The Hyaluronic Serum is a moisturizing serum. This serum contains 2% hyaluronic acid, which, in addition to collagen and elastin, are the most important skin structure components in the fight against skin aging. Hyaluronic acid is not sufficiently produced after the age of 30, so adding it is highly recommended. No other biological substance can retain as much water as hyaluronic acid, resulting in increased smoothness, softening, wrinkle reduction and a healthy skin barrier. A skin with a healthy skin barrier feels fuller and looks younger.
