On the Amazon platform, consumers rated the product with an average of 4.8 stars. One criticism was that there was no visible effect. However, this is an isolated case. Many customers like the fact that the product is very pleasant and absorbs quickly. In our practical test , we were able to confirm that the product is absorbed quickly and does not leave a sticky film on the skin. For an optical effect, the product must be tested over a longer period of time.

Prices of up to €24.90 for 50 ml are charged on the Internet for equivalent products. Very inexpensive products are available from just €7.65 for 50 ml. The organic hyaluronic serum from “von Kinsky” is therefore currently in the middle price segment with a price of €15.99 for 50 ml. The price ratio is very good for the quality and range of services you receive.
