 Star spas around the world. Our test subject for this product was a 70 year old woman with deep wrinkles and age spots. The results after our 30 day review were amazing. Her skin was brighter, firmer, and super smooth--it looked like she had work done (in a good way!). While we could go on and on about the ingredients in this serum (like their "Living Beauty Complex" made with rose gold, vitamin C, and spirulina), the truth is that the whole formula is simply perfection.
